This last season has been a challenging year for all Vex teams. Nonetheless, we should look out for the future and what it holds. Covid-19 has been detrimental to VAIC's pilot year. Teams that had registered haven't been able to meet up as they could have in previous years. Still, that doesn't mea…

We simply need a way to see around. When our VAIC team first considered how to approach this game that exact question was raised. Without knowing about the goal states and robot positions of both alliances you’d quickly end up with unplanned or messy outcomes on the field. If you don’t crash into…

Seems like a good time to throw up some stuff from an old robot of mine. You can see the value of a high FOV camera, 360 degree coverage of the field. [image] [image]

Can you post what camera you used? I’ve poked some with the https://www.robotshop.com/en/ydlidar-x2-360-laser-scanner.html to try to distance sense for another project. For these games it’s going to also sense the field elements and there is going to be a blind spot. If you put it up at the to…

I only have a passing familiarity with it, but doesn’t FRC use retro-reflective tape on many of their field elements? Would requiring VexAI bots to have identification plates with retro-reflective tape on all 4 sides of the robot potentially help simplify the friend-or-foe issue? Potentially more …

FRC has really tried to make vision an easy thing, tape helps. VEX could consider IR emitting goals, but that would be an EP nightmare, I now regret typing it. FRC wants your number on the bumpers, four sides, but I like the thinking that VEX could require reflective tape on 4 sides (a 3x3" square…

This year that is true. Next year maybe not. The RECF has been on edge from what I’ve heard. I’ll give you a source in a second.

Yes FRC uses retro-reflective tape which is very effective because your own light source is on-axis with your camera and thus it’s possible to essentially fade out most of the other parts of the image making image processing straight forward. Low cost computing moudles such as Raspberry Pi can handl…

Really just a generic USB fisheye camera.

That is effectively an updated version of the sensor I used here

High FOV is important for VAIC to work well, teams should be able to explore these different sensor options.
