Let's Make Robots!

which motors do i need?

Hello,

I was looking for a new challenge in building robots.

The new robot is 100 kg and needs 4 motors. I am a quite noob with motors. 

i used this website to calculate the torque needed for the motors

http://www.robotshop.com/blog/en/drive-motor-sizing-tool-9698

but the problem was that the outcome was that I need 4 motors of 30 Nm. I think that is very much and i can't find motors of 30 Nm

can anyone help me with this problem?

 

Thanks a lot
