Cross Dressing Robots!

Thursday, August 18th, 2011

Our old friend Che is a bit special. He has pet ducks, snakes, really ugly dogs, and a really hot wife. He wears his mom’s leather pants. He’s also into robo-masochism: meaning he lets his paintball-equipped robots shoot the crap out of him, all the while filming it for the internet’s enjoyment. We have weird friends.

He also has a great custom humanoid project that he has shared with the TRC, Hi No Hikari. This rather large humanoid robot is a kung-fu competitor and Mech-Warfare veteran. “It” also wears dresses, kimonos, and sometimes has flowers tucked into it’s mechanics. I don’t know, don’t ask me. We’re fully supportive of alternative robot lifestyles, but sometimes it’s better that we just not ask. Giger did not appreciate the dress at last year’s Mech-Warfare. He muttered something about “damn hippies” and proceeded to shoot Hi No Hikari in his/her flowery face.

With all that said, it’s been a great learning experience for Che, and one that he has shared with us every step of the way. This was his first attempt at a PLM design and he started off using AX-12+’s, eventually upgrading to the more powerful RX-28s.

Seeing this project progress from Hi No Hikari’s first steps to what he’s achieved now has been great! Check out his latest progress in the video below, we can’t wait to see even more come from this project!

Giger v2.0 – Initial Walking Gait Progress

Tuesday, March 2nd, 2010

New upgrades! Giger now uses 10x EX-106+, 6x RX-64s, and 8x RX-28s for a total of 24 DOF.


Giger’s upgrades got finalized late Sunday night and I had a bit of time to sit down and start to work on the walking gaits (from scratch). The EX-106+ is roughly 4x more precise than all previous Dynamixels, so the positional values do not translate over well when upgrading from a previous model. What does that mean? It was far simpler to just start over rather than try to scale the values step by step. All new custom brackets used in the legs and feet, as well as new elbow/shoulder brackets and arm extensions. Brackets were designed in Autodesk Inventor 2008 and machined by Rapid Sheet Metal. It’s worth mentioning that all of the custom, as well as the stock, brackets and frames that are used in Giger’s arms and legs are available in our store on our Dynamixel Servo & Bracket page! Even his ankles/hip joints or his entire legs!

A lot of projects tend to only show updates after many dozens and/or hundreds of hours of progress, but I like to show the little steps as I feel it gives one a better view of the evolution of a project and what goes into making a robot work. Keep in mind; I have this gait tuned to a very slow rate so that I can work on the balance and COG shifting correctly, it can then be sped up to a more realistic, useful speed. Here’s a short video of my initial walking gait progress (about 2 hours of programming work so far) on Giger 2.0:

New parts are in the house!

We have more goodies in and cannot wait to share! We’re serious, it’s like Christmas morning each day we get new stuff in, just ask our extremely annoyed shipping/receiving department about it. New product shows up and our techs swarm in like vultures!
First up we have the Propeller Education Kit which is an absolute steal at $99.99. Included is everything you need to get started using Parallax’s very capable Propeller microcontroller technology. Why use a normal microcontroller when you can get 8 of them in a single chip? Included in the kit is a Propstick USB, a Propeller Fundamentals Lab/Project book, various components needed for said projects, and some neat interconnecting breadboards for rapid prototyping.

We’re also proud to introduce our new Mosquit-IO Pan/Tilt kit! The Mosquit-IO is a board we had custom designed specifically to answer the call of a low cost pan/tilt controller, bringing the price down $20 from our previous Pan/Tilt Kit. The Mosquit-IO can control two servos and a 6v DC motor, and is also available separately. A USB interface, simple command syntax, and provided .NET example code make this very easy to get up and running.

Drooling over the insane torque and features of the DX-117, RX-28, RX-64 Robot servos from Robotis? We are too, and we’re making it even easier to implement them into your next project by offering a High Quality Aluminum bracket system for these. Hinge brackets, side brackets, bearing hubs, and thrust bearings! Everything you need to get started in building the ultimate high torque robot!
