To build this project you need to answer two important questions:
First, How to use solar to power the Robot?
It is fairly easy to implement, just buy one electronic toy car and Install PV cells at the top of it. Connect these cells to the rechargeable batteries.

Second, How to implement path finding in your vehicle?
Path finding is a technique to move robot from point A to point B avoiding any obstacle in the path. We can many different techniques for that but the most popular one is to first make our robot familiar with the surrounding and then robot can use surrounding information in Path finding. This technique is very old and is not useful in challenges where robot doesn’t know anything about the surroundings. So, to it more, I am giving you some links of robotics path finding methods.
