I am working on a new medium-sized robot and I have been messing around with the nrf2401 radio module with the Arduino. But I have seen online that connection through wifi with the raspberry pi is pretty popular. Wondering which one is more reliable, is it personal preference, pros and cons?
Edit: To make it more clear I guess I want to eventually run some computer vision or a camera at least on it. And I would be driving this about 70% outside.
