Using these dolly wheel drive plates is quite easy. First, get 1” - 2” OD aluminum tubing or PVC pipe from your local hardware store. Then, assemble the plates according to the instructions. Remember, each fully - assembled plate can hold up to 150lbs, so don't overload it. When using the plates in an Actobotics system, take advantage of the standardized hole patterns to connect components. For maintenance, regularly check the plates for any signs of wear or damage. If you notice any issues, replace the parts as needed. Store the plates in a dry place to prevent rusting.
