Smart Host Microcontroller for Optimal Battery Charging in a Solar-Powered Robotic Vehicle
[attachment=66710]
Abstract
This paper focuses on the design and construction of an optimization charging system for
batteries by means of tracked solar panels. Thus, the implementation of a complete Energy
management system applied to a robotic exploration vehicle is put forward. The proposed system
was tested on the robotic platform an unmanned exploration vehicle specialized in recognition.
The interest of this robotic system lies in the design concept, based on a smart host
microcontroller. On this basis, our proposal makes a twofold significant contribution. On the one
hand, it presents the construction of a solar tracking mechanism aimed at increasing the rover’s
power regardless of its mobility. On the other hand, it proposes an alternative design of power
system performance based on a pack of batteries. The aim is completing the process of charging
a battery independently while the other battery provides all the energy consumed by the robotic
vehicle.
Existing System
Solar based unmanned exploration vehicles are used in some space researches.
The existing exploration vehicle uses static solar panels, which cannot track maximum power
from solar cells. Here we are using a solar tracking system to produce maximum power.
Proposed System
The proposed system uses Master and Slave based Microcontrollers. The Master
controller PIC16F877A senses the light intensity from two different directions using LDR (Light
Dependent Resistors). The panel’s direction is adjusted according to the sunlight direction using
a stepper motor. The exploration robot has two-fingered arm to pic and place the objects. The
robot is controlled using Zigbee protocol. The Battery status will be continuously measured and
sent back to the monitoring unit through Zigbee. The monitoring section consist a PC with
Zigbee transceiver, VB based user interface used to control the unmanned exploration vehicle.
Since we are using solar-based system, power consumption is reduced.
