Robot Dreams has been covering the Robo-One competition in Japan and just posted this video of one of our PhantomX Hexapods in a qualifying round for the 4.5 meter dash. It’s always awesome to see our crawlers traversing the globe, and soon enough there will be a PhantomX Hexapod in every city, in every country. Not that we’re planning a hexapod uprising or anything. Definitely not.

Robotis wowed the robotics community with the MX-28T, and recently they’ve expanded the MX line to include the TTL MX-64T and the MX-106T, as well as the RS-485 variants, the MX-28R, the MX-64R and the MX-106R.
These new servos have a contactless magnetic encoder, which offers 4x the resolution of the RX series. This makes them more accurate and even smoother than the old servos. Also upgraded, is the processor in each of these servos – a 32bit 72mhz Cortex M3! This beefy processor handles the newly implemented PID control algorithm. It can be used to maintain shaft position and can be adjusted individually for each servo, allowing you to control the speed and strength of the motor’s response. The new setup also offerers a 3Mbps bus. The ‘T’ variants use TTL communication and are compatible with other TTL servos like the AX-12 and the AX-18. Meanwhile the ‘R’ variants use RS-485, just like the RX series.
You might remember Don and Jason’s new robotic arm, which uses the new MX servos. But the real question is, what will you do with them?
Banter, robots, video. Go!
This video does nothing to dispel my friends’ belief that all I do is sit around and play with robots all day at work.

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!
The ArbotiX RX-Bridge expands the capabilities of the ArbotiX Robotcontroller by enabling the use of DX-117, RX-28, RX-64, and EX-106+ Dynamixel Servos. This add-on board converts your existing ArbotiX Robocontroller TTL serial ports into an RS-485 serial protocol compliant port.
The RX-Bridge answers the call for a high end, fully programmable controller for the higher end range of Dynamixels at a much lower pricepoint than other less-capable controllers on the market.
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:
We’ve been a bit quiet around here lately, mostly because we have our heads buried and are hard at work at bringing you guys some awesome new robotics products and kits! Wanted to take some time to showcase a new reworked section of our site that helps builders like you build your robots easier. Our Robot Servos & Brackets section has been completely revamped, pairing up the servos with compatible brackets and frames (tons of new varieties have been added, as well as more to come).
The Robotis Dynamixel Servos section should be of particular intrest, as we now stock individual Bioloid Frames as well as every type of DX/RX/EX Series Brackets and Frames.
Even our Hobby Servos section got a revamp, now offering Micro, Standard, and Giant Scale PWM Hobby Servos and compatible brackets!
We also started rounding up some cool user projects to demonstrate what can be done with these awesome actuators, which can be found on various related product pages. Here are a few examples!
But we’re preparing for when she shows up to blow us away, because this might very well be the start of Skynet.

Well, at least nobody can accuse us of under-engineering. Yup, that’s a pyramid of RX-64s. This is a teaser photo of a new project brewing in the Trossen Robotics Lab for the upcoming Mech Warfare competition. A fully custom aluminum frame and bracket system is being machined courtesy of Big Blue Saw, our sponsor on the project. Did we mention we’re giving it weapons? /snicker
