@R2D2, The R2 stuff is very strong. I lift weights and consider my self a strong brother and one of my Robot arms are unbend-able (almost). I'm going to be using it for all my prototypes from now one. Best of all its not brittle or flaky. I guess that's why they use it for houses because they know it will stand the test of time. I also own a Vinyl cutter put a ball point pen it to make all of my templates. With a Hot wire you make all types of stuff and I don't have to pull out my CNC or 3D Printer. By the way IRobot is my favorite movie, I even own the 2004 leather converse and the same leather jackets and pants he wore in the movie. At some point I'm going to purchase a white R8 Audi (God willing).

Servo Link

These servos should work for your prototypes.

For some reason eBay says that item doesn't exist. Why don't you copy the specs and title and past them as auctions only exist for so long.

I found the manufactures site for those SM-S8166M servos @R2 was speaking of. I couldn't find prices there but all of the specs are available. May be worth looking at. I'm really new to robotics and don't know every technical aspect yet but I see they have 'Robot Servos.' I'm pretty sure I know the difference between analogue and digital servos,(Digi = 1/0's and analogue = Voltage) but what's the deal with these 'Robot Servos'?

They seem to make a servo for just about anything you could need.

@Rashad I like your DIY attitude. Good luck with the Audi purchase

Also keep in mind our heavy duty servos are pretty amazing

For the dynamixel servos, that is possible with ezb easily. The ezb is a TTL controller. In fact, it's 20 TTL controllers

Lol 20 ttl . that's good. A feature in ARC for dynamixal would be paramount! Since they have a great following for versatility and reliability. I have a few of the eZ robot high torque servos and they perform like servos you would buy for 40 to 50 dollars at your local hobby shop.

I have 18 dynamixal servos. I would love to be able to use my EZB to control them. They can be used as regular servos or turn continuous for drive servos. If the EZB could also read the servo position, that would be so cool!

Speaking of better servos... Is it possible to use two servos for one movement and have them "synced up" or would one fight the other? I am thinking of have two servos , an inside and outside for a shoulder joint. I understand one higher torque servo could do the job but having two servos is also a design/art feature for my steampunk robot/animatron FRED...
