Description:

This project is an autonomous robot guided by ultrasound and infrared sensors.
It is powered by four DC motors with gearbox, and steering is controlled by four servo motor at each wheel trailers.
A camera located at the top of the robot, send images to a monitor.

Mechanics:

The structure of the robot consists of a lower platform, where the engine and address, and other top shelf where it is installed wireless camera.
The two bases are 4 mm white PVC united by metal spacers.
In the lower plate is mounted, four engines with gearbox and coupled to them, four servos are mounted over the robot to rotate in all directions.

Electronics

This robot has mounted two printed circuit boards, one containing the electronics of the microcontroller master, model Basic Stamp II, responsible for managing sensors and steering servo, and the other circuit controlled by a PIC 16F84A rotation engine traction with an integrated circuit L293D.

Robot Features:

The main function of this prototype is to explore inland, with the possibility in the future, to adapt
to external environment.
The robot's traction is permanent four-wheel drive with a seized gearbox of a servo, the electronics did not work.
The four actuators mounted to rotate the driving wheels will give us a huge versatility when drawing complex maneuvers.
The ultrasonic sensor, we will send the data for calculating distance, the Basic Stamp II and act accordingly, activating the steering servo or wireless camera.
Infrared sensors side, the robot avoids collision with objects or walls by spinning the wheels of the robot.
