“Finally got the linebot working reliably. I’ve uploaded 3 images and a movie. I also included the modified Arduino script provided for the “method 1” servos and “V2 Adafruit_Motorshield” I’m using. My sensor board image shows the original 5 sensors described in your “Arduino Robotics” book, but you’ll notice now only the three middle sensors have signal wires, to match the 3-sensor script you provided. “

“Stubby is an evolving hexapod robot which I am making, with contributions from my 6 year old daughter and a co-worker. I have long wanted to make a walking robot, thanks to shows like Stargate SG-1. While Stubby is not the same, it has been a very entertaining and educational project to work on.”

"In this post, I’ll show how to construct a robot with .NET Gadgeteer and how to control it using a Bluetooth connection from a PC application based on the 32feet.NET library. Let’s start from .NET Gadgeteer part. The base of our robot is the Rover 5 Tank Chassis, that provides two motors that can be easily controlled by the Motor Driver L298 Module."

"If you are a beginner to Raspberry Pi and were looking for a simple hardware project, then look no further. This tutorial will show you to develop a python based robot which avoids obstacles and navigates freely. Obstacle avoiding robots are fairly common and easy to make. Here, you can use this project to add object avoidance functionality to your robot."

"After making some sketches and the templates, started the work, which took me only one afternoon to make the body and one more afternoon to the electronics."

"Wally is a wall following robot that uses ultrasonic (ping) sensors to detect objects in its path, much like a bat uses SONAR to “see” things around it. Ultrasonic sensors are like high-frequency microphone/speakers."

"This bot was designed in Autodesk Inventor, and machined from 5052 alloy aircraft aluminum using a Sherline 2000 CNC and some work from Rapid Sheet Metal. He stands 62cm tall, weighs about 5kg and uses a total of 10x EX-106+, 6x RX-64s, and 8x RX-28s."

"Killtron 7000 is a biologically inspired crab walking robot designed by me and my team at the University of Victoria back in 2011. The success of the robot was determined by how well it can autonomously navigate between several walls and how much weight it can carry. Many thanks to Aaron Gehman, Andy Berry, Tina Hung, Joshua Yin, Eva Sun and Yuto Hori for making this possible."

"The Lawnbot400 is a remotely controlled lawnmower that I built several years ago to mow my lawn. It is basically a push lawnmower attached to a large remotely controlled frame."

"This past week, I made a robotic arm that tracks your hand in free space using a Leap Motion, Arduino, and node.js. It tracks my hand very well. It is able to pick up stuff and set it down with relatively good precision, although there is definitely some room for improvement."
