  • Active Viewpoint Selection for Mobile Robot Perception | Current Topics

    A robot driving around a room often observes an object from an awkward position, where it may be partly hidden behind furniture, too distant, or lit from behind. A conventional vision pipeline runs an object detector on whatever image is available and accepts the result even when confidence is low. A robot on wheels, unlike a fixed camera, has a further option open to it: moving to a different position and observing again. Choosing where to look next, rather than only interpreting what is already in view, is known as active perception.

  • Mixed Reality Interaction Layer for UAV Swarm Control and Monitoring | Current Topics

    Swarms of unmanned aerial vehicles (UAVs) are used in search and rescue, infrastructure inspection, and environmental monitoring. An operator supervising such a swarm has to follow many vehicles at once, understand where they are relative to one another, and issue commands to groups rather than to single drones. Ground control stations present this three-dimensional situation on flat screens, which leaves the operator to reconstruct the spatial picture mentally. A Mixed Reality (MR) headset can instead place drone positions, planned trajectories, and status information in the space where the drones actually fly.

Aerial Robot Swarms

  • Localization Quality-Aware Trajectory Planning for Aerial Robot Swarms | Current Topics

    This project uses small quadcopter drones, open-source research platforms known as Crazyflies, which are light enough to fly safely inside an ordinary room. Since GPS is unavailable indoors, position has to be established by other means, and these drones rely on a room-tracking system called Bitcraze Lighthouse. Small base stations mounted around the flight area, originally developed for virtual-reality headsets, sweep invisible infrared light across the space, while a receiver board on each drone detects these sweeps and computes its own position onboard many times per second. With four base stations placed around the room, the same calibrated setup can track a single drone or a small group.

However, our standard processes for managing software—like Git feature branches and pull requests—were created over two decades ago when writing code by hand was a slow process. Because code generation is now nearly instant, the main bottleneck in software engineering has shifted from writing code to reviewing, testing, and integrating it.

AI Safety

  • Guardrails for Foundational Model Enabled Robots | Current Topics

    Foundation models let a robots accept missions in natural language, but they also let a wrong or malicious instruction reach the propellers. PEACE [1] is a planner–executor agent for robots in which a large language model emits a complete, typed mission plan in a single call, and an independent safety service validates every motion command before actuation. That service currently enforces two geometric constraints: an altitude band and a horizontal geofence. It cannot express, let alone enforce, the rules that matter in the real world: keep distance from people, do not hover in front of windows, maintain a minimum altitude over roads, respect regulatory limits. This project replaces the geometric check with a two-tier guardrail: a plan-level check that grounds natural-language safety rules into formal specifications and verifies the whole mission plan before dispatch, and an execution-level check that grounds the same rules into spatial keep-out sets around detected objects.

  • Red-Teaming Foundational Model Enabled Robots | Current Topics

    Large language models (LLMs) are increasingly used as high-level planners for robots: a natural-language mission is turned into a sequence of actions that a classical controller executes. Recent work has shown that such LLM-controlled robots can be jailbroken into performing physically harmful actions, often with 100% attack success, on commercial platforms [1]. Proposed defenses either wrap the planner in a guardrail [2] or restrict what the planner may emit. Planner–executor agents such as PEACE [3] take the second route: the LLM produces a single, fully typed plan over a fixed tool schema instead of free-form code or a step-by-step reasoning loop. Whether this architectural choice actually reduces the attack surface has never been measured. This project builds a reusable red-teaming harness for LLM-enabled robot planners in simulation and uses it to compare architectures under a common set of attacks.

Navigation policies for such robots are increasingly learned through reinforcement learning or imitation. When a learned policy meets a situation outside its training data, it still produces an action, and nothing in that action tells the robot or its operator that the policy may be wrong.

  • Extending the X-TPL Dataset with additional Hybrid Android App Frameworks and Native Android Apps | Current Topics

    The idea of this project is to extend an exsting dataset for Android apps and their third-party libraries. Our current research relies on a foundational dataset of Android hybrid applications to analyze Third-Party Library (TPL) usage and associated security risks. The dataset contains currently Flutter, .NET MAUI, React Native, and Apache Cordova apps and we want to extend this with additional frameworks, such as Ionic or Unity. While we already maintain an automated data acquisition pipeline, this seminar project focuses on extending its capabilities to systematically crawl, download, and build applications built with additional modern hybrid frameworks (such as Ionic, Unity, etc.) from public repositories (e.g., GitHub, Gitlab, etc.). Crucially, this project will also expand the pipeline and dataset to include purely native Android applications. This native inclusion will serve as a vital control group, enabling comparative benchmarks that highlight architectural, performance, and security differences between native and cross-platform paradigms.

