I would recommend against GRIP. Our team was going to use GRIP initially but I rewrote our processing code in OpenCV using GRIP as a realtime processing agent in the pits than just copying over the hsv, erosion kernels, etc. to the cv code.
  1. GRIP, if ran on the dashboard, requires sending camera data over a second time in addition to the DS which clogs up bandwidth and laptop CPU
  2. GRIP, if ran the RIO, never even worked for us. Gave us some error and resulted in the program never writing to NetTables.
  3. GRIP on the RIO also requires the installation and execution of the Java VM which is quite alot of overhead if you aren't a Java team
  4. There is also the latency of running it on the DS that is amplified on the field which produces visible control lag for the driver or robot code if used
  5. You learn more if you do it by hand! It's not hard. (Getting an mjpeg is a pain though)
