What do you think of this LiDAR for drone?

Hi, everyone, in fact I am quite new in drone area, so I wanna ask if I need to equip a drone with a LiDAR for altitude holding and even auto-guide. What do you think of this LiDAR. Does it count? I need some advice. Here is the link in Robotshop.

    ⦁ User-defined ID/IP
    ⦁ CAN – obstacle avoidance mode:
    ⦁ User-defined Baud Rate – to match the baud rate of other devices in CAN bus
    ⦁ User-defined CAN-ID including data ID, heartbeat ID, command ID and config ID – to install multiple CE30-A devices in one CAN bus
    See instructions in CE30-A Datasheet, page 10,Chapter 4.1.4.
    ⦁ Point-cloud IP
    User-defined IP address – to install multiple CE30-C devices in one robot
    See instructions in CE30-C Datasheet, page 11,Chapter 7.1.
    ⦁ Wide input voltage
    The input voltage used to be 12V DC. Now it is updated to 11-25V.

    In case of further questions, please refer to bw@benewake.com.

  • All right. Hope they can solve the problem soon.

    And I am curious about the test of TFmini, the blind area of TFmini is 30cm, that is actually right. Have you set it in a drone? Or what do you use it for? Beyond the 30cm, does it work well? 

    And thank you for your advice.

    The  Lw20 has a waterproof enclosure so it is not possible to solder wires to serial output , you have to send back the unit to a lightware assistance center.

    I  did just a short test  with the  TF-mini , I do not like the fact that under 30 cm , where the sensor is not supposed to work, the manufacturer call it "blind area" , the reading jump from 30 cm to 1,5 meters.
    So do not forget to set the right parameter in range finder parameters.

  • In fact, you donnot need I2C to connect TFseries, and you can weld the end of the wire of TF series to connect to any port as you like. 

    And it may help, you can check the data of TFmini in http://www.benewake.com/en/down.html or contact the e-mail huaxiaocheng@benewake.com for further help.

    I recently bought three Lidars.
    Lightware LW20/I2C , LeddarOne and Benewake TFmini, the last two with serial connection .

    The Lw20 has an interesting feature to drive directly a servo to scan and could be use for obstacle avoidance but beware , do not buy the I2C version because the config sotware with GUI will not work  !

    Lightware promise to find a solution  but I'm still waiting....

  • Thanks a lot. Some friends have the same promblem, I will make them read your blog, it may work.

  • Hi, Luc Maximilien. As far as I know the GUI does work. What is your problem actually, if you can send me, maybe I and my friend research in LiDAR of Benewake may help you a lot.

  • Yes, thank you. But if a drone need auto-guide, I think a LiDAR may help to avoid the obstacle, is it right? 

    Fnoop said:

    Depending on what you mean by drone, and what type of work you're doing, no you don't need a lidar or any other rangefinder.  Rangefinders are useful but not mandatory.  Altitude hold is done primarily by barometric pressure converted to altitude.

  • Hi, what do you mean by compatible? Does it mean the LiDAR does not suit the drone?

    OG said:

    no the compatible  lidar is found https://www.sparkfun.com/products/14032
