I am building an inspection robot to go under vehicles for a class project of mine. I have no experience in robotics or ever building anything like this. I need the vehicle to support 10 pounds, and travel at around 1 ft/min. While talking with some people, this is the parts list I came up with:
quantity 4: 313 RPM HD Premium Planetary Gear Motor
quantity 1: 2x30 roboclaw motor controller
Quantity 1: NiMH Battery (12V, 5000mAh, XT30 Connector [MH-FC], 12-1)
Quantity 1: XT30 Lead (MH-FC, 300mm Length)
Quantity 1: 12V NiMH / NiCad Smart Battery Charger with XT30 Connector
Quantity 2: Black Revolver Wheels
Quantity 2: Leopard Off-Road Robot Tires
Quantity 2: 12mm Hex Wheel Adaptor D, 6mm Bore
Quantity 4: Aluminum Motor Mount E
Quantity 2:90 Degree Quad Hub Mount
Quantity 1: .4375"L x 6-32 Zinc-Plated Alloy Steel Socket Head Cap Screw
The total cost for these items (from servo city), along with an arduino board and a usb wireless transmitter for an xbox controller puts us over budget. Does anyone know if any of these items could be exchanged for something cheaper? I was thinking changing the motors and the motor controller since they seem like they could be over kill, same with the tires. Could anyone recommend some alternatives? I was looking at the L298N drivers, but I am not sure if they would be compatible with this build. Any recommendations would be appreciated since I am really in over my head with all this since I do not have the background knowledge for this lol. Thank you to anyone who helps!!
