In this thesis, a neural network model is trained to learn the state transition function of a hydraulic excavator arm or a crane using data driven approach. The excavator arm or crane exhibits highly non linear behaviour due to hydraulic coupling between its actuators, non linearities in valves, par…

Final presentation: Imaging sonar is commonly used in underwater detection tasks, as it can provide acoustic imaging of underwater environments in low or zero visibility conditions where optical sensors fail. The forward-looking sonar (FLS) is commonly used for monitoring tasks due to its capabilit…

Evaluation of metrics for human-like grips

von: Florian Seidler  (Universität Bremen)
For each grasp, there are a large number of possible contact points with different properties. The quality of grasps can be determined using metrics. Metrics are tools that can be used to measure a specific characteristic of a process.  To mimic human grasping, these metrics could be used. Howe…

Ambient Air Pollution Prediction

von: Hannes Gelbhardt  (Universität Bremen)
Ambient air pollution is well known to affect humans and the environment severely. Some primary sources of air pollution are industrial processes, motorized traffic, wildfires, and volcanic activities. Estimating future air pollution concentrations can lower the effects on humans and the environment…

Air-bearing-based platforms are used to simulate microgravity on Earth. Therefore, these platforms can be used to test for example Active Space Debris Removal (ASDR) maneuvers. European Space Agency’s Orbital Robotics and GNC Lab (ORGL) features a 5m × 9m flat floor. A 220 kg heavy air-bearing platf…

Mechatronic Design and Control of an Underactuated Three-link Brachiation Robot

von: Shourie Grama Srinivas  (École Centrale de Nantes, Nantes, France)
Brachiation is a type of locomotion achieved by swinging from place to place, employed by Monkeys (mostly Gibbons). During brachiation, if the Gibbon encounters a distant branch such that it is expected to have a dynamic free flight phase in its motion, this rapid motion mode is called 'Fast Brachia…

Multi-agent deep reinforcement learning (MADRL) is a powerful approach that enables agents to coordinate and collaborate to solve complex collaborative tasks. Applications of MADRL range from robotics to traffic control and resource allocation. However, the learning process can be slow, especially w…

Robot state estimation using Synthetic RGB images

von: Vasantakumaar, Naren  (Universität Bremen)
The aim of this thesis is to use a camera as a cost-effective alternative to the expensive retrofitting of sensors for state estimation of the manipulator. Determining the state of robot joints from images has always been a challenge in the field of computer vision and robotics. Thus, determining th…

Zwischenbericht
Long-term autonomous robotic missions, especially in isolated environments, have to cope with various challenges, e.g., limited possibilities for maintenance or recovery in case of failure. Better adaptation of the robot to its environment is therefore the first step towards a more robust behavioura…
