Another chapter for BrainBot

So, the grippers mentioned in my post yesterday are for a new BrainBot* robot. Well, not exactly a new BrainBot, but one with a significantly different movement protocol. We saw the new Johnny-5 robot at Lynxmotion, and decided that would be an ideal base for BrainBot, so they can concentrate on vision and manipulation without having to worry about locomotion.

Of course, walking is still important, so the robot will have an interchangeable base plate that can transform it from a tracked base robot to a walking robot. The motor control for the tracked base will come from my general I/O module, so the entire tracked base will become just another bus device.

In case you're wondering what the funny face pictures around the camera are, they are to allow BrainBot to express emotions. Of course, each LCD panel will be just another bus device on the Bioloid bus.

Catching up Again

Wow, time really flies... I spent a big chunk of July catching, and recovering from pneumonia. I opened my web store for Bioloid accessories - http://www.huvrobotics.com. People are buying IMUs and USB bus interface boards. I'm still waiting on a new stencil for my foot pressure sensor board, so I can start making them again without wasting 2 boards out of 3.

Oh yeah, and I got the first prototype new gripper working. This new gripper is designed to use a couple AX-12's as the actuators, just to make things simple.

Here's a movie of it working: Gripper-Working (5.9 MB)

The Brain Engineering guys are going to use these grippers on a new version of BrainBot that I'm working on.