  • Third-Party Library Detection for Hybrid Android Apps | Current Topics

    Modern Android applications are increasingly built using hybrid frameworks such as React Native, Flutter, and Cordova, allowing developers to deploy apps across multiple platforms with a single codebase. Like native apps, hybrid applications heavily rely on Third-Party Libraries (TPLs) to accelerate development and integrate functionalities like analytics, advertising, and UI components. However, TPLs can introduce severe security vulnerabilities and privacy risks. While numerous techniques exist to detect TPLs in native Android applications (analyzing Dalvik bytecode), identifying TPLs in hybrid apps remains a significant challenge. This project aims to bridge this gap by investigating the structure of hybrid apps and developing a novel approach to accurately detect embedded TPLs within their non-native components (e.g., JavaScript bundles, Dart binaries).

Anomaly Detection

  • Unsupervised Anomaly Detection for Merge Conflict Resolution | Current Topics

    This topic investigates unsupervised anomaly detection for merge conflict resolution in software engineering. Existing approaches generally formulate conflict resolution as supervised classification over predefined resolution labels. However, even a large labeled dataset may contain rare, unusual, or incorrectly reconstructed cases, and the labels may not adequately represent the full diversity of merge behavior. This project will develop methods to identify anomalous merge conflicts using the available conflict representations while initially ignoring the nine resolution labels. The objective is to determine whether anomaly scores can identify unusual conflict structures, rare resolution patterns, or cases that are difficult for conventional classifiers.

  • Vision-Guided Motion Planning and Control for Robotic Manipulators | Current Topics

    Low-cost robotic arms are usually driven by scripts that command each joint directly, which is adequate for a demonstration but rarely transfers to the next project and offers no protection against the arm moving through an obstacle or into itself. Robotics addresses this with two standard pieces of software: the first gives programs a common way to communicate with real or simulated motors and is called ROS 2 Control, while the second computes the joint angles needed to reach a position, checks the path for collisions, and plans a safe movement, and is called MoveIt 2. Taken together, they turn a one-off script into a reusable arm setup that transfers between simulation and hardware.

LLM-Enabled Robots

  • Guardrails for Foundational Model Enabled Robots | Current Topics

    Foundation models let a robots accept missions in natural language, but they also let a wrong or malicious instruction reach the propellers. PEACE [1] is a planner–executor agent for robots in which a large language model emits a complete, typed mission plan in a single call, and an independent safety service validates every motion command before actuation. That service currently enforces two geometric constraints: an altitude band and a horizontal geofence. It cannot express, let alone enforce, the rules that matter in the real world: keep distance from people, do not hover in front of windows, maintain a minimum altitude over roads, respect regulatory limits. This project replaces the geometric check with a two-tier guardrail: a plan-level check that grounds natural-language safety rules into formal specifications and verifies the whole mission plan before dispatch, and an execution-level check that grounds the same rules into spatial keep-out sets around detected objects.

  • Red-Teaming Foundational Model Enabled Robots | Current Topics

    Large language models (LLMs) are increasingly used as high-level planners for robots: a natural-language mission is turned into a sequence of actions that a classical controller executes. Recent work has shown that such LLM-controlled robots can be jailbroken into performing physically harmful actions, often with 100% attack success, on commercial platforms [1]. Proposed defenses either wrap the planner in a guardrail [2] or restrict what the planner may emit. Planner–executor agents such as PEACE [3] take the second route: the LLM produces a single, fully typed plan over a fixed tool schema instead of free-form code or a step-by-step reasoning loop. Whether this architectural choice actually reduces the attack surface has never been measured. This project builds a reusable red-teaming harness for LLM-enabled robot planners in simulation and uses it to compare architectures under a common set of attacks.

Localization Quality

  • Localization Quality-Aware Trajectory Planning for Aerial Robot Swarms | Current Topics

    This project uses small quadcopter drones, open-source research platforms known as Crazyflies, which are light enough to fly safely inside an ordinary room. Since GPS is unavailable indoors, position has to be established by other means, and these drones rely on a room-tracking system called Bitcraze Lighthouse. Small base stations mounted around the flight area, originally developed for virtual-reality headsets, sweep invisible infrared light across the space, while a receiver board on each drone detects these sweeps and computes its own position onboard many times per second. With four base stations placed around the room, the same calibrated setup can track a single drone or a small group.

