Hydraulic Robot Arm Controlled by Human Arm

The hydraulic robot arm consists of two major parts: first is a human arm movement sensing and transmitting section, and the second is a receiving section and hydraulic robot arm. For sensing, linear potentiometers have been used and the voltage drop across each potentiometer is modeled. The control signals have been generated through CC430F6137 microcontroller and sent wirelessly. On the other end, the receiver captures the respective signals for the human arm movement, decodes it and then sends to the hydraulic robot arm control section. The innovative hydraulic control section has been developed to control the robot arm movement, in which both the suction and pressure mechanism is utilized for the robot arm actions. The developed system has been tested by operating from 200 meter distance by performing the human actions and observed that the robot arm performs a similar action as that of the human arm.
