Robot with Wireless Color Camera

Need a spy robot that give your laptop an eye and information about remote environment condition? You also will need to control and get those all data wirelessly. This is a project about that.

The main parts of this robot are:
1. Chassis from remote control car toy (4WD)
2. 2 DC motors for wheel
3. DC motor driver using H-bridge
4. 1 mini stepper motor to rotate camera
5. Stepper motor driver using 2803
6. Controller using ATTiny2313 microcontroller
7. Wireless color camera
8. Transceiver 433 MHz
9. Radio AV Receiver
10. Batery pack 9V

This robot get real time view from wireless camera, and controlled via laptop . The control actions include moving forward, backward, turn left, turn right, rotate camera (cw and ccw) . The distance between robot and control station (laptop) depend on the max distance of tranceiver which is 100 m in this project. The program done in C using CodeVision AVR for microcontroller and Visual Basic for user interface in laptop.

Legged Robot Hexapod

This is a project to make six leg robot (hexapod bot). Legged Robot has higher difficulty level of design and programming than wheel robot. Hexapod bot imitate the structure and movement of insects.

The main parts of hexapod bot are:
1. Chassis
2. 12 servo motor 180 degree (2 servo/leg)
3. Controller based on AVR 8535 microcontroller
4. Battery pack 6V DC.

Beside that, range sensors such as ultrasonic or infra red could be attached to the robot to have more sophisticated function of robot in the real application.

In this project, the hexapod bot do a simple maneuver/movement, moving forward, turn left, turn right .

The program done by C language using Code Vision AVR.
