DTMF based robotic arm design and control for robotic coconut tree climber

摘要

This research work focuses on wireless controlled robotic arm using DTMF (Dual tone multi frequency) technique. The arm is designed to be a part of a coconut tree climbing robot. As the number of human coconut tree climbers is dwindling, there is a dire need for a robotic climber. The robotic arm is capable of a two axis rotational movement. The entire robotic arm can be controlled by using a remote device - mobile phone which hosts the DTMF Technology. The remote device can be used to control the movement of the arm. It can also be used to control the direction of rotation of the armatures. The use of DTMF technology for wireless transmission gives an edge over other wireless transmission techniques as the former incorporates a much better range for the transmitter and receiver.
