ARM 7 Based Energy Management and Direction Control in a Solar Powered Robotic Vehicle

Robotic vehicles were powered by batteries, fuels, rechargeable batteries etc. in earlier days. Shortage of nonrenewable fuel in the future is an upcoming global issue, therefore renewable energy resources have to replace non-renewable energy sources. Solar energy is an example for renewable energy resource. Solar tracking method is used to charge robotic vehicles now days. In this work, a robotic vehicle is designed which is powered by two rechargeable batteries that were charged by solar tracking mechanism. Robotic vehicles using only a single battery, cant perform its function when the battery gets depleted. In this work two rechargeable batteries are used one will be in the state of charging while the other will provide power to the robotic vehicle. The robotic vehicle is changing its direction for charging as it move towards the more radiated region, after charging completion it tracks back to its original path. The main components of these robotic vehicles are arm 7, rechargeable batteries, LDR, DC motor and the motor driver. The efficiency of the tracking system used in this work is more, as here fixed tracking method is not used. In fixed tracking method the panel cant move towards more radiated region, the LDR helps as to move the panel towards more radiated region with the help of dc motor.
