PnP is a very simple (but flexible) LEGO robot that mimics some of the things an industrial robot can do. The arm is very basic, but can address a large workspace using two-axis spherical motion and a parallelogram mechanism to keep the “finger” level at the end. Using NXT-G and the LEGO NXT motors gives it a high accuracy, enough to place 2×4 bricks within a few millimeters of the desired position. The result is that PnP can move simple objects, and a wide variety of “work stations” can be fitted around it. It can also firmly push on things, activating levers or sliding mechanisms. Since the NXT can easily drive at least one more motor, this minimalist mechanism can easily be expanded.
This was inspired by Ian Hendry’s amazing LEGO creations, and another project that seemed to require linear motion… but I wasn’t sure it did.
