That’s it.\u00c2\u00a0 I’m calling it.\u00c2\u00a0 This Crazy Project Weekend is over.<\/p>\n

And it’s a big truck of fail.<\/p>\n

The biggest problems are the motors.\u00c2\u00a0 They just don’t do what I tell them to do.\u00c2\u00a0 If they did, this would be a different story.\u00c2\u00a0 But I’ve spent over\u00c2\u00a0three days tweaking the motors and the robotics and I just can’t get it working.\u00c2\u00a0 Maybe I can get a Stelladaptor and try tweaking it with direct feedback.\u00c2\u00a0 Maybe I’d be able to do continuous smooth motion if I could have tracked all the bombs properly.\u00c2\u00a0 Maybe I just don’t know what I’m doing.<\/p>\n

At least I was able to identify the playfield elements and get the computer to tell what the next move should be, even if I couldn’t actually get it to make that move.\u00c2\u00a0 The basic recognition and logic was a lot easier than it was for Pong, mainly because trajectories didn’t really matter.\u00c2\u00a0 However, I wasn’t quite able to get the bomb tracking\/prediction logic working, which would have reduced the tendency for the robot to get distracted temporarily and miss a bomb.\u00c2\u00a0 The full tracking also would have made it possible to detect patterns and move smarter.\u00c2\u00a0 I also get the feeling that there’s something already in OpenCV that would have taken care of the object detection and motion tracking for me.\u00c2\u00a0 That library is so big and I’m not a computer vision expert, so I don’t really know what’s there or how to use it all.\u00c2\u00a0 The book and the documentation aren’t always enough.<\/p>\n

And then that virus.\u00c2\u00a0 Stupid virus.\u00c2\u00a0 Make me waste half a day because the bloody computer stops working.\u00c2\u00a0 THAT WAS AWESOME.<\/p>\n

The segmented auto-calibration thing did work.\u00c2\u00a0 I was able to adjust the robot power and swap out gears and the calibration generally figured out the new pixel\/degree ratio.\u00c2\u00a0 If the motors were more consistent, then it probably would have worked better.\u00c2\u00a0 At any rate, that’s a decent technique that I’ll have to remember for the future.\u00c2\u00a0 And I’ll have to clean up the code for it, right now it’s kinda messy.<\/p>\n

In the end, I did not accomplish what I set out to do.\u00c2\u00a0 The best score the robot ever got was 63, and that was a fluke.\u00c2\u00a0 And I didn’t even get close to trying to get it to play on a real TV.<\/p>\n
