Building a robot arm – Days 1 and 2

I’m attending a second course based on Arduino development. The objective is to build a prototype in five days. This time I’ve partnered up with Mark Laatikainen and together we’re building a controllable robot arm.

An early sketch – Professional, as always

We decided to use Tower Pro micro servos and potentiometers to control the servos. At first, joysticks seemed like the best choice, but we switched to potentiometers because of their simplicity.

Here are some pictures of the early build and a quick video:


Stay tuned for the finished prototype. In the meanwhile, you can check out the course taught by Tero Karvinen over here:
