Robot diplodocus hedge cutter

This invention would really help people who can't use heavy hedge trimmers. I've had a go at making it in cardboard. I looked online for pictures and I modelled the shape on a diplodocus and used a chainsaw for the tail and secateurs for the robots mouth. I added to Oliver's design by adding caterpillar tracks so that the hedge cutter doesn't get stuck in mud. I started with a pre-made box and built the grinding stomach by cutting loads of cutting disks and threading them on to a tube. I made the tracks by peeling the top layer of paper of the corrugated card to give it the texture of a caterpillar tread. Oliver's robot has two heads I like how the secateurs look like a mouth and and eye of the robot.
