At QUARK 2010 :: My First Robot :: Under 3$ :: Nano Inspired
This was my first(truly self made) wired robot which was made out of a plastic box with design inspired from Tata Nano made with Rs.150(thats 3$)(excluding mini motors which I already had , but inclusive of the price of the remote) , which instead of having differential drive ,which all participants used had ,"Rickshaw" kind of drive with the rear wheels supporting forward and rear motion and turning with the help of a front wheel.

At Kshitij 2011 :: IIT Kharagpur :: Robots Team up to captivate the "Fugitive" :: Awesome Team Effort
The event was basically a grid based robotics event wherein at unknown nodes within the arena would be these intruders called "fugitives".In order to capture a fugitive a minimum of two robots were required and the robots must surround the fugitive from two directions for the fougitive to be out.The way we handled the task can be summarized as follows:
1. One robot goes around finding for the fugitive.For this we have followed a kind of spiraling inwards kind of algorithm based on the weights assigned to the weights traversed.The robot will travel to the nodes which have lower weights and the nodes which got traversed weights get increased.
2. As soon as the robot finds a fugitive on the way, it stops and signals its location to the other helping bot which basically used a flood fill algorithm to find a shortest path to reach the fugitive.If on its way it found any other fugitive , it would store its location and recalculate its path doing flood fill in real time.
The above explanation is kind of primitive and many modifications and enhancements we done to accomplish the task.
The fugitive themselves were solid cylinders with the top of the cylinder emitting infrared rays in a radial fashion.This gives the flexibilty to identify the fugitive even for a far distance or even if you are running parallel to the fugitive.The power of the radition of IR was limited to a raius of 30cm of one gird away.
