Kids have been testing their robot programming skills in a competition at the Science Museum in London.
It's the first competition in the UK for robots programmed by kids.
Each of the 16 teams competes with the same type of robot. It's how they programme them that makes the difference.
Kicking a football into a net was one of the skills the judges were looking to test.
Another test was the zipline. The robots needed to keep hold of the cable as they slid down.
Even dancing was tested. Which robot could bust the best moves and shapes to the Scissor Sisters?
The teams were allowed to change the way their robots looked as well. Check out this one's blinging necklace!
There were two winners on the day. Langley Park School took the Dance-off with Bob, while Kingston Grammar School won the assault course with Dirt.
