We went to the county fair. We saw tractors. We saw somebody on a bike scroll saw. It looked like a scroll saw with bike pedals. It didn't have a blow tube. It had a plastic card that moved when the arm went up and down and cut. It blew the dust away. The saw cut really smooth.
We went to see the robotics obstacle course. It was where the horseshoes usually are. We expected to see men throwing horseshoes, but they weren't. They had different robots that were supposed to be able to do the same things but looked a lot different. I think Robot 1 and Robot 3 were almost the same and went up on their back wheels the same. They had back wheels and front wheels that went up. Those weren't the powering wheels. And then when you stopped it, the wheels were still up. And then when you lowered the wheels, it goes back to normal. There were 3 robots. Robot 2 had caterpillar treads.
