The robot SPAWN is build under the supervision of Mr. Sartaj Singh during summer 2007.
The robot is well equipped with precise odometers to control the position and velocity accurately.
Two 12V batteries together form the power base of the robot which ultimately gets further
divided into two 5V DC power supplies for Logic Circuits and 12V DC power Supply.
This robotic platform can accomodate a payload of 8-12Kgs while running.There is a provision for LASER-Rangefinder and 
Laptop mounted on the top which acts as a host. The robot is constructed with PITTMAN motors with inbuilt encoders and 
HCTL-1100 , a motion controller IC which is controlling the velocities of both motors.The brain of the robot is a PIC-18F452
microcontroller which is communicating with the host over  UART and controlling the velocities as well.

Since laptops don't come with the Serial ports these days , AVR-USB acts as an interface for communicating with the 
rearboard circuitry ( A USB to RS-232 Interface ).An API is also developed at the host level which provides
provision for the host to control the translation and rotation of the robot. The rotation and the translation
is formulated by PID control.
