Just in time for Halloween!

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

Boston Dynamics does it again

Whoa. Just Whoa.

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.

Giger is ready for iHobby!

Andrew — Wed, 21 Oct 2009 21:08:31 +0000

We’ve been busily preparing for the iHobby 2009 show this week, but I figured I would share a little demo video of Giger. He now sports a TinyCylon eye from DaleWheat.com, and has a few new fighting moves up his sleeve, ready for some fights at Chibotica during iHobby! Walking gait is still obviously a work in progress, but what is being demonstrated in the video is the ability to pan/tilt the torso while walking, which makes the walking gait even more unsteady. Enough jabbering, here’s a bit of video!

One Step Closer to T-1000!

Andrew — Thu, 15 Oct 2009 16:07:10 +0000

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.

Serializer WL Robotics Controller now under $100

Andrew — Fri, 09 Oct 2009 18:34:32 +0000

.NET Developers rejoice! The Serializer WL has dropped $30 in price down to $99.95, making this powerful robot controller even more accessible.

Easy Robot Control using .NET or Robotics Studio:

The Serializer WL Robot Controller provides a ready-to-use solution to interface the Microsoft™ .NET framework or Microsoft™ Robotics Studio to common robotic hardware.

Never before has it been this easy to interface DC motors, servos, analog sensors, I2C devices, single and quadrature encoders, switches/relays, and other devices to the .NET framework and/or Robotics Studio.

Be sure to check out our Xbee section for add-ons for this awesome controller!

arbotiX Robocontroller Now Available!

Andrew — Wed, 07 Oct 2009 00:26:30 +0000

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.

For full information and product manual, check the manufacturer’s page.

arbotiX Robocontroller Specifications

16MHz AVR microcontroller (ATMEGA644p).
2 serial ports, 1 dedicated to Bioloid servo controller, the other to the XBEE radio
3 Bioloid AX-12+ style ports onboard, plug your AX-12+ Servos directly in!
32 I/O, 8 of which can function as analog inputs
Servo style 3-pin headers (gnd, vcc, signal) on all 8 analog inputs, and 8 of the digital IO

We have also put together the arbotiX Robocontroller Starter Kit that includes everything you need to get started, including a pair of Xbee radios, an Xbee USB Explorer, and a USB AVR Programmer!
