How cool! With these new Lego NXT compatible Linear Actuators you can easily add strong linear motion to your next Lego Mindstorms project. We now offer both 50mm and 100mm varieties.

Time to expand your building power with your Lego Mindstorms®. You must be tired of rotating things all day with regular old motors. It’s time to start moving things bach and forth, up and down, in and out! Like a REAL engineer. Firgelli actuators will make you the coolest kid on the block for certain.

Lego Mindstorm®, Power Functions®, and Technic® compatible Linear Actuators. These linear actuators are self contained units which include an electric motor. They will push up to 25N and move at 12mm/s unloaded.

For use with your NXT® Brick you will need a standard NXT® connection cable to connect it in place of one of the Mindstorm® Servos, and you will need to download the Firgelli L12-NXT Block here.

For manual use with Lego Power Functions® you will require the Cable-NXT-PF available on this site. For manual use with older Lego Technic® style battery packs you will require the Cable-NXT-Technic available on this site.

It’s that time of year again! We’ve gone through the piles of various robot parts accumulated over the last year as well as products we’re moving out of our catalog to make room for new stuff, and discounted it heavily! Builders, Tinkerers, and Deal-Hunters rejoice, we’ve cut prices to move this stuff out the door quickly. Quantities are limited and if this sale is anything like last year, it will go quick, so don’t wait long. Everything from servos to beginner robot kits to wheels to chargers to batteries and much, much more! Stop by and check out all the savings for yourself in our Garage Sale section!

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:

Introducing the newest addition to the ArbotiX Robocontroller line from Vanadium Labs!

The ArbotiX Commander is an Arduino Software compatible, open-source XBEE-wireless hand-held controller built specifically for controlling ArbotiX/NUKE powered walking robots (but it can be used to control just about any Arduino powered robot). This gamepad style controller comes ready to be setup with the ArbotiX Robocontroller. The ArbotiX Commander was meant to be hacked, modified, upgraded, and otherwise tinkered with. Add additional sensors, customize it with your own handle grips, or rewrite the firmware sketch in any way you see fit!

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!

Assimilate them early! Corrupt their minds before they have a chance to live a life free from fascination with robots. Yes, we are talking about our youth. We must teach them to master the machines to avoid enslavement in the future!

Trossen Robotics has been filling the professional hobby robotics niche for half a decade now. We’ve all seen the crazy projects mentally unstable adults have been creating over there, but now it’s time to help pass the torch. The droids at Trossen Robotics are happy to announce the Grand Opening of their new sister store for the youngins, Roboticstoys.com.

To celebrate the opening of the store sure to be the favorite of baby John (and Sarah) Conners everywhere we are giving away a free robot to the first 50 orders! In reality these are spybots that we plan to put into every home as part of a secret government program, but for now you can have one free. Isn’t that exciting!?

Roboticstoys.com aims to be the number one place to find all your robotics kits, toys, and decor for that budding roboticist in your family. Robotics is a great way to spark an early interest with children in mathematics, engineering, and the sciences. There is nothing quite like building your first interactive creation and watching it come to life to kickoff a lifelong fascination of discovery and invention. Just be careful with how much time they spend behind closed doors or you just might come home to find this thing “negotiating” allowance increases with you.

As always, Thank you for being a customer and blog reader!