Merge Conflict Resolution

  • Unsupervised Anomaly Detection for Merge Conflict Resolution | Current Topics

    This topic investigates unsupervised anomaly detection for merge conflict resolution in software engineering. Existing approaches generally formulate conflict resolution as supervised classification over predefined resolution labels. However, even a large labeled dataset may contain rare, unusual, or incorrectly reconstructed cases, and the labels may not adequately represent the full diversity of merge behavior. This project will develop methods to identify anomalous merge conflicts using the available conflict representations while initially ignoring the nine resolution labels. The objective is to determine whether anomaly scores can identify unusual conflict structures, rare resolution patterns, or cases that are difficult for conventional classifiers.

  • Validating the Correctness of Merge-Conflict Resolution Labels | Current Topics

    This topic investigates the quality and correctness of nine automatically assigned labels for merge-conflict resolutions. The labels were reconstructed by replaying historical Git merges and mapping the tentative conflict representation to the final developer-committed file. Such mappings are reproducible and scalable, but they can be affected by formatting changes, reordered code, structural edits, ambiguous correspondence between conflict chunks, and compound resolutions. The project will develop methods to detect potentially incorrect, ambiguous, or unstable labels and will validate a sample of these cases through systematic inspection. The work combines supervised, unsupervised, and weakly supervised methods for label-quality assessment.

  • Mixed Reality Interaction Layer for UAV Swarm Control and Monitoring | Current Topics

    Swarms of unmanned aerial vehicles (UAVs) are used in search and rescue, infrastructure inspection, and environmental monitoring. An operator supervising such a swarm has to follow many vehicles at once, understand where they are relative to one another, and issue commands to groups rather than to single drones. Ground control stations present this three-dimensional situation on flat screens, which leaves the operator to reconstruct the spatial picture mentally. A Mixed Reality (MR) headset can instead place drone positions, planned trajectories, and status information in the space where the drones actually fly.

    Low-cost robotic arms are usually driven by scripts that command each joint directly, which is adequate for a demonstration but rarely transfers to the next project and offers no protection against the arm moving through an obstacle or into itself. Robotics addresses this with two standard pieces of software: the first gives programs a common way to communicate with real or simulated motors and is called ROS 2 Control, while the second computes the joint angles needed to reach a position, checks the path for collisions, and plans a safe movement, and is called MoveIt 2. Taken together, they turn a one-off script into a reusable arm setup that transfers between simulation and hardware.

Native Applications

  • Extending the X-TPL Dataset with additional Hybrid Android App Frameworks and Native Android Apps | Current Topics

    The idea of this project is to extend an exsting dataset for Android apps and their third-party libraries. Our current research relies on a foundational dataset of Android hybrid applications to analyze Third-Party Library (TPL) usage and associated security risks. The dataset contains currently Flutter, .NET MAUI, React Native, and Apache Cordova apps and we want to extend this with additional frameworks, such as Ionic or Unity. While we already maintain an automated data acquisition pipeline, this seminar project focuses on extending its capabilities to systematically crawl, download, and build applications built with additional modern hybrid frameworks (such as Ionic, Unity, etc.) from public repositories (e.g., GitHub, Gitlab, etc.). Crucially, this project will also expand the pipeline and dataset to include purely native Android applications. This native inclusion will serve as a vital control group, enabling comparative benchmarks that highlight architectural, performance, and security differences between native and cross-platform paradigms.

A robot on wheels, unlike a fixed camera, has a further option open to it: moving to a different position and observing again. Choosing where to look next, rather than only interpreting what is already in view, is known as active perception.

    This project uses small quadcopter drones, open-source research platforms known as Crazyflies, which are light enough to fly safely inside an ordinary room. Since GPS is unavailable indoors, position has to be established by other means, and these drones rely on a room-tracking system called Bitcraze Lighthouse. Small base stations mounted around the flight area, originally developed for virtual-reality headsets, sweep invisible infrared light across the space, while a receiver board on each drone detects these sweeps and computes its own position onboard many times per second. With four base stations placed around the room, the same calibrated setup can track a single drone or a small group.

