SACC-26 (Servo Arm with Compliant Claw and 26 inch reach)

thingiverse

This Robot is designed as a high school robotics project to teach students how to design, build and analyze a robot arm. With 9 inch long arms, this robot has a horizontal reach of 21.8 inches and a vertical reach of 26.8 inches. This impressive reach is achieved through the use of a low-cost GT2-6mm belt system. The robot can manipulate objects weighing up to 10 oz (¼ kg) with readily available 25 kg-cm (348 oz-in) rated servo motors. The estimated reach assumes a 140 degree servo range, even though many are rated for 180 degrees. The total time required to print the parts is approximately 38 hours using a 0.2 mm layer thickness and will use around 0.45 kg of filament. The cost of the arm alone, excluding a control system or servos, is around $40. The recommended servos are priced between $100 to $200. The FTC control system includes two android phones, electronics modules and gamepad, and costs approximately $400 (teams typically receive grants and discounts, so this number may vary).
