I posted this in another area of the forum, but I realize it fits better here.
I am currently designing and getting ready to build a small hexapod, very similar design to the ones I’ve seen on this board, but a bit different. In total it will have 14 servos, 2DOF legs, webcam, distance sensors, foot pressure sensors, etc…
My question is about the servo’s I am going to use.
I am looking at using the HS475HB servos (76oz-in) but I wonder if these may be lacking a bit of torque so I am thinking of using 645’s also.
The 475’s will control the leg swing, which is supported seperately by bearings, so the servo should not get worked too bad.
the 645’s will do the heavy lifting of the leg, with the lexan leg mounted directly to the servo horn.
The 645’s are out of my budget but a local hobby shop is going to give me a pretty good deal so I can swing it.
Does this sound like a decent plan? do you think this would be too much for the 475’s to handle alone?
I cannot estimate the weight of the robot, but it is mainly the weight of the 14 servos, controller, and battery. Overall this is going to be about 6"x7"x2".
For the controller I have a CMU Qwerk, so I plan on making this tele-operated via onboard wi-fi, and controllable via Ipod Touch and/or laptop.
Will these servos have enough torque based on what I’ve said? Any suggestions?
I have a bunch of pictures of my Inventor model, but the forum will not let me link since I dont have many posts.
I can email them if it would help.
Thanks for any help, I am going to place my servo order tomorrow!
