SMALdog, Sorta Maybe Almost Littledog

Friday, December 11th, 2009

If this robot looks vaguely familiar, it’s because it is inspired by Boston Dynamic’s LittleDog.

SMALdog, or Sorta Maybe Almost LittleDog, is Mike Ferguson’s (creator of the Arbotix Robocontroller) latest addition to his AX-12+ based quadrapod robot lineup.

littlerdog

Rather than utilizing the more common ‘lizard-style’ leg configuration, SMALdog has a more ‘mammal-style’ leg configuration that provides some interesting walking gait variations. The biggest difference is even with very little gait programming done so far, it’s already faster than the award winning Issydunnyet quadrapod. There is still a lot of work to be done on refining the walking gait, and the turning gait is barely functional, but this platform certainly shows promise. Check out Mike’s thread for more information and updates!

Just in time for Halloween!

Tuesday, October 27th, 2009

Forum member WGhost9 has the right idea; build a robotic spider to pass out candy at Halloween. Creeper2 looks like a cousin of the Phoenix Hexapod, but a bit bigger and with more powerful HS-5645MG servos! Definitely a cool way to scare some kids for Halloween. /devilishgrin

Matt Trossen, Hagetaka, and Roboard Featured in Make Magazine

Monday, September 21st, 2009

This month’s Make Magazine (Issue 19) is the yearly Robotics Hobbyist special, and features my boss Matt Trossen once again stealing all of my glory and talking about his take on the current state of hobby robotics. That is okay however, and I’m prepared to take it with stride because anyone reading this blog knows I’m the true brains behind this operation. Not only that, but I’m also better looking (it’s the beard) and I embrace an air of dignity and modesty.

Speaking of my dashing good looks and superior mental prowess; Make also featured my currently shelved and ego-crippling project Hagetaka. Rest assured; my wife and 2 year old have picked up 2nd jobs to fund this project further and it will return with even stronger servos and bigger guns, ready to assist me in my plan for world domin- err, winning Mech Warfare.

Last but not least, Make Magazine readers got a quick and to the point review of the Roboard, the first full featured Robotics Computer on the market.

But seriously, be sure to pick up a copy as the entire issue is full of fun projects and robotic tidbits sure to appeal to your average robot-geek. And like Christmas, it only comes once a year!

Take the XMOS challenge!

Monday, June 29th, 2009

Who doesn’t like free stuff? XMOS is offering some development kits of their new event driven parallel processors to qualified parties and individuals. These controllers looks like they pack a punch in terms of features and processing power and would make an awesome robotics controller! If you’re interested, check out the forum post by XMOS and answer the requested questions. Definitely shows some promise, check out the forums and the videos below for more info.

XMOS event driven processors allow you to execute code in parallel which could open up a number of possibilities to evolve your robots “mind” to the next level!

I have some development kits to give away potentially, but before I give away all the details, I just wanted to see if there was any interest.

People have made some cool stuff with our tech before (See videos).

Some details of the processor itself which will be on the dev kit (to be released soon):

- Single core device (Although we do have quad core versions – ask me)
400 MIPS per core.
8 Threads per core.
64Kb RAM
8KBytes OTP memory for applications, boot code or security keys, with security mode
64 user I/O pins
- Support for high performance DSP (32 x 32 → 64bit MAC) and cryptographic functions
- Time aware ports provide up to 10ns timing resolution
- Designs implemented using a software-based design flow (can program in C or XC – very similar to C but with support for extras such as parallel execution)
Scalable – can connect many kits together for crazy amounts of processing power using Xlinks.

A-Pod will make your jaw drop

Sunday, April 5th, 2009

We posted a few weeks ago about TRC member Zenta’s new creation, the A-Pod Hexapod. Zenta, who created the infamous Phoenix Hexapod, is seriously one of the most talented roboticists we have seen and we’re glad to call him a much valued member of our Community!

He has made some serious progress with his latest A-Pod, and rather than gab away at how awesome it is, check out the video and prepare to be amazed.

RX-64s are crazy strong…

Monday, February 23rd, 2009

Our good friend Jon Hylands (who is an amazing Roboticist, definitely check out his work on the Bioloid system) is working on a few new projects and shot a quick video which is pretty impressive to anyone who has ever built a robotics arm. What you see in the video below is an RX-64 Robotis servo lifting a full coke can at a 30 cm arm length. While that seems trivial to we humans, packing that much torque into such a tiny servo is a great demonstration of how much servo technology has advanced in the last few years. The servo isn’t even being strained during these tests. You might note a bit of jerky movement, that is because the servo is being manually fed positional instructions via a slider bar. Most advanced robots use some form of interpolation which smooths movements considerably.

