I won’t even pretend that I understand all that is going on in the walking gait here, but this is darn near human-like in every aspect. And being able to walk like that is one thing, being able to recover from a sideways push is an entirely different accomplishment all together. Absolutely brilliant.
Looks like iRobot is determined to bring Judgment Day upon us. First with the military bots, and now they’re trying to build a liquid-metal-shape-shifting robot that will surely ask us if we are John or Sarah Connor. Okay, not quite, but it looks like they’re headed in that direction.
This week at IROS 09 (Intelligent Robots and Systems), iRobot and the University of Chicago unveiled a soft, blobby robot that looks something like an inflating marshmallow.
The new robot, called chembot, changes the shape of its stretchy polymer skin using a technique called “jamming skin enabled locomotion”. This means that different sections of the robot inflate or deflate separately; controlling this inflation and deflation enables the robot to move. DARPA, which is funding the project, hopes to use the robot to squeeze into small holes or under doors, which I’m guessing would be used for sophisticated surveillance.
We’re officially launching this much anticipated new Robocontroller today! Thanks to all of those who pre-ordered, your board should be on it’s way! Our initial stock of these is limited, so get em while they’re hot!
The arbotiX Robocontroller, an advanced 3rd party Bioloid controller, is now in stock and ready to be sold! It incorporates a powerful AVR microcontroller, XBEE wireless radio, dual motor drivers, and 3-pin servo-style headers for IO.
The arbotiX robocontroller is specifically designed to control robots built using the Bioloid System and AX-12+ servos, although it is also a very high-end solution for powerful rovers. It is not intended to be a drop-in replacement for a CM-5, rather it is intended as a high level development tool for building more sophisticated robots.
We’re officially launching this much anticipated new Robocontroller tomorrow, but we figured we would give our faithful blog readers a chance at one before we do a main page announcement.
The arbotiX Robocontroller, an advanced 3rd party Bioloid controller, is now in stock and ready to be sold! We still have some additional information to add to the page, as well as a new ISP programmer we picked up… but for those of you wanting to get the ball rolling, check it out and pick one up while supplies last! Our initial stock of these is limited, so get em while they’re hot!
Phidgets have long been a favorite for computer software developers due to their ease of use, wide selection of sensors and I/O boards, and solid API offering for a variety of programming languages. The one thing that has always been a requirement however, is a physical connection to a computer via USB cable.
All of that is a thing of the past now with the introduction of the PhidgetSBC; an Arm9 based embedded Linux computer (it runs a custom Linux Distro built using Buildroot) combined with the tried and true Phidgets 8/8/8 IO Board.
So what does that mean to you? In its simplest form and function, it effectively cuts the cable of your Phidgets projects and allows you to access your Phidgets devices over ethernet or the included Wifi dongle. The onboard computer acts as a server for the variety of APIs that Phidgets offers, and this enhanced ‘mobility’ opens the doors to a much wider variety of applications. The PhidgetSBC can function as a wireless extension of your PC, a Wifi enabled Robot Controller, or even a standalone Robot Controller. That’s right, the PhidgetSBC is fully programmable; there is an easy to use interface that allows you to load custom C or Java code directly to the board and have it run autonomously, without the previously required PC link. If that wasn’t enough, more advanced users can modify the Linux build to their hearts content, host other USB based Phidgets devices by simply plugging them into the PhidgetSBC, and has integrated support for streaming a web cam feed back to your PC. I’m really just skimming the surface here, for more details check out the (as always) very well documented product manual.
The PhidgetSBC will run you $243.90 USD and we are currently accepting pre-orders for this as we anticipate it to be a very high demand product. Given that the development kits for the onboard computer used here usually run in the ~$150-200 range, this price is a VERY good deal to anyone looking to take their Phidgets projects to the next level. Initial quantities will be limited and orders are filled on a first come first serve basis, so get your pre-order in ASAP to snag one up!
