The HS-225MG and HS-645MG combination sounds good. The other 5990TG servos are really expensive. I think I will slowly upgrade to 12 5990TG servos over time by replacing 1 of the HS-645MG servos at a time.

I'm not sure if I am getting the right PS2 controller. I need the wireless one. Are there any other parts I would need to get to make the that PS2 controller 2.4ghz and control the hexapod?

Am I missing any other parts?

Hi, You won't need this part:

And you will need a cheap PS2 extension cable, which you need to chop/hack in order to add a PS2 socket to the HexEngine. There is a wiring diagram for this in the HexEngine user guide, however, wire colours vary, so you need to use a continuity tester to check you have the correct wire on the correct pin.

Most PS2 controllers work at 3.3V, see this thread: http://www.hexapodrobot.com/forum/viewtopic.php?f=14&t=178

I corrected the parts list and removed the RJ11 connector. I added the psp cord. Where is a good place to get a continuity tester? I don't have one.

Not wanting to chuck a spanner in the works, but i found that particular PS2 controller to be a bit hit-n-miss.
Well actually, much more miss than hit.

I went through three of them - exactly the same controller, different brand and never got one to work with my hex.

The Logitech wireless i now use has been great (once matt figured out that it wanted 3.3v ;) ). The transmitter bit is a nice small unit and once attached to a short extension cable it'll all fit neatly under any additional control boards (BB2) you might add.

Just a thought.

I agree, I tested plingboot's Logitech unit, it was by far the best I have used.

I'll use the logitech psp controller you suggested plingboot. Are there any other parts I need to get the logitech controller to work with the hexapod other than that psp extension cable?

I had originally just searched for a 2.4ghz psp controller and that psp controller combo was the first thing that popped up. I guess I should have done some more reading on it first.

Are those the only parts I need? Nothing else for the PSP controller right? I want to order the parts this weekend. :D

No that should do the tick, maybe some batteries for the wireless game pad :)