We’ll also be revealing our big internal project which uses 14 of the RX-64 servos in the near future… =)

February ‘09 Contest Winners Announced!

Monday, February 2nd, 2009

The time of reckoning is nigh! The contest winners for this round of the TRC Project Contest have been decided and we’ve got some awesome prizes to give away!

- – - – - – - – - – - – - – - – - – - – - – -

Runners-Up:

Plinter Roving Servobot

Project: Roving Servo Bot
Creator: Pinter75
Prize: $25 Gift Card to the Trossen Robotics Store

This bot went back to the basics. Base board? Check. Super Glue? Check. Zip ties? Check. Ingenious scratch built onboard controller? Check! Throw all of these items together and you have a great wheeled platform with a fully functioning arm. complete with a .NET interface over Bluetooth. The craftsmanship on this bot is superb, so much so that when we first saw it we thought it had been cut from a 3D printer. Pinter75 has taken the project a step further and will be offering it in kit form in the near future, something we are very excited to see come to life.

Charlie

Project: Charlie
Creator: Darkback2
Prize: $25 Gift Card to the Trossen Robotics Store

Quadrapods have been around long enough that it usually takes something really special to perk our eyebrows, which is exactly what Charlie the Quadrapod did. Was it the onboard PC that impressed us? The rugged raw metal look? Perhaps the fact that Charlie wields a fully automatic airsoft gun on its back? While all of that is very cool, what amazed us most of all was the fact that Charlie was built by hand, using only simple power tools. No CNC machine, no computer CAD drawings; the brackets and frame were literally cut and bent by guide of hand alone. Anybody who has built parts by hand knows how much patience and skill goes into making identical parts without the guidance of a computer controlled blade. Look for this bot competing in the upcoming Mech Warfare competition at Robogames 2009!

Lego WALL-E by Bizmarc

Project: Autonomous LEGO Wall-E
Creator: Bazmarc
Prize: $25 Gift Card to the Trossen Robotics Store

Building a Wall-E robot? Awesome. Building it out of LEGOs? Even more awesome! LEGOs sure have come a long way in their lifetime, evolving into the amazing robotics prototyping tool they are today and invoking nostalgia in tinkerers abroad (I mean, who didn’t play with Legos growing up?) Forum member Bazmarc blew us all away when he debuted his LEGO NXT Autonomous Wall-E project, sparking “LEGO-skill” envy unanimously across the forums. Not only did he perfectly capture the look and feel of everyone’s favorite trash bot, he brought it to life with an autonomous navigation system. We can’t to see what Bizmarc comes up with next!

Third Place:

animatronic Head from Willettfx

Project: My Animatronic Project

Creator: Willetfx
Prize: WowWee Roboquad™

What happens when a professional dental tech with a knack for animatronics is mentored by Hollywood special effects legend Dick Smith? A very creepy and very realistic animatronic robot is born. Gary Willett (aka Willettfx) has a true passion for his work, spending hundreds of hours adding the finest details to truly bring his monstrous inventions to life. He shared with us hours of video showing the fine artwork and dedication that goes into building Hollywood quality animatronics, and we ate up every minute! If you’re looking to get into animatronics yourself, he also offers a 3 disc DVD set showcasing every step on how he built his outstanding project!

Second Place:

Robotic Marionette by Sunithaya

Project: Robotic Marionette
Creator: Sunithaya
Prize: WowWee RS-Media

The Robotic Marionette project literally reads out like a story. Forum member “Sunithaya” joined us after he had already completed his Marionette project of two years, however he started from the beginning in chronicling the lengthy steps made during the design, building, and final performances. Each post is titled appropriately – as if a chapter in a book, and detailed thoroughly with the thought process that went into each artistic design decision. Tons of photos were taken throughout the life of the project, and it all pays off with a performance video of the Robotic Marionette autonomously dancing. This project thread is a true gem that we’re lucky to have on our forums. We highly recommend a complete read-through to everyone interested in learning more.

