WebThere is a lot of work associated with robotic or prosthetic arms, devices which need to bend and move – for which actuators are needed. Most industrial robots are based on gears and continuously rotating motors. However, just as some sensors can be inspired by nature, as in echo location, so are some actuators. So let’s consider the human arm and hand. WebThey used electrodes to pick up muscle activities in the arm and replicated the motions in the robotic arm. Two electrodes were used and two joint motion was enabled . Shamsheer developed a robotic arm using sensors and microcontrollers. He used ADXL335, a 3-axis accelerometer sensor, L3G4200D, a 3-axis gyroscope sensor, and flex sensor.
