Robot Arm

Robotic Arm | Projects

  • The robotic arm has three joints: a “shoulder”, an “elbow”, like ours, and a “hand” at the end of it. The arm is placed on a rotating base, so we could turn the whole arm 360 degrees.

    The part of the arm that connected to the base was straight up and down, but had an important function. It would raise and lower the arm. This enabled the next part of the arm to raise and lower the rest of the arm; for precision work. Finally, at the end, was the hand. The hand was a linkage that was connected to an actuator, so when the actuator pulled back, the hand would close as to grab something. All of the actuators were wired up to an arduino with a R/C shield, which allowed it to be controlled by a remote control.
