What can it be used for

4

Nvm I looked it up. Probs isn’t gonna happen as a safety thing. If teams start shining lasers in peoples eyes (accidental or not) it’s gonna be a problem

Ya ummm I’m not getting it. Knowing the reason u want the sensor can help us discuss the possibility of a sensor that is able to reach those capabilities or maybe find an alternative direction to achieve the results ur looking for

Edit: oops didn’t see ur edit

The difference between that and vex is that u know where everything is going to be on a vex field. Similar results can be attained using tracking wheels for much less effort.

Edit: meant to say position tracking. Tracking wheels are a way to make position tracking more accurate but is not necessary

VEX had already suggested that they might make a LiDar sensor in the future.

Considering that VEX is already taking steps for new sensors, let’s not get ahead of ourselves. They’ve been continuously working on new items, it’ll just be any month where LiDar will be available. By asking “When will _ be available” can likely stress them out and I would rather have a reliable sensor released later than a 1/2 functional device released on-time or early, similar to the V5 system which seemed a bit rushed along with the V5 vision sensor (Not to offend VEX or anything, but the vision sensor seemed rushed alongside the V5 brain and motors. I will bet that if the system(s) were given another month or three, despite everyone’s impatience, we could’ve had a more reliable system).

LiDar is interesting, but I feel vex has better alternatives. I’m personally waiting for the V5 Speaker

If you knew how to untangle cables, there could a vision sensor attached to a motor, spinning around, acting as a lidar

I’ve done that with the sonic detector, just spin 360 one way, spin back the other way. works ok, physically. The sonic one has extremely limited range though, which is maybe fine for competition, I don’t know, don’t do that.

My use case for the Lidar would be to accurately map distances to walls and objects as you move through space. In a known space, the distance to the walls could help recalibrate position. In unknown space , being able to see more than a couple feet away gives you a much better chance of finding a path ‘out’ (where you are simply trying to go as far as you can, and always checking for the ‘horizon’).

Maybe a combination of a distance sensor, and vision sensor would work best.
