I keep stripping pinions on the motors I have. The ones in turbo have bigger shafts where did you get them? Do they have encoders? I'll have a 2nd rover soon so Elroy is going to be running your code with a ZED and Sweep lidar. The new one is on a pixhawk with ROS on the companion computer and cartographer for the slam system. Its the rover in this demo at MakerFaire. Awesome rover. I like the trailer and arm. Nice addition. https://discuss.ardupilot.org/t/best-contribution-for-may-jaime-machuca-and-nick-nunno/18663

Hi Griz, I got them through SuperDroids. They are pretty well built I’d say. You can find the link to them on the BoM page here: https://github.com/dusty-nv/turbo2/blob/master/BoM.md

SuperDroids also has the little I2C encoder board available which attaches to these motors to get the feedback.

Cool yea I need better ones. Going over bumps one will get into the air and spin up. When they come back down especially on tarmac it strips the pinion. It was too heavy before a little too lite now so the outriggers aren't keeping the tires on the ground like they are supposed too. But it really helps with the cameras over moderate roughness. Are you turning the ZED 360deg? If so what slip ring did you use? Supposed to get a S3 lidar to play with soon. From what I've seen so far they are a must have item :) Is there any possibility of running a different os on part of the cores in a tegra? Say one core for RTOS for a flight controller to ensure you never miss an interrupt. I assume its too tightly integrated for such craziness but just thought I'd ask.

The pan/tilt unit is also from SuperDroids, it has it's own slip-ring system. There is Concurrent RedHawk real-time Linux available for Jetson but it isnt priced for the OSS community. In the future we hope to support running other OS on the A9 cores, technically you could port it today from the TRM (but a big effort).
