Blaah no time to work on my robotic arm but i may change my wheels into treads or multiple sets of bike sprokets w/ chains for the treads i'm thinking one will be to small so it may take me a while to gather multiple sprokets and chains. My robot is kind of unique in so far i've paid for nothing, call me a garbage picker, but everthing has come form the side of the road. which proves difficult to find a power supply.
The next step is to find a job for the arm and hopefully i'll have learned enough in my electronics class to make it autonomus. the ultimate test.
