Torso Knob

Bar KnobThe selector knob that is used on the B9 robot’s torso is available commercially. Click here for the full specifications. Here are a few places on the web where you can get one:

Many people use the knob to control a function on the robot by adding a switch or potentiometer behind it. Volume control is one popular use, but I installed a rotary switch and use the knob to control the various lighting effects that Tom Wisnionski’s light controller provides. The Brain Lights page has more about Tom’s controller, including a short video.
