My goal is to build a small crane; no bigger than what will fit on my desk.
I have the LEGO nxt 2.0 set, and have tried a couple of solutions, but when lifting, it puts way too much strain on the servos, obviously.
So, I wanted to ask the forum, what would be the best/cheapest/easiest approach. At the moment, I am looking at pneumatics, since it is safe and the concept makes sense to my inexperienced person, although, as far as i've gathered, the parts aren't exactly cheap.
Oh, and probably worth mentioning, the crane is more like an arm. Im imagining three jointed, where the first joint is at the base, and the third is at the very end, where the hand is. It should have a grabbing hand instead og a string with a hook.... So more of an arm than a crane, I guess.
