Avoidance Experiments with the POC and Benewake TFMINI

[ppoirier]

Hello Martin
There are 3 models of TFMINI now
What model do you have?

[rickyg32 (RickyG)]

how can you tell what model you have.

[MartyMcFly (MartinKeilloh)]

Hi Patrick it was the 1st TF Mini that came out and thank you for your time

I thinks you are referring to this

How to make the TFMINI rangefinder talk I2C

[image] The Benewake TFMINI is a small Laser RangeFinder that has a lot of potential as a replacement for the Sonar. Its in the same price range as the Maxbotix and it has a range up to 12 Meter indoor and 6 Meter outdoor. It comes preconfigured in binary output at 115200 Bauds and we can change the mode by issuing these commands through the Benewake console (http://benewake.com/en/down.html) or using Realterm: The command of standard output is 42 57 02 00 00 00 01 06 The command of pix …

Hello to all, i have a similar request.If anyone could explain how can i pass the command to revert back to serial once on I2c. Using TFminiPlus. Please, and thanks in advance.

Here is an interesting offer from Benewake for anyone who wants to develop and integrate Benewake product free evaluation activity for developer

hi, i got a question for you. did you have a chance to look at this product:
http://www.mateksys.com/?portfolio=3901-l0x#tab-id-2

i got one board long ago with a F765 sent for evaluation - it is a combined optical sensor and L0X sending data over serial interface.
http://www.mateksys.com/downloads/setup_optic%20flow_in_INAV_rev1.pdf

i am not sure - do you think it is practically usable? L0x is very short range, but they added PMW3901 into the mix. theoretically it could help in optical flow position hold, but how well does that PMW3901 actually work?

[ppoirier]

Hello,
Yeah it is similar to http://www.proficnc.com/all-products/185-pixhawk2-suite.html but on serial.
This particular device is limited to indoor with max height of 1.5 Meter,making them pretty useless,

ST have made their own version of the POC

[ppoirier]

Presently working on a 3D printed POC

[rickyg32 (RickyG)]

Thats cool
Can’t wait to see it working

[Mallikarjun_SE]

I wish Benewake had CAN version of these lidars.

[ppoirier]

Just use a CAN module to interface the TFMINI serial, it works OK

[MartyMcFly (MartinKeilloh)]

Hi Patrick,which can interface module would you recomend please.many thank’s in advance

There was some discussion here:

CANbus for Ardupilot with UAVCAN and UC4H

When you write: I reduced the timeout in the UC4H node somewhat, and I do get clean packets all time, with the TFMini in the default mode (hex output, 100 Hz) Where do I set this ?

here:

Benewake TF02 CAN Bus version and CAN BUS USB Dongle

I did some test in the past, using the BLUEPILL Now there is some commercial units available from these : http://store.jdrones.com/jdrones_uavcan_s/312.htm https://store.mrobotics.io/product-p/mro10042.htm

Range Finder Greyed out

Good day, For this application im using mRo Can node f103 flashed with rangefinder firmware. if you are using the pads under the board you have starting from left: GND-SDA-SCL-RX2-TX2-RX1-TX1-5V Solder the black cable to the GND and the power cable to 5V. Solder the white cable on TX1 pad and the gree n cable on the RX1 pad. In MP just go to RNGFND1: RNGFND1_ADDR: 0 (leave in this way) RNGFND1_ORIENT: 25 RNGFND1_GNDCLEAR: Distance (in cm) from the range finder to the ground ex 5cm to 12…

[MartyMcFly (MartinKeilloh)]

Think I will order one from mRo and give it a try,thank you Patrick

[Dave84 (David)]

Good day, i advice you the mRo can node… just check also when you will receive the version of the firmware… you can use rangefinder on rangefinder firmware and also with the universal firmware.

[MartyMcFly (MartinKeilloh)]

Thank you for this may contact you when it arrives

[Dave84 (David)]

of course yes… for suggestions and advices

[MartyMcFly (MartinKeilloh)]

ordered cant wait to try it have a few uart benewake’s to set up for avoidance
