Hey ya'll, still working on the VRbot (Admin's Instructible). I got it working correctly, but I had not known you could modify the servos for continuous 360 rotation, so it had limited movement.
To make this modification, I followed various online tutorials, where each one had slightly different procedures dependent on servo type. Mine are HS-311's.
After taking the cover off and unsoldering the control circuit from the motor, I disconnected the servos potentiometer, soldered in two 2k ohm resistors in it's place, chopped the "stopper" thingy on the restricting gear, and buttoned everything back up.
This VR bot requires two servos: controlling left, right, forward, and "dance" motion commands. Since my modification, Every command registers as "left". I get very full, fluid motion in the left direction, but for EVERY command. Meaning, both servos (left and right) are rotating clockwise. Before the modification, the servos at least switched to the appropriate directions depending on my vocal command.
Can anyone tell me what I may have done wrong in my modification?