  • Active Viewpoint Selection for Mobile Robot Perception | Current Topics

    A robot driving around a room often observes an object from an awkward position, where it may be partly hidden behind furniture, too distant, or lit from behind. A conventional vision pipeline runs an object detector on whatever image is available and accepts the result even when confidence is low. A robot on wheels, unlike a fixed camera, has a further option open to it: moving to a different position and observing again. Choosing where to look next, rather than only interpreting what is already in view, is known as active perception.

  • Comparative Evaluation of Vision-Based SLAM for Mobile Robots | Current Topics

    A robot moving through an unfamiliar building must build a picture of its surroundings and work out where it sits within them at the same time. Solving both problems together from camera images is known as SLAM, short for simultaneous localization and mapping. The cameras used here record a normal colour image together with the distance to everything in view; such devices are called depth cameras, or RGB-D cameras, and they suit indoor robots because they provide both appearance and scale without the cost of a laser scanner. Many open-source SLAM systems exist, and they differ considerably in how they store the map, how they recognize a place already visited, how much computing power they require, and how well they cope with dim light or rapid motion.

  • Epistemic Uncertainty as an Early Warning of Unsafe Robot Navigation Around People | Current Topics

    Indoor service robots carry medication, lab samples, and supplies through hospital corridors and move goods through warehouse aisles. They share this space with people who are not trained operators and who are often not paying attention to the robot. Navigation policies for such robots are increasingly learned through reinforcement learning or imitation. When a learned policy meets a situation outside its training data, it still produces an action, and nothing in that action tells the robot or its operator that the policy may be wrong.

UAV Swarms

  • Mixed Reality Interaction Layer for UAV Swarm Control and Monitoring | Current Topics

    Swarms of unmanned aerial vehicles (UAVs) are used in search and rescue, infrastructure inspection, and environmental monitoring. An operator supervising such a swarm has to follow many vehicles at once, understand where they are relative to one another, and issue commands to groups rather than to single drones. Ground control stations present this three-dimensional situation on flat screens, which leaves the operator to reconstruct the spatial picture mentally. A Mixed Reality (MR) headset can instead place drone positions, planned trajectories, and status information in the space where the drones actually fly.

Unsupervised Learning

  • Unsupervised Anomaly Detection for Merge Conflict Resolution | Current Topics

    This topic investigates unsupervised anomaly detection for merge conflict resolution in software engineering. Existing approaches generally formulate conflict resolution as supervised classification over predefined resolution labels. However, even a large labeled dataset may contain rare, unusual, or incorrectly reconstructed cases, and the labels may not adequately represent the full diversity of merge behavior. This project will develop methods to identify anomalous merge conflicts using the available conflict representations while initially ignoring the nine resolution labels. The objective is to determine whether anomaly scores can identify unusual conflict structures, rare resolution patterns, or cases that are difficult for conventional classifiers.

  • Validating the Correctness of Merge-Conflict Resolution Labels | Current Topics

    This topic investigates the quality and correctness of nine automatically assigned labels for merge-conflict resolutions. The labels were reconstructed by replaying historical Git merges and mapping the tentative conflict representation to the final developer-committed file. Such mappings are reproducible and scalable, but they can be affected by formatting changes, reordered code, structural edits, ambiguous correspondence between conflict chunks, and compound resolutions. The project will develop methods to detect potentially incorrect, ambiguous, or unstable labels and will validate a sample of these cases through systematic inspection. The work combines supervised, unsupervised, and weakly supervised methods for label-quality assessment.

  • Extending the X-TPL Dataset with additional Hybrid Android App Frameworks and Native Android Apps | Current Topics

    The idea of this project is to extend an exsting dataset for Android apps and their third-party libraries. Our current research relies on a foundational dataset of Android hybrid applications to analyze Third-Party Library (TPL) usage and associated security risks. The dataset contains currently Flutter, .NET MAUI, React Native, and Apache Cordova apps and we want to extend this with additional frameworks, such as Ionic or Unity. While we already maintain an automated data acquisition pipeline, this seminar project focuses on extending its capabilities to systematically crawl, download, and build applications built with additional modern hybrid frameworks (such as Ionic, Unity, etc.) from public repositories (e.g., GitHub, Gitlab, etc.). Crucially, this project will also expand the pipeline and dataset to include purely native Android applications. This native inclusion will serve as a vital control group, enabling comparative benchmarks that highlight architectural, performance, and security differences between native and cross-platform paradigms.
