Re: Legal Camera Pan/Tilt Mounts?

While we are on the subject, please remember that the camera mount is electrically tied to the battery return line (i.e. negative terminal of the battery) through the camera power cable. This is one of the common ways that the frame of the robot is tied to battery. Be sure to insulate the mounting somehow to prevent an electrical fault to robot frame.

<R43> All wiring and electrical devices, including all control system components, shall be electrically isolated from the ROBOT frame. The ROBOT frame must not be used to carry electrical current (e.g. this is necessary due to polarity reversals that occur under certain operating conditions such as during motor direction reversals).

The chassis for the cRIO-FRC and the supplied KOP camera have grounded enclosures. Under this rule (and for their protection), it is REQUIRED that they be electrically isolated from the ROBOT frame when installed on the ROBOT.
