Hi,
     I am building a robotic biped and am trying to preprogram the
     sequences of motions by a 8052 microprocessor. However, I
     discover that the leg will be off-sequence when it walks
     for several steps. I just wonder I need to add a feedback
     circuit to it so that it can adjust itself automatically.
     However, I don't know really how to build an economical
     feedback circuit since I need it/them to control 6 to 7
     motors. The method that I control the motors is by controlling
     the on/off time of the motors.

     Please tell me if you have any suggestions and I will very
     appreciate that.
