GRIP (PI) to arduino?

Technical Programming

I’d like to be able to use GRIP running on a pi to send the coordinates of the object being tracked to an arduino. I’m trying to make a small servo gimbal with a Webcam attached to track things in grip.

The idea is that I’m using GRIP as I would on a normal FRC robot but using the arduino in place of the roborio (arduino’s are far more accessible to me than a roborio). This would then function as a test platform for our vision tracking code.

I know GRIP outputs the center of a detected contour via network tables, is there a way for a network enabled arduino to receive these network table values? How else might I go about receiving the data from the pi?

Unless one exists, you would need to write a NetworkTables lib for Arduino. Instead, what I would do is have a program on the pi that reads networktable values and sends them over i2c or serial to the arduino. You can use python and pynetworktables, or some other lib.

You could set up a UDP client on the PI and a UDP server on the Arduino. Then just send the target info as a simple string.
