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.

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.

Dave looks at the open source hardware UFactory uARM 4-axis desktop robotic arm kit project available on kickstarter.
This is the first unit produced, and comes with the suction cup head and Arduino Uno board and shield controller.

The Arachnoid Mobile Platform is an open source robotics development platform used to make small autonomous moving robots. It can be either configured as a four-legged robot, or as a two wheeled robot. The PCB board holds all the electronics and mechanical components, and also serves as the chassis of the robot.

Ardusumo is a universal platform to build robots on wheels that can move around avoiding obstacles using infrared sensors and follow routes marked with dark lines on a white background.
We have created Ardusumo to bring young students to the world of robotics: if suitably programmed, Ardusumo allows robots to perform various autonomous movements, it integrates sensors and actuators of various types with wheels and electric motors.
The platform is Arduino based but consists of a single molded frame that is both mechanical and electronic circuit. It has also various possible assembly, thanks to the modularity and versatility of the connections.
The electronic circuit of the Ardusumo robot is very simple: the core is an Arduino UNO board, interfaced with four sensors – three in front and one on the back- and two Sharp infrared radar. The optical sensors are pointed down and used to follow tracks marked on the ground and recognize when the robot is crossing a delimited border.

Since we now have a beautiful robotic chassis, we’re ready to continue our Building A Robot series, and get serious with some motor control. This second part of building a robot is perhaps the most crucial as it will define what type of control we will have over the motors. Ideally, we want a simple method for controlling the motors so that our software is free to do other things.
In this article we will move forward with the Building A Robot series by adding the electronics necessary to control the speed and direction of both motors on the robotic chassis, which we developed in the previous article, Part 1: The Chassis. The two main additions in this portion of the project are a microcontroller and a motor controller IC.

In the heart of the D1 radar sensor is a radar chip based on Ultra-Wideband (UWB) radar technology from Novelda (www.novelda.no). An UWB radar sensor sends out electromagnetic pulses and looks at the pulses that are reflected back. When an electromagnetic pulse hits the wall in the video above, a part of the pulse is reflected back to the radar and a part of it penetrates the wall and is reflected from the cabinet behind the wall.
