Hi,
I am looking to start an after school program using your rover chassis. If I just want the students to program it to run a set course, for example move forward for two feet the turn left and run for two feet, do I just need the arduino uno ?? or Do I also need a motor drive shield??
To confirm, when you say “your rover chassis”, do you mean the DFRobotShop Rover?

If so, it includes an Arduino Uno onboard - you just need to add AA batteries. The motor driver is onboard
You can certainly create timed moves, but the one slight issue is that the two drive motors won’t rotate at exactly the same rpm, so the robot will move in a gentle arc. You can compensate by visually adjusting the speed of one motor so they are about equal, but the ideal way would be to use encoders: robotshop.com/en/encoder-pai … arbox.html
Note that there is an onboard 3.7V LiPo charger which works perfectly with the following (no need to constantly replace AA batteries):

If you did not mean this platform, can you provide a link to the one you are interested in? For example we also offer the DFRobotShop Rover Chassis kit:

In this case, you would in fact need an Arduino microcontroller and motor shield. We suggest:

Hi,
Thank you for the response. Yes I was planning on the DFRobotShop Rover. Another question. Would it be feasible to install a FPV camera on the rover?? If so, would/could the output be directed to a tablet?? I am a bit new at this so any help would be greatly appreciated. Thank you…
Assuming the camera is not large, don’t see why not. It’s meant as a desktop rover so it does not move very fast.

For use with a tablet, you would need a WiFi camera.
Do you think the following would be a workable solution:
7" ultra-thin HDMI FPV monitor 5.8G 32CH Diversity Receiver
Spektrum Ultra Micro FPV Camera and Video Transmitter
The two operate at the same frequency, and the monitor can handle up to 32 different channels in that range, so in theory they should work well together.

Note that for not much more, you can get an FPV headset:

Hi,
Do you know which battery I can use with the Spektrum Ultra Micro FPV Camera and Video Transmitter??
You need a 3.7V LiPo battery. The capacity determines how long it will last. The connector is a bit of a non-standard and normally used only for very small capacity 3.7V LiPos.

If you spot a few which are of interest, we can test if the connector is compatible. Note that polarity is critical because if it’s reversed, you can burn the camera.
