LiDAR

The skeletal motor mounts turned out pretty well. There’s less material to hold the Azi motor to the tripod plate, and it takes very little force to tip it over.…

As I mentioned previously, the motors get really hot when running at their new speeds. In an attempt to correct this, I made some modifications to the housings for each…

I realized after finishing the board that I used the Arduino’s analog and power pins purely for structural support without any intent to make them usable. I used pin headers…

The Arduino shield I designed arrived from Oshpark about two weeks after I ordered it. There were a couple remnant production scraps on the edges that I had to remove,…

With the lengthened wires, I was ready to start scanning!  I visualized the point clouds with CloudCompare. The equations listed in my previous post are completely wrong. I did several…

I spliced the LiDAR and Motor wires to make them much longer, just about doubling the length of all of them. This resolved the issue I had previously where the…

The stepper driver recognizes a pulse as a 1 step increment. To test this, I briefly used the Arduino tone() command to make the motor spin. https://www.youtube.com/embed/sy7wEGCbqjE The code underwent…

I noticed a minor issue with the redesigned motor 2 housing. When this housing is screwed onto the motor one shaft, it sits crooked and not orthogonal as it should.…

Here’s how the system is wired. You can access the Fritzing files at http://fritzing.org/projects/lidar-motor-circuit The 100uF capacitors next to the motor drivers are to protect the driver from voltage spikes, as…

  In my preliminary tests, I quickly discovered that the 3D printed motor shaft hole on the motor 2 mount (connecting motor 1 and 2) isn’t snug enough. When Motor…