The complexity shown in LittleDog’s adaptive gait and terrain navigation seriously makes my head hurt. If you consider yourself a geek you are of course familiar with BigDog; the 4 legged robot that robot dreams are made of. LittleDog is similar in concept but at a much smaller scale, and MIT has been using it as a research platform for a number of years. Evan Eckerman from Botjunkie sums it up quite well:
Researchers at places like MIT have been usingBoston Dynamics‘ LittleDog robot for years now as a testbed to teach legged robots to learn how to traverse variable terrain on their own. This video shows some highlights of a “dynamic double-support gait,” which means (as near as I can tell) that LittleDog is supporting itself, at times, on only two of its four legs. This is a substantially more efficient way of negotiating terrain thanwe first saw two years ago. LittleDog also demonstrates some markedly biological ways of negotiating obstacles (with the possible exception of the belly flop on the Jersey barrier)… I especially liked how it pranced in place slightly before tackling each stair. All this stuff is obviously a lot of work for a little bot, since poor LittleDog completely collapses at the end of every test.
LittleDog, remember, is teachingitselfthe most efficient way to negotiate these surfaces. Overhead cameras examine the terrain and plan out LittleDog’s route by computing a ‘cost’ for each step, which takes into account the distance moved towards the goal as well as the potential for a fall. After a lot of trial and error, LittleDog figures out how to best compromise between progress and stability, and the lessons it learns could be propagated up toother, larger quadruped robots.
This video is from Phase 2 ofDARPA’s Learning Locomotion program… MIT’s LittleDog team was awarded funding for Phase 3 of this program back in 2008, so we’ll keep you updated.
We’re good friends with the folks over at Vanadium Labs; some very talented people who have been in the robotics game for quite awhile but have just now established their official company. This is great news for the robotics community however, as they have some pretty amazing products on the horizon. One product in particular is the new arbotiX Robocontroller, an advanced Open Source microcontroller tailored for the Bioloid system and AX-12+ servos.
The arbotiX robocontroller is an advanced control solution for small-to-medium size robots. It incorporates a powerful AVR microcontroller, XBEE wireless radio, dual motor drivers, and 3-pin servo-style headers for IO.
The arbotiX robocontroller is specifically designed to control robots built using Bioloid servos, although it is also a very high-end solution for powerful rovers. It is not intended to be a drop-in replacement for a CM-5, rather it is intended as a high level development tool for building more sophisticated robots.
So what we have here is an Arduino IDE compatible microcontroller with a plethora of I/O, plug and play capable with AX-12 servos, and an Xbee Wireless Link to your PC. It’s also worth mentioning that this was the controller used in the robot that won Year 1 of Mech Warfare, Issydunyet. For more information on the controller check out the Vanadium Labs website.
Trossen Robotics will be exclusively distributing this exciting and powerful new Robocontroller with an estimated release date of Mid-October 2009. We’ll have more details in the near future, stay tuned!
Want to see the arbotiX in action? Here is a quick video showing a basic Inverse Kinematics demonstration on Issydunyet!
We came, we conquered. Mech Warfare’s first year at Robogames 2009 was a success. We had a professional video crew on hand to record the action from multiple synchronous security cameras mounted within the arena, and even threw our interns inside during a few matches. This video is a highlights compilation of some of the robots that competed, enjoy!
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.
Remember when we teased you with a stack of RX-64 servos? Well its time to unveil a bit more of what we’re working on for the upcoming Mech Warfare competition at Robogames 2009. Meet Hagetaka; a 7DOF per leg biped built around the powerful RX-64 servo from Robotis. This robot boasts 14 RX-64s, 2 RX-28s, a custom aluminum chassis machined by sponsor Big Blue Saw, an onboard linux based Gumstix computer with a PS3 Sixaxis controller , a WiFi video server using a Headplay Personal Cinema System for remote piloting, and of course dual automatic airsoft guns. Video and more info will be available in the near future, and be sure to check out the June issue of SERVO magazine for the first in a series of articles detailing the build process of this Mech.
