Hie all i was wondering what the slowest speed a rover can be set to for navigation? I have a new platform that is meant to go about 4-5km/h (2.5-3.1 mph). would that be too slow for following gpswaypoints or does speed not matter as much?
Thanks in advance
My setup would be
-6wd robot (5mph top speed)
-APM 2.5
-Turnigy 9x remote

Hi. The parameter CRUISE_SPEED sets the autonomous speed of the rover. This can be set in 0.1m/s increments so the slowest the rover can move is 0.1m/s assuming your Rover can go that slow. This is about 0.4km/h.

Thanks, Grant.
Thanks for your reply Grant. i'll let you know of my progress!
That would be great. Love seeing build pictures and videos of rovers in action!
Thanks, Grant.
Here is my current build. It will be undergoing 6wd conversion within 2 weeks or so.

That is a superb build page. Love the detail. Love that you made your own controller! Very nice. Make sure you post when you have converted it to 6WD!
Thanks, Grant.
will do! thanks for checking it out!
I made this last year. top speed is about 0.5mph. Nav works well, just took some tuning.
APM nav controller with an Adruno custom mixer for controlling the 6 wheel steering and crabbing.
Frame is aluminum towel bars and 3D printed plastic parts. Wheels were also printed.
The 3D camera mounted in this pic. has been replaced with a 30X optical zoom camera wiht night vision on a 3axis gimble.
8000mha battery gives about a 4 hour run time. I have done some amazing animal watching with it.
This is somewhat of a replica of the Mars Rover's Rocker Bogie Suspension.
All 6 wheels are always on the ground no mater how rough the terrain gets.
Best of luck with your project. o/

thanks! your project is a great morale booster for mine. sadly my rover does not have suspension but its something i'll add on after i have had some time. i thought speed was a factor but its great to know that thats not the case.
Thanks for sharing your project! Here is mine at the moment. i intend on adding APM once the the datalogging stuff and telemetry is done. Its currently undergoing some serious cosmetic changes:
-changing it to 6wd
-lowering the roof height
-adding a robotic arm
That's a great looking custom rover Mike. Do you have a web page with more details and photos? Are the STL files for the wheels available?
Thanks, Grant.
