“With this I have an autonomous robot based on the FRDM-KL25Z board and a chassis from Pololu. It performs line following and maze solving, and can be controlled by a remote shell or controller unit (e.g. with an accelerometer).”

“This was the second robot I made for collective motion research purposes. As you can see, it is vastly simpler, cheaper and easier to build. Of course it doesn’t have nearly as many features or as much potential as robot 1, but I think it is much better for what I’m trying to do.
Here’s a picture of the prototype without the battery.”

“My main objective in this project is to work on core computer vision algorithms which enable the blimp to navigate through its envirnment autonomously. The camera is the most important sensor – it provides continuous live image capture for onboard ‘optical flow’ calculations, a very effective technique for obstacle detection and velocity measurement.”

“This project is my first attempt to make a biped walker — and using only three servos. 3S-1 (for Three-Servo walker One) is modelled loosely after the VStone RB300, as seen in their gallery and discussed in this RoboSavvy thread.”

“Cardbot is a functional robot made from laser-cut corrugated cardboard. It is battery powered and wirelessly controlled over 802.15.4 (Zigbee.)….I had the idea that I could build a kit for a robotic base, itself a press-fit assembly kit, that could also serve as a mobile base for other press-fit constructions.”

“In this post I’m going to first alter a robot arm I had built previously from a beginners kit so that it can be controlled from Arduino. Then I’m going to write a series of posts on different ways to control the robot arm using Processing and other things.”

“Finally I have found some time over the past week-end to enhance my Zumo robot. After I had my line following robot based on the Pololu Zumo chassis and the FRDM-KL25Z, I thought it should be easy and logical to solve a maze. Logical: yes. Easy: not that much. In fact it took me longer than expected. As always, there are a lot of tiny and important problems to solve.”

“This tutorial details the process of building a line following robot. The robot can follow both black and white lines. It uses a sensor array to sense the line and a PID control to follow the line.”

“When I gave a workshop at the School of Art and Design in Offenbach about building digital devices out of cardboard, the students asked me to build a machine as well. I always wanted to own a plotter – so I didn’t have to think too long about what exactly I’d build.”

“This report provides technical documentation for a prototype mobile environmental sensor that integrates with the Urban Tapestries public authoring system — the Feral Robot, version 2. Descriptions of the main requirements, as well as the steps in the hardware/software platform development are presented.”
