# What servo motors do I need for lifting at least 10 pound of something and hold it in place? [closed]

I am very much new to robot building. I am building a robotic arm for a everyday use. Basically, it will be used to hold and position a yard tools while the tool is being used and will be controlled using remote control. I have already bought the brackets, but now I need to buy servo motors; Not sure which or what servo motors to buy. My yard tool weighs about 10 pound. So, I need to know the name and/or brand of servos I will most likely need. Any hints or clue will be highly appreciated. Thank you.

• Servos are usually rated for torque. At what distance from the servo do you want to hold the tool? For example, if you want to hold the tool 1 foot out from the axle of your servo, you would need a servo rated at 10 foot-pounds. That's a big servo, by the way - most hobbyist servos are rated in ounce-inches. – rcv Oct 9 at 20:49
• I should have mentioned that I am also going to need 3 servo motors. The tool is going to be about one foot away from the servo motor. Well, I don't understand what you mean "BIG MOTORS." Then, what do they mean when they say servo motor rated for 10kg-cm? Isn't 10kg = 20lb? – ThN Oct 9 at 20:58
• How high are you going to lift it? The greater the distance, the more powerful a servo you're going to need. – Tanner Swett Oct 9 at 22:23

• @TannerSwett the highest it will go up off the ground is 6 to 8 inches off the ground. – ThN Oct 10 at 10:25
