Although this is a first robot built by fritsl a member on LetsMakeRobots. But, I think it is a great DIY robotic for first building. Using Picaxe to drives hacked servos and navigates via ultrasonicย�sensors mounted on a servo. Also shoots “laser” and make sounds.[more]
Puff - The Dragon Enters is a fire fighter robot controlled by Arduino.It consists of 2 geared motors, 1 servo for head scanning, 1 motor with propellor fan, 2 light sensitive Probes.

Puff is able to Put out Fires - He Scans his Head to find the Flames - he orientates towards the Flame - and Blows it out.If he fails to blow out the Fire within 2 sweeps then the “PANIC” mode switches in and he backs away to save himself from frying his “Chips”.Puff is an Arduino based tracked autonomus Robotic Vehicle with “Cliff” and “Obstacle” detection.

With a cheap digital camera , R/C servos and a Picaxe control board you can create your own a simple surveillance robot at home.

I’ve hacked a cheap camera and mounted on a pan / tilt neck assembly. Pictomatix MkII only has 64Mb of non upgradeable camera memory so unfortunately he can only take 25 hi-res pictures. I’ve now made him fully autonomous.

The Nickel-O-Matic robot was designed as an exhibit for the ChiBots booth at iHobby Expo ‘08 in Chicago.The main design goal was to provide a machine that was entertaining to watch and produced a tangible take home item. With inspiration from Rube Goldberg and the penny arcade machines of the 1900s.[more]
A common problem for hobby robotics is controlling the drive level to a motor. Often hacked R/C servo’s are used, but they typically have poor control range. Many micro-controllers don’t have built in PWM or the PWM is very slow and makes for lots of motor buzz. This paper describes an AVR chip and software that converts two easily formed R/C pulse signals (often directly supported by inexpensive controllers like the Basic Stamp) and converts them into a PWM signal suitable for driving small motors.[more]
