If your into Robotics and don’t limit yourself Strictly to LEGO® building elements, Rokenbok’s new “Maker Rok” vehicle (which I prefer to call Rok-Bot) is very versatile. These are two of my own designs, each took less than a couple hours to make. I made this first design to lift and dump the little balls at really tall heights. It was inspired by a CG scissor lift design of another Rokenbok forum member, and uses only the Maker Bot’s included parts. This second design is inspired by a really old K’nex robotics set I bought years ago, which has a very versatile mechanism for picking things up. .
