The main aim of this project is to design and develop a tree climbing manual control robot in which control by using radio frequency (RF) signal. With the RF control, the movement of the robot can be much easier and not too limited because it is not attach to a wire. The objectives of this project are as follow: 1. To design and develop a robot that has capability to climb tree and control by a remote control that using RF as the command transmission between the robot and the remot. 2. To modify a RF circuit from a normal control car toy and integrate to the robot mechanical system. 3. Able to receive and send command signal between the robot and the controller by using the RF signal. For future development of this project, this kind of robot can be develop or modify so that it can help human .
