I am developing a program for school students to experience a “day in the life of a software engineer”. In the program, the school students will build the ‘mission control’ for a ‘rover’ and then use what they’ve built to guide the rover to a destination. Their role is to build the mission control, mine is to come prepared with the rover (and software engineering know-how). Unfortunately, I know almost nothing about robotics and electronics. But I’m hoping those here can help!
EDIT: A little more detail on the project. The Raspberry Pi will be connected to the internet using 4G, and will have a GPS dongle and a high-quality camera attached. The students will guide the robot from a remote location (well outside the building) to a spot in the building, driving over rough terrain.
I already have the Raspberry Pi. I am keen to purchase the following:
- Dagu Wild Thumper 4WD All-Terrain Chassis, Black, 75:1
- 2 x Pololu Simple Motor Controller 18v7 (Fully Assembled)
I would like to know what else I would need to buy to build the robot side of the project. I understand I will need batteries to power both the Wild Thumper and the Raspberry Pi - but what will I need to buy to power both (I believe they run at different voltages, which I understand means I need to buy something to handle that) for up-to 4 hours? Would 2 x Rechargeable NiMH Battery Pack: 7.2 V, 2200 mAh, 3x2 AA Cells, JR Connector be sufficient? Is there anything else, e.g., wires, other bits, that I would need to buy to build this robot?
I am happy to follow tutorials, etc., to build the robot - just wanting to know that I’m working with the right gear.
Thank you in advance!
