REBA+: Robots Exploring Tools

In the project REBA+, funded within DFG priority program "Autonomous Learning", we develop, implement and evaluate rich extensions of a robot's body schema, along with learning algorithms that use these representations as strong priors in order to enable rapid and autonomous usage of tools and a flexible coping with novel mechanical linkages between the body, the grasped tool and target objects.

TACT-HAND: Improving control of prosthetic hands using tactile sensors and machine learning

Computer aided rendering of tactile sensor units fitting onto the I-limb Ultra prosthetic hand Despite decades of research, intuitive and robust control of multi-joint prosthetic hands is still an unsolved problem, largely due to missing sensorization of the hand and a poor human-machine interface, that only barely can recognize the intent of the patient. In this project we will employ and evaluate a new generation of tactile sensors coupled with modern machine learning approaches to overcome both problems.

WearHap: Wearable haptics for Humans and Robots

Tactile sensitive datagloveWithin the EU-Project WearHap, we develop different wearable devices, most notably a tactile-sensing glove, based on our elastic, fabric-based tactile-sensor-technology. The Tactile Glove provides normal force/pressure measurement in approx 60 taxels spread across the whole palmar side of the hand and allows to record human interaction forces while grasping or manipulating objects.

Tactile Sensing

Providing the sense of touch to robots is one of the most important challenges to advance towards more complex manipulation capabilities in robotics. We are developing tactile sensors for use in robot hands, sensorized objects, and human data gloves. Futhermore we are developing Tactile Servoing methods exploiting tactile sensors directly for robot control. read more »

What does a hand-over tell? - Comparative analysis of kinematic data

Which relations exist between properties of animals or people and their kinematic patterns? For example, can we tell, who performed a hand-over of which kind of object under which conditions just by looking at the sequence of joint angles? We try to find answers to these questions by employing a 3D motion tracking system.

Online 3D Scene Segmentation

A major pre-requisite for many robotics tasks is to identify and localize objects within scenes. Our model-free approaches to scene segmentation employs RGBD cameras to segmented highly cluttered scenes in real-time (30 Hz). To this end, we first identify smooth object surfaces and subsequently combine them to form object hypotheses employing basic heuristics such has convexity, shape alignment and color similarity.
