If they can stick a LiDAR on this for $1.6k it kind of negates Teslas argument that LiDAR is too expensive for consumer cars. That or it's not really LiDAR on this.
- ralusek 3y agoiPhones have LIDAR, so you could already make that case. I doubt that all LIDAR is the same, though, and there are more expensive solutions for increased range and speed, reliability, durability. Tesla's was more likely motivated by supply chain issues, though, as well as what seems to be a weirdly motivated Elon sticking point that humans can drive successfully with just vision.
- jfim 3y agoThere are different kinds of lidars that use different wavelengths and sensing methods. For self driving car use, the difference between a small lidar that's on a phone or vacuum cleaner and the one on a car would be the amount of power used such that objects far away can be detected, and the ability to operate in automotive environments (noisy power supply, high temperatures, lots of vibration).
- Ecstatify 3y agoTesla’s argument centered around the idea that vision and LiDAR were not complementary. They questioned the reliability of having two different sensors providing conflicting information and the challenge of determining which one is accurate.
- lern_too_spel 3y agoThey don't provide conflicting information. They provide complementary information.

- KRAKRISMOTT 3y agoWeb developers building cars have yet to learn about Kalman filters and basic signal processing.
- tr_user 3y agoAm I taking crazy pills? How does this make perfect sense? The obvious solution is to have more compasses and redundancy.
- squarefoot 3y agoI guess that dog's LiDAR doesn't need to read much longer distances with maximum accuracy at like 150+ Km/h speed; then add certifications et al for automotive use and you probably have very different costs.
- iancmceachern 3y agoWhen tesla was first saying that LIDAR was nothing more than a laser and receiving optics mounted on a spinning hub that spun real fast. Like old those big radar dishes on big navy ships. In the years since, ic and component manufacturers have created solid state lidar. They're basically little electronics modules that cost a few dozen dollars, no motors, etc. The world changes. Better components come along
- _boffin_ 3y agoWhat are some small and lightweight (compatibly) LiDAR on a chip that you’d suggest looking into?
- iancmceachern 3y agoThere are lots, here is one: https://www.analog.com/en/applications/technology/lidar.html?ADICID=pdsr_NA_P104378_Google_TXT_WhatIf-P4&gclid=Cj0KCQjw_O2lBhCFARIsAB0E8B_h8L1Oo91CHwk4Kikghguk0yPggmQ4Xw5VMgDwxzRG5nFXmOM4aaAaAnKUEALw_wcB https://www.analog.com/en/applications/technology/lidar.html...
