We have done work with both of those sensors you linked to. HVA 3824 used the Lidar on their bot this year and had good experience with it. We used that long range IR sensor for part of the season, and it worked just like all the other Sharp sensors.
The Lidar will be good to +-1 inch. The IR sensor was not that accurate, but it varied by distance. You need a good calibration curve for the IR sensor which you can produce during the off-season. The Lidar provides the distance over I2C, so no conversion is done in your code.
I will provide a contrary view to some above. Experiment with the technology now while you have the time. Learn its limitations and also work past the problems of getting and processing the data. If you wait until build season to learn a new sensor, it can be too stressful. We buy new sensors in the summer and be sure we know how to use them so we can immediately deploy them if needed in build season.

So that leads me to my inquiry, is LiDAR worth the extra hundred dollars vs an IR sensor? The LiDAR seems to have more distance, but, for example, Stronghold, you really don't shoot from farther than that. Thanks! |
