Newest Hardware Bounty, The Open Lidar Project

November 17, 2010 by James Munns 29 Comments

Inspired by the successful Kinect bounty put out by Adafruit, [gallamine] of the RobotBox community has posted his own ~~$200~~ $400 bounty for the first person who can hack the scanning LIDAR from Neato Robotic’s XV-11 vacuumbot. This sensor would be particularly useful to any robotic makers out there, because even the full retail price of the vacuum is less than the cost of most standalone LIDAR units, which often run upwards of $1000. The bounty seems to be growing every day, starting out at $200, and doubling thanks to a couple of other interested parties.

Luckily, from what we hear, the sensor was never made to be hack-proof (and perhaps even secretly hack friendly?), seeing as one of the prime developers of the sensor is a member of a certain Home Brew Robotics Club. We love it when companies are nice to hackers, and we hope to see more examples of this in the future. Not sure what the XV-11 is? Be sure to check out the video after the break for info about the vacuum and its scanning LIDAR.

Stupid Friggin’ Robots

November 12, 2010 by Joseph Thibodeau 4 Comments

Some robots aspire to greatness, revolutionizing our humanoid behaviour in ways we struggle to understand. They have traveled in space, photographing the stars like celestial paparazzi or snatching Martians up like interplanetary bed intruders. Some robots are happy to perform their everyday functions with dignity and grace, scrubbing our floors and thanking us for recycling.

It may seem that every robot has a calling that–whether grandiose or humble–makes it a valuable part of our society. Unfortunately, this is not the case. Some robots use our hard-earned energy resources to no good use, lazing around without a useful function, drinking flux and tonic all night while watching reruns of Lost in Space. They are stupid robots.

Many humans look upon such pitiful automatons as nothing more than flotsam in the whitewater rapids of human achievement, but the more empathetic among us are ready to celebrate the unique uselessness of stupid robots in grand style. Enter Bacarobo (translated), the premier event showcasing the quirkiest and most amusingly useless robots of our time.

This year the contest was held at the end of October, and the entrants were hilarious to say the least. The dancing olé-bot drew much applause, while the shivering toque robots wooed the crowd in a desperate attempt to escape their frigid prison. It will be fun to see whether any stupidly adorable robot designs will come out of our own Santa-bot competition, considering the source material. If you’ve ever built a stupid or useless robot (accidentally or not) please share your story in the comments. Sometimes the most endearing things about our technology are the parts that don’t work the way they’re supposed to.

Japanese Micro Planes

November 11, 2010 by Chris Nelson 27 Comments

Some very well engineered micro planes(translated) have been buzzing around the net. The goal here is ultra light weight. These suped-up paper planes have a remarkable target weight of around 10 grams (translated). The lighter the micro plane is the slower and more maneuverable it will be leading to some pretty interesting and scary applications. For controls it looks like many of the planes are using infrared receivers/transmitters (much like you would find in a TV remote hint hint). Getting the lightest plane possible has forced the designers to come up with some pretty ingenious tricks. For example, instead of using packaged servos they use a coil of wire wrapped around a rare earth magnet to control the flaps. You can see these home made “servos” in action after the break.

Some have taken a more classic approach and used rubber band power instead of a li-po/motor combo.

Single-motor Walker For Santa-Pede Challenge Inspiration

November 10, 2010 by Mike Szczys 11 Comments

This LEGO hexapod uses just one motor for motion. In the video after the break you can see that what [Valetnin Bauer] accomplished is almost magical, using just 210 parts. A central drive shaft uses worm gears to transfer motion to each of the legs. The limb mounting technique results in a sort of rowing motion that closely mimics what you’d expect to see from a biological hexapod.

We thought this might provide some inspiration for the Buy Break Build: Santa-pede challenge. Sure, using LEGO is a lot easier than reusing Santa parts. But a lot can be accomplished with a little creativity. Another point of inspiration might be this one-motor walker that should be a snap to adapt to the challenge. Better get going, just twenty days let until the project deadline!

Robotic Mobility For The Little Ones

November 10, 2010 by Mike Szczys 20 Comments

Researchers at the University of Delaware are helping disabled kids by designing robot transportation for them. Exploring one’s environment is an important part of early development. Disabilities that limit mobility can prevent young children from experiencing this. Typically children are not offered a powered wheelchair until they are five or six years old, but adding intelligent technologies, like those found in the UD1, makes this possible at a much younger age. Proximity sensors all around the drive unit of the robot add obstacle avoidance and ensure safety when used around other children. When confronted with an obstacle the UD1 will stop, or navigate around it. The unit is controlled by a joystick in front of the rider but it can also be overridden remotely by a teacher, parent, or caregiver.

ROS Turns Three

November 9, 2010 by Chris Nelson 4 Comments

Turtles!

Since its first debut three years ago, ROS has been gaining some popularity with the robotics folks. It’s behind the scenes of those impressive quadcopters you may remember from a while back. ROS helps abstract the lower level functions of a robot by supplying lots of code for commonly used components (wiimote for example). Being an “operating system” it comes with lots of nice features you would expect, like a package manager. It’s open source and many of their projects are well documented making it easy get started.

Check out the video after the break to see it in action Continue reading “ROS Turns Three” →

DIY Coffee Gripper

November 4, 2010 by James Munns 20 Comments

Here at Hackaday, we love it when people make home brew versions of elaborate, expensive, and technical equipment. By gathering up some coffee grounds, a balloon, some plastic tubing, and his lungs, [Carlos] has provided a good how-to on making your own coffee grounds robotic hand. Inspired by the U. Chicago, Cornell, and iRobot Collaboration we previously covered, he is one robot and a vacuum pump away from having their setup. Check out his blog for a list of components as well as a couple hints to help the build go smoothly. Be sure to check out the video after the break.
