I use pololu.com power hd servos for the heaviest loads. They handle 240 oz in torque. You could use servocity.com gearbox to multiply torque. I have the 5 to 1 gear ratio using the pololu servos to get 1200 oz. Of torque.. you can buy just the gearbox kit and use it with your own servo. It costs twice as much to buy it premade.

Hello can anyone please tell me if that is possible to achieve position feedback with esb as shown in the dynomixel demo? If so how? Is it posable with encoders? That would be so usefull

Ezrobot has a different feature called the "record" option. Because rc servos have a pot and control board built inside it doesn't send feedback to the controller. You could mount pots on your joints and use adc ports to read their position but the record function works just as well.

When I get some free time I'm going to have to design an inline pot/ servo holder to fake it. Of course I im going to post the file for everybody who has a 3d printer. I think it would be cool. The only issue is the amount of pots the ez robot allows.

Lol im amazed at how many people have 3d printers

What is the strongest servo that is compatible with EZ-B?

@Jstarne1 I purchased my printer in January 2010. Back then you could Call Bre Pettis up and talk to him directly at Makerbot. I was Makerbot #790. Now you will be lucky if he answers an email he is so busy. They are close to 100,000 bots now.

Rashad Hello! any RC servo supports ez-b, if the high torque servo is better to use separate power, personally I like these servos, very strong and cheap:

Certainly I like your idea of ??building robot arms with foam, maybe a thin aluminum coating would make it more resistant.
