Robotic Arm Controlled Romotely


This is a Robotic Arm built by [david21n] which is contolled with a 1:1 controller that has the exact same structure.

Remote Controlled Robotic Arm

The robotic arm is basically 4 standard servos and three micro servos. All the mounting parts and
turn-table is from lynxmotion. The other parts are made from cut pieces of polycarbonate and PVC angles.
The microcontroller is an Arduino. I used the Ardweeny from Solarbotics. There is some electrical and
duct tape on it since the cut poly carbonate has sharp edges.

The controller is made of PVC angles and potentiometers. I made the controller like a 1 to 1 model of the
robot arm. The joints are potentiometers. I used servo cables to connect the potentiometers to the
microcontroller.

The microcontroller would read the potentiometers and control each servo. The controller has really
fine control, but the potentiometers are not perfectly linear. the potentiometers need to be calibrated in the programming.
