Catapult and Ball Hunting 2

Design Problem- For this assignment we are required to design, build and program a robot that catapults a ball as far away as possible and then finds the ball and stops when it touches it.
Solution- After playing around with the Lego program and our robot, we were able to create a program that will catapult the ball but we do not yet know how to program it to look for the ball and follow it.  The only thing we know is that we need to use the ultrasonic sensor. Because most other groups have been having the same problem, an idea of using a remote control has been proposed. Thanks to the advanced technology we are able to download an application onto a call phone and use it to control the robot.  We can make it move forward, backwards, right and left. This technique seems much simpler than programing it. 
Experience- After working for a couple hours on trying to program the robot to complete the given task we were only able to create a catapult but not find the ball. When we came into mentor session today we were surprised to see other groups using their cell phones to control the robot. We thought this was a much more efficient method and are currently working on downloading the same application for our robot!
