I always wanted to have an obstacle avoiding robot. I've now made some sort of lidar sensor based on Arduino for that with an infrared distance sensor TOF. I hope you like it.

@LaughingInfidel 4 жыл бұрын

You could eliminate the slip ring (which will wear out) by rotating a front-surface mirror instead of the sensor. And you don't need a stepper motor. A slow, geared motor powered by a voltage regulator with an optical sensor detecting its position on every revolution would work as well. Cool project. Next do an up/down left/right scanning version that can make a 3D image!

Could try microstepping the stepper motor and only triggering the sensor at each incremented step and only once data is received back, step the motor again . Could easily achieve 3200 data points at the cost of some stop start delay. Cool project👍🏻

Use another TOF range sensor on the rotating head, symetrically. You’ll gather data faster

It looks like there are a place on the rotor for another TOF range sensor on the opposite place for the current sensor.

Important note on the light sensor part number. The one in the video is the VL53L0X, vee ell five three ell Zero ex. The confusing part number has both the letter L and the number zero. For those who are interested in a slightly faster, and 4 meter range, try the VL53L1X. It needs a different software library, but it can use the same schematic and PCB. For those building their own boards, the VL53L0X runs at 2.7-ish to 2.9-ish. It does not work at 3.3 volts. The VL53L1X works from 2.7 to 3.4 volts. For a project that uses 3.3 volts, the 1x doesn't require another voltage regulator and i2c level shifters. Some 3.3volt Arduinos work at 2.8 volts. In my experience, USB ports continue to work with 2.8 volt data lines even though it is out of spec. I assume USB has a much lower noise margin and maximum cable length with 2.8 volt data.

@zachsylvester309 2 жыл бұрын

Instead of counting steps what if you just used time? Since you have a hall effect sensor you could calculate the time the disk takes to rotate. Say we measure one rotation and it takes 5 seconds per rotation. This means that the front will be changing 73 degrees per second. So that means we could do something like f(s)= 73s so if we take a sample at .5 seconds using the time delta since the hall effect sensor has been activated we would get. 36.5 degrees. So depending on how you want your accuracy you can just change your sample rate. But given that the Arduino is having issues with just incrementing a variable maybe this wouldn't help. A raspberry pi pico might be a better fit for this since you could utilize multi-threading. Alternatively, if we know the sample rate we could store the expected angles and times in a dictionary. This would save on having to do the multiplication each time and instead having to look it up from memory. This would look something like this. Say we have a sample rate of once per second we know that our sensor travels 73 degrees per second. so we could say lookup = {1:73, 2:146, 3:219,4:292,5:365} this could then be accessed by the distance function. Obviously, for more accuracy, you would ideally have a larger dictionary with a higher sample rate.

Though it is clear that the sensor will no longer hold the properties of being a LIDAR when an Ultrasonic sensor is used instead of a TOF sensor, will it still work? The only difference will be that u have to play with the speed of light when using the TOF sensor, whereas with the ultrasonic sensor, u gotta play with the spead of sound.

As a building/programming exercise this is great. But there are complete 360° lidars available, for less than 100€, which also have much better specs.

I've never thought of this until seeing this video, but how do we account for the shape of the spinning head causing "inconsistencies". In the video we see the walls curves, since the spinning head is round, so objects close to it will obviously register close, but if we are scanning a straight wall and we may want to accurately represent the environment. How can we correct this?
