Servos for Dinky

Until now, I’ve only had some experience with simple hobby servos (the cheaper the better, I thought, never bothering with much research or trying to pick specific types/brands or looking at parameters like torque – just tried to use whatever I could get, hoping for the best). Hobby servos are of course well understood and work reasonably well for robots, but their control method is a bit crude (no position feedback) and not very accurate.

When looking around for various robot arm projects for inspiration, I frequently came across the Dynamixel servos from Robotis and was intrigued, wanting to try something “serious” this time.

At least two-three years before learning about PiWars I was thinking of making a walking robot. As with many things I couldn't start small: I thought the easiest way would be to make a 6 or 8 legged one: Raspberry Pi powered, 3d printed body, servo drive legs and servos in all the joints. And to make it 'properly' - each leg to have three degrees of freedom. That meant 8x3 servos + a couple spares, so I ordered 28 servos in total.
