Hand-made robot prototype

We present a robot interaction system by introducing Labanotation into the working process. In real world scenario, there are several ways of programming a robot. But due to the kinematic and dynamic difference between human and robots, or even different robots themselves, simple mimicking method to repeat exactly the same joint angles will not work. So we bring Labanotation, a notation being used to record dance, as an intermediate symbolic representation for imitation of human’s upper body motion. In our system, a person performs series of actions in front of a Kinect first. Human skeleton information is captured and processed into so-called “energy function”. Peaks in the energy function are detected and treated as time point of key poses. A sequence of Labanotation is generated from the skeleton information (a.k.a. key pose) of the corresponding time points. After that, the Labanotation is sent to different robots. Robots receive the message then interpret Labanotation according to its’ own kinematics structure to mimic human action.

Procedures for using Labanotation as intermediate language of robot control.

For tasks that do not request precise manipulation, the biggest benefits of doing this is time-saving for motion editing to different robots. Engineers only need to program the robot once to set up rules of mapping Labanotation symbols. Then robots are able to interpret any Labanotation sequences.
