Squirrels & robot control
Squirrels use very fast balancing corrections. Why is this? Some
possibly relevant issues:
- Fast corrections (high acceleration) are relatively independent of
gravity. I.e. this is a "pulse compensation" as compared to a
continuous control process.
- They have litte mass m, which means that they don't need much
force F to get to high acceleration a = F/m.
- Fast pulse compensation is also present in eye movements.
Apparently for the eye, tracking is more difficult than focusing
on the same point for a longer period of time.
