Line Following Robot using AVR ATmega8

One of the most basic autonomous robot you can build is a line following robot(LFR). This type of robot is run over a white surface which has an arbitrary path drawn over it by using back paint. The task of the robot is to run exactly along this painted path. You may note that the surface may also be black(or any other dark colour), in that case the path is a light colour like white. Please watch the following video for a LFR in action. Designing an LFR At minimum our LFR design require the following components. A sensor to detect the line on the surface.(It can be a simple IR Reflectance Sensor or an high end camera!). We will use a simple IR based sensor, it is cheap and easy to build and use. This article describe how to make a line sensor array. A microprocessor to run the code that takes inputs from the sensor and control the motion of robot. We will use a cheap single chip computer called an microcontroller (MCU). A popular family of microcontroller is AVR series from Atmel. A member of the popular family is ATmega8. ATmega8 is chosen because it has just the required amount of resources and is very low cost. The MCU cannot drive the motors (used to actually make […]

Tracked Wheel Robotics Platform

Tracked Robot, Chain Links   Tracked Robot, Chain Links   Chain Links Connected   Metal Connecters   How to connect chain links.   Complete Tracks with 18 links These tracks then can be fitted on the wheels. The track wheel set comes with the chain links, metal connecter and four plastic wheels. For more details check out Track Wheel Set for hobby robotics. Tracked Wheels   A complete mobile platform. The above platform is a four wheel drive, using 200 RPM Gear DC Motors on all four wheels. Bottom View   Gear motor for robots Other wise if you want to control the cost you may use dummy motor in place of two front motors. Dummy Motor Shaft The platform was built over the High Quality Metal Chassis. The Chassis
