Collision avoidance for safe human-robot-coexistence

Research

Recently, the need for a robot that collaborates with humans has increased not only in the industrial settings but also in home use. It is certain that the opportunities that robots associates with humans increase from now on, and human safty becomes a big problem.
In our research, we propose a collision avoidance system in which high-speed camera heads are placed on a robot manipulator. The manipulator can avoid the fast moving obstacle. The arm link is controlled so that the obstacle describes a spiral on the image plane, and the trajectory of the end effector describes a spiral.
