This robot is designed to pick up table tennis balls and it is not a kit. I completely designed and built it for a friend who plays table tennis. The front side of the robot has an opening in the corner of the concave angle formed by the two sides. There is a rotational door in this opening, which is activated by a couple of sensors located on top of the door. When the sensors receive a signal about an object e.g. like a table tennis ball, the signal is transmitted to a servo engine which turns the rotational door in 360 degrees hitting the object inside the robot as shown in image 3 and 4. The Robot can be operated in two ways;
1) By using a remote control, which permits the user to increase or decrease the speed of the lateral wheels.
2) By activation with a chip located inside the robot, which allows the robot to move independently and in a randomly.
Either way, independent movement or remote controlled movement, the robot will move on the floor surface and all balls which come close to the front will activate the rotational door and the ball is pushed to the inside the robot.
