MAGI

Mobile Autonomous Ground Investigator!
A project to develop a versatile test platform for strawberry research. With enough mounting space and power for several robot arms, and the strength to move a small fertilizer tank MAGI acts as an in field research station.

Manual control at CalPoly’s Strawberry Field Day

Manual control via radio allows emergency stop from nearly two miles away, or if you happen to be closer, just take control and drive it like a 1200lbs RC car.

But for the rest of the time, MAGI sports dual RTK GPS receivers, and computer vision designed just for navigating strawberry beds. (Note: GPS drive not guaranteed, stay close by with that E-Stop!)

Here are some YouTube videos of MAGI in action:

This first video was taken just after integrating the vision software with the drive control. Please forgive the video quality my next project really should be a robot that takes better pictures and video than I do. Shown in this video the robot simply turns towards the brightest light in the visual field. I am able to direct it using the flashlight on my phone but you can see once in the middle I lose control when it spots the indoor greenhouse grow lights.

This second video shows a test of the row following guidance system. GPS is only so good, and fields tend to change more often than GPS maps update; so when the robot approaches a row the vision system takes control and lines it up.
