mobile robot – Which is a good and cheap 3D LIDAR or other options? – Robotics Stack Exchange

$\begingroup$

There are now some sub and around ~1000USD 3D Lidars available. I wanted to provide an answer for future reference if anyone else comes looking for “cheap” Lidars.

• LeddarTech M16 ~500 USD on Ebay

  • Range: 110 m
  • FOV: 19×3.0 degrees (up to 8.0 degrees depending on model, with 30 m range at that FoV)
  • Refresh rate: 6.25 Hz

• BeneWake CE30 ~1000 – 1500USD on ebay

  • Range: 30 m
  • FoV: 60×4 degrees (up to 132×9 for 4 m range)
  • Refresh rate: 30Hz

• Livox Mid40/Mid-100 ~600 – 1500USD

  • Range: 90m
  • FoV: 38.4 circular (Mid-40 has a 38.4 circular pattern FoV, so its a bit special, but it can technically be used as a 3D lidar, however the pointcloud pattern is a bit different, the Mid-100 is 3 mid-40 providing up to 100 degree FoV)

A really good review on the Mid-40 can be found here. It also explains some of the challenges with the circular patterns, as some SLAM algorithms and fusing algorithms might needs to be adapted to this new pattern, thus not working out of the box.
