Mechanical model of competition and cooperation?
We investigate what kind of dynamics will occur when autonomous agents are mechanically connected with each other.
Illustrative example

- Consider two robots (red and blue) maintaining their balance.
- Connect the tips of them by a rod (green).
- The red robot falls down purposely. (⇐)
- As a result, the blue robot falls and the red robot returns to the standing position. Can this simulate JUDO maybe?
