Yellow Drumming Machine with Drumsticks

The project produces a 4 wheel cart robot which can detect various obstacles using IR sensor while being equipped with a couple of drumsticks attached to servo motors.

In the design, two drumsticks and a doorbell were used for some ticking sounds as the robot will start drumming once it founds an object. A total of 9 motors and servos are being used by the robot where 4 modified servos are used to drive around and navigates using a single IR sensor on its head. For the drumsticks to move up and down so that the robot has free visibility, an extra servo was used.

A menu for all functions can be seen on an LCD which can be used for drum function such as random, choose drum pattern, while driving or standing still. It also has voice control using Dragon Naturally speaking on the laptop. The remote control operates at 433MHz and is controlled by a laptop using a Visual Basic 6 based gamepad. The IR sensor used for driving around consists of 1 IR LED and 1 TSOP 1738 IR receiver. The two PIC controllers are the brain of the robot.
