Im looking for an arm to use in a marketing project. Im not very experienced in electronics but from looking over the various arms it looks like I would need an AL5D or possibly AL5B. Unfortunately the D-version is sold out and I can’t wait for mid July so I guess I have to go with the B version. I am having trouble seeing what the main difference is but it seems mostly to be the size? Please correct me if I am wrong.
Also, the main use of this product will be to serve a drink, or perhaps mix a drink from 2 or more fluids. For this I need to also get the “Wrist rotate upgrade” right? In order to tip a can for instance?
How strong is the arm? From the picture it seems like it could lift at coke can at least …
Also, we are going to hook this up to one of our radio remote control systems and forego the use of a PC. This should be no problem I guess - that has more to do with delivering currents to the servos. Again, pardon my limited engineering skills. But we managed to do it with one of these: youtube.com/watch?v=Zg3qd7utejw&feature=player_embedded even though its a much simpler design.
The arms on the website are not built for strength. Rather they are designed with economy in mind. The small arms use low power servos and the large arms use stronger servos. What I would do is buy brackets for the 755/5745 servos and make the smallest arm, (shortest length between axis points) you can. By making the arm small but using the large powerful servos you are maximizing the payload capability. Look over the assembly guides for the arms to get an idea on what brackets are needed. lynxmotion.com/ViewPage.aspx … egoryID=19
For the best results you would need the 5745, but Hitec dropped the ball and we have to wait till July for them. Actually I have been wanting to do this too. 8) Hope this helps.
Be aware that the arm in the video and the lynxmotion arms operate a little bit differently (geared motors vs servos). If you use an RC tx/rx with the lynxmotion arm, you should be able to duplicate the controls.
If by “it” you mean the AL5D, then no, I doubt it would lift a full can of soda elegantly. As I stated I would use the servos from the D arm and reduce the size. This will make it very strong. As for the wrist rotate it depends on what you want the arm to do. Do you need wrist rotate?
Yea, the idea was for the robot to be able to pour someone a drink, or maybe even do a mix drink from a few different containers. Hence the need for some strength and the ability to wrist rotate (pour)
