Need help with a project!

[piemazter123]

Basically I need overall help with a... erm device. I decided a robotics forum would best suit my needs hopefully it will. Essentially I need multiple servos capable of moving around 100-250 pounds. What kind of servo would fit that description?  I'd also like to say smaller is better but I also only have a budget of around 15k for servos alone. If I counted correctly I need 6 servos with that kind of power. This information would greatly further my progress in my project. Sorry I can't give more details on what I'm making, if it gets out of the prototype phase, which will take a while, then I could show you guys something from science fiction and be able to call it science fact. Please help.

Edit: These servos need upwards of 45 rpms

Cool! Maybe I can offer an opinion......
Are you using wheels, the demand will be different from a walking model.
IF YOU ARE making a walking model, I would offer an idea in that direction. I have
been working on an inexpensive way for robots to walk, and does not require
a million dollars to program. Still in the proto stage myself.
I have found out that, the wheeled robots are easier to program than the
walking ones, with balance and direction to take into consideration.
The walking structure that I use is simple(relative), and less expensive. I designed it
to do work, in the expectations of a human counterpart. With simplicity, comes less
programming headaches. --

You need to provide either a radius, linear speed, or torque. You have provided a rotation speed and a linear force but no way to correlate the two.

Also provide as much information as you can. I understand you may not be able to share what you are producing but I'm sure you can share more specifications. for example what are the power or control requirements for these servos.

  Hello!
bdeuell gives good advice.
In reference to you seeking servos, I wold recommend looking at the Thomas Registry. It
has all the manufacturers in North America. Any parts or subcontracting can be found.
Good luck!
