My robot will have two touch sensors. It will go forward and touch the first billiard ball which will activate the arm which will trap the ball. The robot will reverse and take the balls to a pocket. IT will repeat these steps until there are no balls left. The arm is capable of taking at least two balls. Since the arm I am making is to weak to actually lift the ball, it will trap it with a lasso and take it to the pocket. This will take place on table. If the robot goes too fast and hit a ball over the table, that ball is dead. If the robot falls off the table, then that person will move the robot to the starting point.
The first picture shows what kind of car you are going to use. You start with a basic tank bot. Then you add a touch sensor to the front which is shown on the second picture. The third picture describes the structure of all the gears that will connect to the lasso. The fourth picture shows the lasso which will later be attached to the top of the touch sensors.
