Foam Board Servo Driven Arm

[Lucky Larry] posted some pictures to the Hack a Day flickr pool that caught our eye. He made a quick and cheap servo driven arm. Constructed from foam board and some hobby servos, he’s using an Arduino for the brains. You can download the pattern for the arm pieces as well as the code on his site.

He ultimately finds that he has positioning issues that he blames on the cheap servos. You can see in the video on his site that the circles it is drawing are drifting one direction.

Toddler Android

We came across a couple of videos of this toddler android. It sits up, rolls over, and responds to humans around it using visual, audio, and sensor inputs. After the break you will see that the movements are quite like that of a young child. The giveaway is the weight of the robot which is evident when its handlers trying to help it get untangled from that blanket. It seems to respond to individuals around with a smile and a twinkle of its… errr… camera eye. We wonder if it would find delight in knocking down some dominoes.

Distributed Flight Array

Though it is in the beginning stages of development, the Distributed Flight Array is already looking very interesting. Each unit can scuttle across the ground using the down force from its prop, but when 4 or more join forces, they can take off and fly. The documentation shows that they should be smart enough to fly in random configurations, though in the video we only see the standard 4 prop layout. This is being worked on by the same people who produced the balancing cube.

Intelligent Ground Vehicle Competition 2010 Day Two Report

Culture Shock II, a robot by the Lawrence Tech team, first caught our eye due to its unique drive train. Upon further investigation we found a very well built robot with a ton of unique features.

The first thing we noticed about CultureShockII are the giant 36″ wheels. The wheel assemblies are actually unicycles modified to be driven by the geared motors on the bottom. The reason such large wheels were chosen was to keep the center of gravity well below the axle, providing a very self stabilizing robot. The robot also has two casters with a suspension system to act as dampers and stabilizers in the case of shocks and inclines. Pictured Below.

Intelligent Ground Vehicle Competition 2010 Day One Report

The Intelligent Ground Vehicle Competition (IGVC) is the precursor to the DARPA Grand Challenge, and in many ways it is just as difficult. We have the pleasure of being at the competition this year with the Tennessee Technological University Autonomous Robotics Team. The teams at the competition pull off some amazing home-brew robotics, so we’ve decided to do a short section on some exemplary robotic hacking each day of the competition.

Today’s robot comes from the York College of Pennsylvania. The robot, dubbed “Green Lightning”, features an impressive set of custom made hardware.

We interviewed the team, and got a pretty thorough rundown of their robot with pictures after the jump. Continue reading “Intelligent Ground Vehicle Competition 2010 Day One Report”

LEGO Pick And Place

Turn your volume down and take a look at the brick sorting robot in the video above. It’s built using LEGO and powered by four different NXT modules. It sorts differently colored bricks on the intake conveyor and places them on three output conveyors. The build is solid and was [Chris Shepherd’s] impetus for starting a blog. We appreciate the pneumatic tricks that he detailed in some of his earlier posts such as a compressor, pressure switch, and air tank system. His advice is “build, build, build” and that’s what you’d have to do to perfect a monster of this size and scope.

The Story Of Mr. Stabby

[youtube=http://www.youtube.com/watch?v=XHvXPOSaNbg]

Mr. Stabby was once a broken down bum, sitting on the curb, waiting for an eternity in the city dump. Luckily, someone found him and brought him to the NYC Resistor hacker group. They promptly performed some modifications and brought him back to life.

He’s now a happy go lucky stab-bot with a twinkle in his eye and a skip in his step. His repitoir includes gouging, slashing, and of course stabbing. He can be controlled via a cell phone and has a nifty voice interface.

The video above is from when Mr. Stabby was runner up at the tech crunch hackday.
