End of the week (Accomplishments)

Gadgets and Changes

This week everything on our robot has changed with the exception of our chassis. Our original game design that we had, which shared similarities to basketball, has changed. Our new game consists of picking up ping-pong balls without using the pre-made VEX claw and then shooting them at red solo cups; hitting stacked ones yields more points. The arm and End of Factor design we had at the beginning of the week has been scraped. We now have a two piece mechanism in the center of our chassis. One piece is designed to pick up ping-pong balls an then place them in our "shooter" (the second piece). The first piece is a simple claw design that consist of two medium sized gears that are connected to 2 skinny metal pieces. They're curved and covered in friction resistant cloth. This will act like a Standard VEX claw. The second piece is like a scaled down tennis ball launcher made for ping pong balls. It has a very high speed compound gear ratio with 2 separate motors, each with their own large VEX wheels.
