"Over the last 6 months or so I’ve been working on a BeagleBoard based robot. The motivation for this was to build a general robotics platform to try out some ideas I have on Simultaneous Localization and Mapping (SLAM) and robust sensor fusion. Here’s the result so far."

"Essentially, the RC car will follow a path drawn by the user on the touch screen as it is drawn in real time. Speed and direction of the car was extrapolated from the user drawn path and sent to the car through radio frequency transmission. We utilized a touch screen taken from an old Palm Pilot, the chassis of an old RC car (including the motors), and a transmitter receiver pair."

"All parts were developed separately. This allowed adjustments in the assembly as well as smaller changes in case the design of one or other part become required. Focus on low cost and use of materials easily accessible in the local market."

"The Seg-bot is a DIY segway clone that costs around $500 to build. It will attempt to keep the rider upright at 0 degrees (level), so if you lean forward it will travel forward to correct its position – the farther you lean, the faster it will go to correct itself."

"Being a little a little bored (although that`s the wrong word) this afternoon, I considered the 3 servos I had in a box after replacing the ones in my robot arm, and came up with the idea of making an ‘insectoid’ robot with them. "

"The goal of this project was to create a robot which could erase written text on a whiteboard completely autonomously, i.e. no human interface. The processes involved in this project included devising a method for the robot to search a whiteboard for text, designing a way to physically move a robot to the text, and enabling a robot to erase the text."

"Conventionally, wireless controlled robots user circuits, which have a drawback of limited working range, limited frequency range and limited control. Use of mobile phones for robotic control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls."

"Good news everyone, another step completed in my window garden. This is just a plain PIC 16F877A microcontroller with a 20MHz resonator and a character LCD. There is also a big photo-resistor for shits and giggles and some neat buttons. I got a dual relay board from eBay to turn the pump on and off, and an extra socket for a light down the road."

"I always wanted a fast way to make PCB prototype before send the project to a fabhouse and wait 2 or more months to see the result. This is why I built this CNC, it’s made from cd-rom parts and was inspired viewing some similar projects on internet."

"An autonomous robot requires both: actuators and sensors. Actuators are responsible for moving and sensors help to measure a physical quantities. Without actuators a robot cannot perform any practical task. If your robot doesn’t have sensors, then it’s blind. In our case, actuators are two motors for moving of the spider. Proximity sensors help to perceive distance to obstacles."
