Possible Shield Requirements Analysis

What about at least one LED on the board to check the live status.

All robots with legs have the problem that the legs can be blocked by it self or by any kind of external forces. This is what we should detect to avoid any kind of damage.

For this we can check the rotation of the crank or the motor. If it will not count after a certain amount of time something is wrong and we should stop moving.

The best thing would be to have a current sensor for each motor or at least for the complete unit. I have this one in my quadrocopter but it is quite expensive and we don't need to monitor such "big amps"... CIRUS Sensor
