Backlash Disadvantage 0f Dynamixel RX-64

2008-02-07T12:47:46+01:00

We are designing a mobile robot and need high torque & high accuracy actuators.After some researches we knew that Robotis DX & RX actuators are nice and support our requirements, but we wanted that use your experience & knowledge in using those actuators in your humanoid robot, where the high torque and accuracy is needed. Then I wanted ask you:

1) What is Disadvantages of those actuators?

2) Do they have these Disadvantages? and if Yes, how you solved it??

- significant Backlash (how much was it???)
- overheating in limited usage
- breaking of gears on heavy loads
- significant friction phenomenon, including "stribeck" effect
if you know about BACKLASH of RX-64 and the way of solving it, plz guide us.

Thanks a lot,

Never miss a thing. Make Yahoo your homepage. ? and if Yes, how you solved it??

3) How you supply actuators with Li-Polymer batteries, where they need high voltage (16-18v) and Max standard voltage of mentioned batteries is 14.7 v?

Thanks a lot,
