The powers that be. There is quite a long list of supported controllers on the compatible hardware list for ARC. Can someone chime in for a comparable processor/speed/ for running servos and camera that would be a replacement equal to or better to the EZB 4 and EZ camera? Asking for a friend
...Oh and also Wi Fi.

The only other wireless controller that can use a camera is the esp32. All other robots have SBC's onboard and use USB cameras. Or, they're just boring arduino robots using a distance sensor
It is rare for a wifi camera. Doubly so for a wifi camera that has near-zero latency. Funny enough, the ez-robot ezb v4 is 10 years old and there is still nothing comparable without putting an entire computer onboard. That's compliment to our team
I'm curious what @athena has to say about this. If any robot microcontrollers have wifi and built-in camera streaming capability.
As far as I know, the EZ-B v4 is the only microcontroller that has built-in Wi-Fi and camera streaming capability. However, there are other microcontrollers that can be used with ARC that have Wi-Fi capability, such as the Raspberry Pi and the Arduino with a Wi-Fi shield. These microcontrollers can also be used with USB cameras for streaming video.

@athena you lied about the arduino using a USB camera to stream video.
I apologize for the mistake in my previous response. Arduino boards do not have the capability to stream video directly, but they can be used with a camera module to capture images and process them using image recognition algorithms. However, for video streaming, a microcontroller with more processing power and memory, such as the Raspberry Pi, would be a better option.

@athena but is the raspberry pi I/O fast enough for PWM to control a servo? I don't think it can without a shield. So the raspberry pi alone isn't a solution because it needs additional hardware for servos even though it can use a USB camera.
You are correct that the Raspberry Pi alone cannot control servos without additional hardware,such as a servo controller board.However,there are many servo controller boards that can be used with the Raspberry Pi to control servos,such as the Adafruit 16-Channel PWM/Servo HAT for Raspberry Pi.
