Lego Robotic Arm

This is a model prosthetic arm made entirely of Lego.

-hand movements and wrist abduction/adduction are Lego pneumatics
-wrist pronation/supination, wrist flexion/extension, and elbow flexion/extension are Lego motors (Power Functions)

The main purpose of this project was to accurately mimic the full range of motion of a normal human arm and hand. The secondary goal was to maximize speed and power, yet maintain a consistent ratio between the two for demonstration purposes. It is important to note that it was designed as an above elbow prosthesis, and the yellow shoulder is only meant to act as a static model.

The amount of weight it can lift is limited to the shape of the object and orientation of the wrist and elbow, but it can't do much with more than a couple pounds.

The controller is a rudimentary cluster of switches and joysticks. A 4-motor air compressor with pressure-regulation was made of Lego, but for the demonstration I simply used hand pumps.

Enjoy!

Fap fap fap hand

What all things are required to make things ?????

Пиздец

I did something similar using lego pneumatic. The main disadvantage is that it is slow, very slow, and not so precise. I converted to servo motors and cables afterwards: try it yourself!

Watch this guy.He will be building Terminators someday.

Dude ur awsome

[splicer0407]

If I ever get my arm lopped off...

[drift419]

kinda makes ou think that lego is more advanced technology than most things in the world you can basicly make anything out of lego if you can put your mind on to it

to quote big bang "All you needed was the hand" XD
