Hey,

I was wondering what is the advantages of Dynamixel servos over standerd hobbiw servos like hi-tex servos. I am trying to build a bot similar to mech warfare bots but not for the actual competition. I am new to robots but have a sound understanding of mechanical systems. I am looking to get fimiliar with programming and electronics before taking on a task like competeing in mech warfare. Thanks for any advice you can give I am just trying to determine differences that support the price points. Also, I will probably be using a arduino microcontroller due to it being simple. Are the dynamixels controlled similar to regular servos or are there large differences. Thanks again!

A few pretty good answers from one of the overlords:

Strangely enough, that seems to be the same way I entered this hobby, & from the same direction too.
I have never used standard servos, but I did trawl through the lynxmotion forum for info on them, but when I started reading up on the programs they use, my eyes glazed over, & I decided to use the Dynamixels. I'm glad I did.
I also was looking at the arduino, but went with the Arbotix since the Arbotix can use the programs written for the arduino, but is actually designed specifically for robots. It has limitations, which I am only just starting to reach, & only because I am doing stupid stuff not for Mech Warfare (MW).
If you search, you will find that various people have uploaded programs for MW bots - I load Inxfergy's Pypose onto the Arbotix to get the poses I want to use, then I load Darkback2's program onto the Arbotix to run them with my own Python program from my computer. Note that since the Arbotix & Arduino are compatable, you can happily cut & paste parts of programs to make you own, once you get that far into programming.

Best of luck! :happy:

I can totally relate as well. I recently discovered this hobby through an acquaintance. I have no ambition for competition, I just just love the art :D
