Dumb question, kind of unrelated: In the process of building a remote controlled cart to haul small heavy loads offroad. Have no experience in engineering or robotics. Where could one go to learn what's needed, say, starting at the motor/drivetrain? (ex: what kind of motor to use, exterior or interior gearing, how to calculate motor size/voltage/gearing needed to haul X weight up Y gradient, steering geometry, actuators for remote steering, etc)

Interesting that they went with the top-mounted differential version rather than the central gearbox version. I'm guessing it's cheaper. The rockers are also a lot more angular than the real mars rovers to save on needing to bend struts. Very interesting trade-offs to make this buildable with off-the-shelf parts, but I personally like the 3D printable iterations of the same concept ex. [1].

Nice, I contributed to the software for this a while back. Wanted to really get into building my own robot by following the linked resource. Covid happened. Maybe someday.
Anyone here built it?

Has anyone tackled this or adapted it?
I wonder if it would make for a fun summer or semester project to assign teams to various subsystems.

I’m thinking someone could make this run in 3d graphics saving me a few $$

BOM > $1000. Bit too rich for my taste. :/

The licencing isn't as clear as I'd like. LICENSE.txt says it's Apache 2.0 but DISCLAIMER.txt says you need explocit permission to do anything commercial.
