The Self-organizing Systems Research Group at Harvard has created a “thousand robot swarm“, named Kilobots, which can self-arrange themselves into shapes and patterns. Each robot in the group moves uses two vibrating motors to move and an infrared TX/RX pair to communicate with its neighbors and to measure their proximity. The Kilobot robot software and hardware design are available open-source for non-commercial use.

Here’s a pool cleaner robot built on ATmega by Davide Gironi:
My replacement electronics it is based on ATmega8 micros.
The project is divided into two parts:
The timer contains the 220 AC to low voltage DC current, and it is out of water, his purpose is to start and stop the cleaning pool robot, which of course is inside the swimming pool.

Trevor Slaton and Dawn Xiang, students from Cornell University, designed this autonomous fire extinguisher that is capable of detecting fires through photo sensors and aiming a water nozzle along two axes to extinguish the fires. Their prototype can detect and extinguish candle fires from about 1 ft. away. Their system uses two servo motors to control the vertical and horizontal position of the water nozzle and a water pump to send out a burst of water from the nozzle. The ATmega1284p microcontroller is used to control the pump as well as the servos.

ElecFreaks will launch a multi-axis unmanned helicopter series: ELF. As the name suggests, this series will be surprisingly tiny. Aimed to design a very compact, portable, able to fly in any place multi-axis helicopter, we will use smart phones app (must support Bluetooth 4.0) instead of remote control. Smaller also means more security and therefore would be more suitable for various occasions and people. If you are a child, this helicopter will be like any other toy of yours. Like always, we will open source all the information. If you are an advanced gamer, this helicopter will be perfect for research and development. If you are just a junior gamer who don’t care details that much, it’s totally ok, ELF got novice mode to allow press-one-key takeoff.

This robot will mow the grass of your garden, staying within a defined area, avoiding all obstacles and working in complete autonomy, automatically charging itself with a solar panel.
In this post we present a robotic lawn mower, powered with solar energy and able to operate just with the clean energy from the sun; this one is a great difference from the commercial projects having a robot in need of a charging station connected to the electrical grid.

After I built the tiny balancing robot using an IR sensor for stabilization, there was a comment on the youtube video about how it would be a good thing for kids to build and learn about PID controls. I thought that was a great idea, the only problem was that that tiny robot was the simplest of balancing robots. It was just an on off switch for telling the motor which way to move. There was no actual PID implementation in that system. So that got me thinking about how it would have been really cool if in one of my classes where I was learning about control theory I had a robot that actually let you see the changes in a PID system in real time. I decided to take it upon myself to create such a robot.

A beautifully designed robotic bartender capable of producing perfect drinks every time, with technology that brings people together.
Barobot is an open source device that pours cocktails by mixing alcohol, soft drinks and sodas. It holds up to 12 bottles and can pour a drink with millitary accuracy!
Barobot features over 1000 cocktail recipes or gives you the option to create your own on the fly. All can be easily accessed via our custom made application on your touchscreen or the user friendly interface on your Smartphone.
Barobots frame – made of either deep black or transparent acrylic glass, comes in either a self assembly kit or an assembled ‘plug and pour’ version. The flat-pack self assembly kit requires no advanced skills or tools (it’s great fun to put together by itself!). Barobot is also illuminated with over 100 individually controlled LEDs that might be set to a number of light-themes or even synchronised to music!

An Attiny85 IR Biped Robot by coretechrobotics.blogspot.de:
Although wheeled robots would be better for beginners I wanted to build a legged robot. Mostly because there were no continuous motors in reach and my attempt to modify a servo failed miserably.
One of the simplest solutions is a biped robot that moves as it shifts its weight. Two servos are needed for the feet and another two to move the legs to go forward or backwards. It is boring to just make the robot walk until the batteries are dead. So I decided to use infrared to receive commands.
