Vision-Based Teleoperation of the Compliant RBO Hand 3 [1]
Humans are experts in operating anthropomorphic hands based on
their intuition. However, transfer of intuitive manipulation
strategies requires tools that can capture relevant aspects that
govern human behaviors.
More specifically, we want to transfer robust human in-hand
manipulation strategies to the anthropomorphic RBO Hand 3. At the
moment, this hand’s actuators are operated using a mixing board: a
tedious and unintuitive process. In this work, we design a general
vision-based teleoperation system that lets users operate the robot
hand by mirroring intuitively produced movements from their own hand.

Compensating the Pneumatic Actuation Noise by Using Strain and
Acoustic Signals [3]
To estimate the robot state and
environment, we can use different sensors. For example, we can measure
the sound inside of soft pneumatic actuators and use small changes in
the sound signal to sense a wide range of actuator properties (Active
Acoustic Sensor). Alternatively, strain sensors attached to the robot
finger measure the deformation of the soft hull (Strain Sensor).
While each sensor has shown promising results in different tasks, some
disturbances lead to data corruption or loss. To achieve a robust
sensor prediction, we combine multiple sensors. Additionally, this
fusion might also give us more information about the pneumatic
actuator state and environmental interaction and may thereby lead to a
more precise contact location detection.

Studying Abductive Reasoning by Playing Mastermind [5]
Mastermind is a simple, but very clever code-breaking board game
from the 70s. It is a perfect example of abductive reasoning, also
called inference to the best explanation. Abduction is a method of
(scientific) reasoning in which one chooses the hypothesis that best
explains the available evidence. Abduction is the third type of logic
inference, in addition to deductive and inductive reasoning. For
example, medical doctors perform abduction when diagnosing a disease
(hypothesis) given the observable symptoms (evidence). Abductive
reasoning can produce false hypotheses, for example, because there
might be several diseases producing similar symptoms. Doctors then go
through progressively complex tests, successively decreasing the set
of possible diseases matching the evidence – in principle very
similar to playing Mastermind.
