well, look at evrything : robonova, 1000$ for metal and plastic 
bu is it possible for the actuators to stop in the midle and hold the position?
Why not use small PNEUMATIC PUMPS? LM shows how to creat one for dirt cheap!
no, i want to make an arm with some oomf
and thats wat im trying to figure out, i knowthat is can hold a position cause it has a pot in it
it says this in the description of the actuator so i assume that it can go to a postion and hold it, idk wat else a pot would be used for in an application like this
also if i use pnuematics, i will have 6 rolling pumps on board, 12 valves, it wouls just be too much stuff in there, crammed in with the battery packs the motors, electronics, just too much stuff
That’s a nice rover you put together. Makes me want to get off my lazy ■■■■. 
6-inch travel at 0.5 inches per second = 12 seconds to move half a foot.
“Oh, no! I’m being chased by a giant killer robot! What should I do?!”
“I don’t know - walk faster?”
lol, i know, but the rover it self will be going faster than that, ill just drive faster
besides, how often do you need an arm thats fast? i mean yea its be nice but it will go faster that that because of the place where the actuators are linked and everything andim not planning on linking it to the very top of the “bicep” to move it 
btw, has anyone figured out how and can send commands to the pot to get it to hold position?
