Re: Arms

For the last couple of years 27 has used no pneumatics (which is not related to the fact that we cant spell the word which would make our boards bad). Id have to say that it depends on what you are doing. For a one shot thing that has a straight line motion (Such as lifting) Id say it would be easier to use pneumatics. But the compressor weighs a lot. We had no where near the weight to put it on. Nor did we need it. If you have to have that motion in a line there are many ways of simulating it with motors.

Also positioning does come into play, if you were going to use it to position your arm over the legs... good luck. If you were just going to use a small cylinder to open and close your grabber, that would be pretty handy. Actually a motor is a more difficult choice in that case.

Really, it comes down to if the benefits offsets the cost in terms of weight. Pneumatics can be very useful but at the same time weigh a lot. Also consider that perhaps you dont have to use the compressor, you can use the tanks and just top them off. The final thought is that it comes down to personal preference, in our situation it wasnt required and could be done easier or more efficiently with motors.
