Using these dolly wheel drive plates is a breeze. First, pick up 1” - 2” OD aluminum tubing or PVC pipe from your local hardware store. Then connect the Drive B plates to your motor and the tubing or pipe. Since the plates come in pairs, make sure to install them correctly for a balanced drive system. When using Actobotics components, you'll find it super easy to connect them due to the standardized hole patterns. Just align the holes and join the parts together. As for maintenance, keep the plates clean and free from dirt and debris. Check the connections regularly to make sure they're tight. If you notice any signs of wear, replace the plates promptly. And always refer to the SketchUp Part and Product Page (585536) for more detailed information.
