Robotic Arm 2 Degrees of Freedom Assembly Guide

Off

The Robotic Arm 2 Degrees of Freedom is a robotic arm kit that offers a manipulator claw and bracket made in aluminum. It has two degrees of freedom, one is for controlling the arm, the other the rotation of the arm. The kit is also easy to construct, and could be done by yourself.

HARDWARE SPECIFICATIONS

  • Full aluminum alloy
  • Supports 2 degrees of freedom
  • Maximum clamp opening – 54 mm

PARTS LIST

For this assembly guide, we will need the following materials:

  • SG5010 Servo Motor – https://www.bitstoc.com/product/250/
  • Robotic Arm Kit

ASSEMBLY

Prepare the following parts below. These parts are for the base of the robotic arm that will house one servo motor for rotating the arm.

Align the top holes patterned like a “t” of the servo motor holder to the base’s equivalent “t” pattern. Place the bearing between the two aluminum pieces, in the center hole of the “t” pattern. Place the larger base of the bearing in front of the servo holder, while the smaller base facing the base holder.
