Team 488 using Kinect for autonomous navigation

In the off-season, intrepid programmers from team 488 have been working on some fun Kinect projects. Our primary goal - to have an FRC robot navigate a unknown (and potentially changing) environment with no prior knowledge of that environment.

Our setup/process is as follows:
-Kinect running from the robot power supply
-Kinect plugged into a Laptop running RoboRealm
-Roborealm processes the depth image from the kinect and looks for obstacles
-LabVIEW program running on the cRIO queries the RoboRealm server for obstacles
-LabVIEW program determines the importance of the obstacles, based on their distance angle
-LabVIEW program sums all the forces (including the robot's desire to advance) and advances/turns as necessary to progress

In the future, we want to make a number of improvements:
-Replace the laptop with a small form factor (on-board) computer
-Integrate into a field-oriented system to give the robot higher-level goals (going to a specific point, instead of just advancing)

The Kinect has a lot of potential!

John,

This is pretty awesome stuff! Especially with a goal point, I could see a number of past games where this system could be highly valuable. Keep it up.

Yeah, we're hoping the time investment will pay off next season... but it does require a number of things (an onboard computer, good line of sight for the Kinect) that are expensive from both a cost and design perspective.

We hope to have a white paper and some libraries available for consumption before the end of the year, in case anybody else is interested in going down this path.

Overall, it has been a fun project. Has anybody else been playing around with an onboard Kinect in the offseason?

Very cool. The Kinect is an amazingly effective sensor for mobile robots, especially considering its cost.

Now put a A*/D* path planner on there and go to town

Do you think the video processing could be done by a Raspberry Pi, or is it too intensive? If it's not, you should look into some Pis.

Team 422 is planning on doing some sort of image processing onboard the robot next year with a Raspberry Pi. Whether that will be Kinect data or just regular video data has yet to be decided.

This may be a simple question, but I'm not able to pull up my program from 2012 Robot Rumble. When I try to open the file it says "Warning - has been deleted, renamed or moved on disk". I'm not sure how the associations with all the files got lost but I'm hoping there’s a way to restore them. There is of course the program that is still working in the CRIO on the robot, if there is a way to pull that back into the laptop?

Thanks
