Keeping ease of understanding in mind, this technical synopsis has been divided into the following modules:

The primary objective of the Project is the development of an autonomous micro-controlled land vehicle with the inherent ability for absolute collision avoidance. It will have the forte to navigate from a pre-determined static point to a desired location, expertly evading obstacles in its path.

Our design incorporates 5 static obstacles, placed on a level surface.

The spirit of the Handy Board is the micro-controller MC68HC11A1FN, mounted on a PCB, with interfacing circuits for 8 analogue, 9 digital I/Ps and motor O/Ps. MC68HC11A1FN has been conscript on account of its outstanding features such as, low power consumption and high performance operation at bus frequencies up to 4 MHz, sophisticated on-chip peripheral capabilities, a fully featured interrupt system, powerful bit-manipulation instructions, easily available compiler and flexibility.

4 Dig, 7 K sensors, 2 at the front and 2 at the rear sides, have been incorporated. The microcontroller is interrupted when an obstacle is encountered, and depending on the sensor I/Ps, control is transferred to the motors, which facilitate turning of the rover in a pre-defined direction. The motors are bi-directional DC motors,9 V, 300 mA, 5.5 kg-cm, pre-geared at 5 rpm. 2 infra red sensors, used at the sides have 6" sensitivity and the 2 behind have 8" sensitivity. Shaft encoders, having holes , enable us to number of pulses, thereby controlling the distance traveled.

Our power requirement being 21.6 V, we use 18 X 1.2V nickel-cadmium batteries, distributed as 8 X 1.2V (9.6V) for motors and 10 X 1.2V (12V) for the sensors. 20 Ni-Cd rechargeable batteries have been used to supply uninterrupted power to the motors and controlling circuits.
