I’ve coached FIRST Lego League Teams since 2015. The team has their own website.
Something fun we tried after the season was over was a tug-of-war contest. I divided up the important parts (motors, weights, wheels) and “sold” them to the teams. So it was a decent lesson in economics, mechanical design, and physics (and maybe a little bit of fun)
Another interesting thing I experimented with was using medium EV3 motors for driving, instead of the more traditional large motors.
A few seasons back, some fellow coaches and I challenged each other to a contest. The rules were:
- you can use the kids’ robot, but must build your own attachments
- maximum time: 30 seconds
- you must do the gecko mission
- maximum build and programming time: 8 hours
