$80,000 grand prize were these guys, from the australian centre for robotic vision at the queensland university of their laboratory, i expected the customary conservative welcome from the usual studious scholars. robot: 0k. let's go and see cartman. after you. how fitting that an award—winning robot should have its own bot butler. all of these robots require some degree of specialist knowledge. so if a particular specialist is not there on the day it is really hard to get the robot to operate. whereas, pepper, anyone can pull pepper out and start running the robot. if you want to see cartman in action, select an item on my screen. let's go for the marbles. hey, ca rtman, please fetch the marbles. a robot is telling another robot how to be a robot. cartman has three axes of movement and works like an arcade crane claw. but, he has two hands. a suction grip and a pincer. he chooses which one to use depending on what item he needs to pick. there are many different ideas that we brainstormed and prototyped and engineered and finally this is what we came up with. this is the one that won the challenge.
