Markus shared his Omnidirectional remote controlled robot:

Recently, I got interested in omni wheels, so I built this little robot. The robot has three pairs of omni wheels. I covered each roll of the omni wheels with liquid rubber (plastidip) to get better traction. I bought the cheapest servos I could find and modified them for continuous rotation. The robot is powered by four eneloop NiMH batteries and controlled by an Arduino nano 3.0.

A self balancing two-wheel robot that wobbles, hence the name WobblyBot. Quite possibly the simplest design for a robot that could (sort of) balance itself on two wheels, without the use of accelerometer, gyroscope or microcontroller. A great weekend project, and do check out the ...

iRobot on its way to Japan. 

IEEE said on Friday that iRobot is sending four of its robots to aid the workers at the Fukushima Daiichi power plants.

The robots being sent include the Packbot 510 and the Warrior 710. Both bots have wireless video, remote control and sensors/detectors. The Warrior 710 can navigate rubble, climb stairs, and even deploy the smaller Packbot.

This will give the brave workers another tool to look at what is going on inside the power plants.

Autonomous quadrotor makes internal 3D map of multi-level building

3d map

Do you remember the MAVs, those little autonomous tiny bugs that will change (in the future) the warfare? Here is something bigger and less harmful, but it is a proof that autonomous flight in buildings is more realistic than ever. Youtube user frankerssj uploaded a video demonstrating an autonomous quadrotor, that flights inside a building with multiple floors, stairs and narrow corridors. The quadrotor is equipped with an IMU, camera, and laser scanner with deflective mirrors, and generates in real time a sparse 3D representation of the area. All computations are performed onboard using a 1.6GHz atom processor. This bot is able to fly with success in environments where no GPS access is possible. An RRT based planner provides an anytime planning solution that fits the computational constraints of the robot. This planner also enables online re-planning and obstacle avoidance. An LQR optimal controller with external force compensation enables reliable autonomous flight in highly constrained environments, such as hallways, doors, and windows. The robot is able to track the high-level plans accurately. Visit frankerssj's channel for more.

3D Exploitables

My Blank Pony by MaskedRetreiver

An exploitable is an image (or series of images) with large empty areas or speech balloons that are intended to be filled with humorous text.

Just in time for Pattywac’s mashup challenge, Alan Ecker has uploaded a Pony Template Blank.  This may just be the very first thing uploaded to Thingiverse that was uploaded is a “blank slate” made available with the explicit intention of being hacked, mashed, and derived into something else entirely.  I love this idea and really hope we see more of them.

There’s been a bit of mash-up madness on Thingiverse lately.  The creations range from really useful to downright scary.  What’s especially amusing is how some of these things pop into existence.  I’ll call this the Ghostbusters phenomena.  If you think of the Stay Puft Marshmallow man, he’ll magically appear.

“Gosh, I hope no one makes an octopus”  POOF!  There’s an octopus uploaded to Thingiverse!
