Messiahs: Technic Lego Arm V.2Built this 2 years ago, I'm very proud of it, it's very strong, and can actually pick up things that are really heavy.. Big Lego wheels and so on. This is the second version of my Lego robotic Arm. This version is configured to move a bit more in every angle. This version is also green, the first one was black. It can pick up things all around it, where ever it's dropped. The controller took me days to complete, it has 3 Polarity switches, the previous version just had 2 (I had to order 1 new from Germany) It's very comfortable and if the batteries would die - it's very easy to change them. I only have e picture of the old preumaticpump, but later I actually built a compressor that pumped air constantly to an Airtank.
The whole build looks very simple, but trust me, it isn't. IT can move up and down, in 2 angles, turn around 360 degrees, grip, realease, and the arm is even capable of turning, not only the whole thing, THE ARM IT SELF (pictures below)
An older version:
The basic Idea, that evolved into Technic Arm V.2 (don't mind the text on the pictures, it's V.2 and V.3 of the OLD ARM)
