Has anyone gotten the limelight to detect a powercube? My team wants to know before we buy one to attempt some certain autonomous modes.
Besides the vision benefits, the quick frame rate is especially useful for navigating your way around the field, especially with the scale in the middle.
We use pixy cams and we are able to set it up easily, you don’t need to use a light on your bot at all.
To clarify in case it wasn’t clear, “Limelite” is an all-in-one vision solution that includes a camera, co-processor, and LEDs all in one package.

Hi Everyone,
It looks like preorders have started to arrive at your doorsteps!
Thank you to those who have purchased a batch 2 unit. We are now preparing to start on another batch to keep Limelight in stock.
Many purchasers are curious about power cube tracking. Some of our users have already tuned pipelines to track cubes, but we just pushed an update to make it more stable across different lighting conditions and cube orientations. No testing (as far as we know) has happened in an arena setting, but we hope that our users will post their tuned pipelines as they test in various environments.
As always, feel free to request new features or changes! If you’re tracking cubes, let us know what your tuning process was like.
Here’s a test that was completed after the 2018.1 update. None of our users have tried using a single profile across many lighting environments (as far as we know), but multiple users have reported working cube tracking in their buildspaces.
In the absolute worst-case, it is now very easy to make a copy of a profile that works in your buildspace, rename it to “<profile>_arena”, and make slight adjustments at an event.
We think the bright LEDs make it more reliable since they provide a baseline illumination color (think colored arena lights) and brighten the “dark” sides of the cube.
Horses for courses. The limelight is meant for vision solutions that require processing and does a great job of it. But picking out a yellow cube on a non yellow background is much more in the pixy cams wheel House. Like wise, an ip camera will do just as good a job at sending video back to drive with. It’s the field bandwidth that limits you in that regard, and the frame rate of a limelight won’t help when you’re band width limited.
Limelight does both, and you can even plug-in a usb camera to get a dual-camera stream compressed and sent at a lower fps ;).
Just to clarify, the Limelight camera stream uses less than 1Mbps (out of the 7Mbps limit) when it is streaming two camera feeds. An upcoming update will allow for higher frame-rate options while keeping you well within bandwidth limits.
To be fair, ease of use is also an appealing aspect of Limelite, I like the idea of setting up an entire vision system in an hour and have it just work, instead of having our programming team fiddling with it all season and end up with an unusable solution (IE, what’s happened on the teams I’ve worked with for the last 10+ years).
Oh, I’m not saying the limelight isn’t AWESOME. Just that this year you can probably do what you need just as easily and without the 400 price tag. Heck, I’ve got a limelight in my hand right now so you know I like em.
