Robotic arm modelled after open source uArm
grabcad
This robotic arm is modelled after the original open source uArm and was adapted to be printed on a 3D printer. This model uses 28BYJ-48 stepper motors instead of servos, and adds a servo-driven gripper. Stepper motors were modified to run as bipolar motors for extra torque.Other modifications include adaptation to using #6 screws instead of metric screws, and hinges made from hardware-store 1/4" nylon spacers of various lengths.More details, code and pictures on this web page https://sites.google.com/site/eyalabraham/robotic-arm.
