After 10 years of debugging firmware, hacking CAD models, etching boards, reworking solder, rewinding motors, the lion kingdom saw an RC golf cart in the field. It was negotiating grass without any problem.

This one has a full transmitter, skid steering, heading hold for $700. They claim at least 18 holes or 4 miles of range but getting 8 miles of range has a $1000 tag. Maybe it goes farther without any payload or more range can be hacked with cheaper batteries. The rigid, smooth wheel design wasn't expected on grass.

This one just has a power assist but no RC or steering.
The remote control is an interesting design. It's very specific to golf needs & emphasizes autonomy. A timer button drives it forward by fixed distances, using odometry. The speed of the timer button is set by a pot on the truck itself. It probably maxes out at 4 mph. Continuous forward & backward use single press buttons to increment the speed. Stopping is a different button & definitely not a matter of letting go. Turning requires holding a button.
It has a passive braking system based on a gearbox. They're probably good old geared, brushed motors.
A separate panel on the truck itself allows odometry movement.
Honestly thought it would be up to the level of brushless, direct drive motors & fully proportional remote control but they're able to charge a lot of money for a
