Robotic Arm

This is my first "big" prototype project ever made with my ender-3. I think it looks cool. As I said, its my first project so it isn't perfect. But it is still a fun desktop toy to play around with :p

If my semi fast torque calculations are correct it could carry a load of around 140 g on the end of the fully extended, horizontal arm (wich is 40 cm with a gripper of 20 g and a length of 5 cm included). But this quickly rises as we make the working distance smaller.

parts printed:
-2x arm_part
-1x shoulder
-1x grip_connector
-1x upper_plate
-1x ground_plate
-8x cilinder
-8x spacing_cap

motors used (edited):
- 1x servo motor (20 kg/cm). tower pro MG958 could be used.

- 1x Tower pro MG-996 (for the first part of the arm)

- 2x Tower pro SG-5010 (bolted on the bottom of the upper plate and the arm with the gripper connecter)

screws used:
- For the motors I use the screws that come with the motor together with a printed screw spacing cap.
- The horns, I drill
