Robotic arm modelled after open source uArm
grabcad
The robotic arm, inspired by the open source uArm, can be produced using a 3D printer. It replaces the servos with 28BYJ-48 stepper motors and adds a gripper operated by a servo. The stepper motors are altered to run as bipolar motors for increased torque. Other enhancements include the use of #6 screws instead of metric ones, and hinges made from 1/4" nylon spacers.