First Place:

k9 by DJsures

Project:K-9 Autonomous Robot Pet
Creator: DJSures
Prize: Pleo™ from UGOBE

DJSures pulled down some serious ‘geek cred’ by creating his own K-9 robotic dog. I mean, what self respecting geek doesn’t want their own robotic pet to do their evil bidding? Sure it doesn’t have “omniflexible hyperlink facilities” or the ability to teleport, but this loveable Dr. Who tribute still boasts some impressive features. Onboard 3D mapping capabilities, real time occupancy grids, speech synthesis, adaptable personality levels depending upon the amount of human interaction, obstacle avoidance, an LCD screen for diagnostics, and even the ability to follow people around! Now get this: the entire robot was scratch built. This project is a perfect example of how it doesn’t take four dozen servos, onboard PCs, or complex vision processing to win our contests. Ingenuity, creativity, and the overall presentation of your project are a huge factor in our judging decisions. Watching this little bot go from pieces of plastic and circuitry to a seemingly free willed artificial being is what won DJSures the first place prize in the latest round of our contest!

The Trossen Robotics crew would like to personally thank everyone who has participated in our contests as well as those who have helped other projects along. What started out as a great way to encourage grassroots engineering and the sharing of knowledge has evolved into a community of hobbyists and professionals who exhibit a passion for their work unlike any we have ever seen. Innovation is viral, and watching builders literally feed off of the excitement fueling these projects is a great thing to experience on a daily basis. We invite anyone looking to get started in robotics, as well as the veterans who have many of bots under their belt, to join the Trossen Robotics Community. We encourage you to jump in head first, if you’ve got an idea- discuss it, if you have a question- ask it, and if you’ve got a project- enter it in our contest. We look forward to seeing you and your projects in the next round of the Trossen Robotics Community Project Contest!.

Pololu Custom Laser Cutting Service Rocks!

Friday, October 3rd, 2008

Creating custom parts for your bot can be a daunting task. That is, if you don’t know about Pololu’s Custom Laser Cutting Service. I recently needed some custom parts created for the upper torso of one of my bots for Mech Wars, and after look around a bit I decided to try out their service.

I have to give my highest recommendation to this service provided by the great folks at Pololu. I personally can’t afford a CNC or Laser Cutting machine, but now I don’t need to. I sent in a 2D CAD file of my design (they can also create one for you from a drawing), selected what type of plastic I wanted it cut from, and they got back to me promptly with a price quote which made my jaw drop. Extremely affordable, prompt and courteous service, and the results were fantastic. Again, I can’t recommend their service enough, it should literally be considered another tool in your toolbox. If needing a custom part for your project ever held you back, look no further.

Here are some pictures of the parts I ordered (Click to Enlarge):

Here’s the assembled upper torso with Airsoft guns mounted.

And here’s the frame of the Mech, Hagetaka, put together (for the most part, needs a lot of work and a paintjob):

Phoenix Hexapod continues to similtaneously impress and creep us out

Tuesday, September 23rd, 2008

Zenta from our Community Forums continues to blow us away with his scary good trig skills, specifically when applied to Inverse Kinematics in his Phoenix Hexapod. This time he is showcasing a dynamic balancing scheme throughout a variety of different walking gaits… and if that wasn’t enough, wait until he pulls the walker up with one leg and starts shifting the body around. The fluid, lifelike movement of this Hexapod is truly amazing, check out the video below to see what we’re talking about.

We love Tramps!

Wednesday, September 10th, 2008

And no, not the kind you shy away from bringing home to Mom. Specifically, we love T.R.A.M.P. (Trossen Robotics Autonomous Mapping Platform).

The members of the Trossen Robotics Community are at it once again, this time collaborating on a robotics project best described as “a Mars Rover, but for Earth”. This is quite an aggressive project, only made possible by the fact that the development team consists of a range of specialists working together.

The basis behind the project is to create a robot that will be shipped to various members of the Community to explore and log different areas around their house and outdoors. Once it has arrived and is set loose in its new environment it will scan the surroundings using an array of sensors and upload the results to the official Tramp website. Features include:

  • The ability to track and log its travel around the world via GPS, displayed via Google Maps.
  • Scan its surroundings using cameras, range sensors, and LIDAR.
  • Use sensory data to create a 2D and 3D render of the area around it.
  • Sample and log the environmental air quality.
  • An onboard PC for the main controller.
  • Pictures, video, and statistics will be uploaded to the site.

Here is a video of the initial base prototype. At this point in design it looks sort of looks like a trashcan with wheels (the project members are totally going to kick me), but we’ll keep you up to date with progress reports as the project matures. At the end of the video you get a sneak peak under the hood.
