Automatic Lego Builder

This lego builder can build lego just by voice command. Like Auto Builder, it builds lego models for you but all you have to say is the colour of the brick and the two colour sensors at the back will search for the colour. Once it has found the colour it will push the cart holding the grabber with the motor underneath the cart and stop when it can grab the brick. Then the grabber will pick up the brick, bring it forward like the M.T.R.4 and place the brick on the conveyer to build the model!
