Break Out The Two-ply, Ecobot III Poops

Imagine our surprise when this article on Ecobot III and the disgusting video above showed up in our feed. The robot can theoretically be self-sustaining forever, so long as it has a food source. Yes, you read correctly, food.

Typical robots relying on grub burn the biomass to produce heat/steam/energy, but Ecobot III actually digests using Microbial Fuel Cells and extracts energy in the form of hydrogen.

The process isn’t very efficient (yet), and of course waste must be excreted, but we’re inching closer and closer to the day our robot overlords are invincible. The project has come to a halt (we can’t imagine why), but you can still read up on the process, and meet Ecobot’s brothers: II and I.

General Purpose Robot Remote

[theGrue] has posted his Robot remote control project for us to gawk at. This box o’ buttons is a parallax propeller brain with some Xbee units for communication. Though it was designed to work with TOBI, his tool carrying robot, he made it so that he could control a multitude of robots with it by flipping some switches on the front of the remote.

Foam Board Servo Driven Arm

July 15, 2010 by Caleb Kraft 10 Comments

[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

June 7, 2010 by Gerrit Coetzee 11 Comments

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

June 5, 2010 by Gerrit Coetzee 19 Comments

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.
