Sistema de Telemetria para Robôs Móveis Manoel - Univasf

ABSTRACT
This paper presents the development of a telemetry system that uses a
remote control car as a mobile robot, which had its electronic board and control
discarded. The system is able to send, via software, commands for the car (go
forward, backwards, to the right, to the left, turn on headlights, honk and change the
speed) and receive information on the environment in which the car is inserted
(distance of obstacles) and on the management of the system (as level of battery and
instantaneous speed).
The system is compound by: control software, which is located in the
computer and is responsible for showing the user commands that can be sent and
information received of the car; and hardware that compound by two electronic
boards, one affixed on the computer and the other in the car.
The software was implemented using the tool C++ Builder and the API
(Application Programming Interface) DCB (Date Control Block) of the Windows,
which accesses the serial port, for interfacing with the interactions of the system and
the user
The hardware project is composed of two control boards, which use the
ZigBee technology for wireless communication. The plate affixed to the car has a
microcontroller PIC16F877A responsible for receiving/sending
commands/information. An embedded program is responsible for managing and
monitoring implementation of predetermined actions. The plate affixed to the
computer sends/receives commands/information in order to interface the
communication between this and the mobile robot.
