Today we mainly worked on prototyping ideas for picking up balls and crates, but we also brainstormed some ideas of how to deliver magnet balls to the off-field goals.
One of our prototypes, nicknamed the "tomahawk," was thought up by our mentor Mr. Pahle. It consists of a fixed plastic plate, along with a plastic plate that opens and closes to grab a crate. We programmed the tomahawk to open and close, then tested the prototype. We discovered that it can actually lift a crate, and now we're working on attaching it to a motor and an arm. That way, we would be able to grab a crate and lift it, keeping it level all the time.
We also worked on rebuilding a conveyor belt from two years ago, which we could use to pick up racquetballs. Of course, we are only allowed to hold fifteen balls at a time, so our conveyor belt might be too big at this point. We were also considering mounting a magnet sensor on the conveyor belt and using the sensor to control a flap. The flap would control the racquetballs, sending the magnet balls into a special container and the regular balls into a different area of the robot.
