Im in a competition and we need to build a robot that shoots 3 ping pong balls through 3 holes and then rounds the bases as if on a baseball field- there is a peg at each base it must knock down. Heres a link that shows the track on page 3: http://www.tcc.edu/faculty/webpages/pgordy/ASEE/ASEE2010/ASEE TYCD 2010 Rules _10-14-09_.pdf" We have 3 ideas so far 1. have the robot run in a set circle that will knock down all 3 pegs in its path 2. Set up some type of sensor to measure the distance the robot has travelled and program it on a path that will knock down the pegs. 3. Use some type of sensor to keep the robot on the black tape on the track. Which idea do you think is best and how would we go about implementing one of them? Also what are some ways to propel the ping pong balls into the holes? The robot must do this all on its own after we start it, we cant have any remote controlling.
