ABSTRACT
In this paper, problems in instructing an industrial robot by means of a control panel are investigated. In order for the robot to learn as much and as fast as possible from demonstration, the demonstration by the teacher needs to be as precise as possible. Usability studies constitute a useful methodology to investigate in which situations users provide the robot with exact trajectories and, if not, why they face difficulties. Results show that movements involving only the lowest joint of the robot arm are straight-forward and very exact. In contrast, fine movements that involve joints of the upper arm cause considerable problems. The analysis shows that users have to employ separate actions instead of focusing on the target and therefore need to consciously plan the action since they cannot match the robot's movements with those of their own embodiment.

Learning from Demonstration for Autonomous Navigation in Complex Unstructured Terrain
Rough terrain autonomous navigation continues to pose a challenge to the robotics community. Robust navigation by a mobile robot depends not only on the individual performance of perception and planning systems, but on how well these systems are ...
Human-like coordination motion learning for a redundant dual-arm robot
Highlights- A human-like coordination motion learning method is developed for making robotic dual-arm manipulations more smooth and natural.
AbstractThe motion of a redundant dual-arm robot is subject to dual-arm coordination constraints when performing a coordination task. However, these constraints are usually fixed. To improve the ability of dual arm robots to interact ...
