The techniques described above would limit the maximum speed of the robot, but it sounds to me like you want a mode that would decrease the sensitivity of the controls at any range. I would take the PWM signal, subtract 127 (so the range is -127 to 127, not 0 to 255) and multiply that new number by a constant, say .5. I would then add 255 to this new value to get your new PWM signal. The robot will now be half as fast, and half as twitchy.

Shouldn't that be a 127, to bring the scale back to 0-255?
