"In a previous post, I talked about building custom lego parts. Today, I am going to talk about something a little more advanced. Today, I am going to talk about the GumBrix.
"The gumbrix came about because so many of my robot projects required the kind of rapid prototyping that Lego really excels at, yet required more in the way of control electronics than Lego was capable of. With a maximum of 3 motors and 3 sensors, the Mindstorms kit was not really capable of the more complicated control strategies that I was interested in. For example, it is possible to build a balancer, but not one with a touch sensor and proximeter as well, and certainly not one with arms. At the same time, custom machining every single part for a balancer is VERY time consuming, and not flexible once assembled..."
