5 DoF robotic arm is driven by stepper motors with mounts for hall-effect sensors. This robotic arm is a derivative of the Annin Robotics AR3 model but has been modified taking into consideration that it is fabricated by 3D printing.Bearings used:J1 Turret- 32009 (45x75x20mm) taper roller X 2J2 Turret- 30206 (30x62x17.25mm) taper roller bearing X 2J3, J4- AXK3552/AS3552 (35x52x4mm) thrust bearing + 30204 (20x47x15.25mm) taper roller bearing eachJ5- 605ZZ 605RS X 1Pulleys-J1- GT2 120-20J3- Sprocket 1-1J4, j5- GT2 60-20Holes are sized for corresponding 3d print brass inserts.
