... ratio changes. The elements of a reflexive muscle force (steering torque) control loop do exist in the human NMS, in the form of Golgi tendons that send information on muscle force to the motor neurons, but little is known about this control loop ( 22 ). Doemges and Rack ( 16 ) showed that displacement...

The proposed joint controller can be efficiently incorporated into any robot motion control system based on either its torque control interface or the virtual decomposition control approach. Experimental results demonstrated in both the time...

In this research, a distributed nonlinear damping controller using backstepping techniques for wheel-torque control is first developed for single-axle unicycle type robots. The controller is then extended to multiple-axle CFMMR configurations and is robust...
