Mecanum wheeled rover

Hi,

I just took my mecanum rover for its first outside drive.

Axles are taken from this:

Controller is a Mateksys F405-STD with a Mateksys 3-6s (9-27V) PDB. The rover runs on 2s, but the PDB is working without a problem.
A Raspi W zero is used as a companion computer, running mavlink-router and motion, but it is too slow to be useful. I will replace it with a RPi 3B+ soon.

That is way cool! Congratulations and thanks for sharing!

Looking great! I guess we need a new Omni setup to support this or does one of the existing Omni setups work?

Hi Randy,

the omniX frame type is working fine for mecanum wheels. The rollers on the wheels are angled 45°, so it is the same as an omnix rover with the motors angled 45°.

@count74, ah, excellent! thanks for this!

@count74, i love this project, I love mecanum wheels, but often I’ve been thinking what does this setup improves in autonomous rovers compared to “tank” systems?

Also, I would love to know your setup with the smart port telemetry, in not able to setup an arduplane telemetry via smart port with the same board…

Right now it improves nothing, because the lateral movement is only supported in manual mode. It is just great fun driving a omni rover.

I saw your thread about your problems, but I am afraid I cannot help you. I just copied a model setup in my Taranis and that model was using smart port telemetry with a pixhawk. Being the lazy a** that I am, I did not remove the script. I also never noticed that the taranis voice is audible in the video…

On topic of mecanum, assuming that ardurover supports it, how will it make advantage of it? I always wanted to avoid the oscillations trying to adjust a straight path, but cannot figure out any other situation where mecanum becames handy that are not too specific or complex.

On topic of the telemetry, just want to know how is the wiring done in the FC, and the telemetry outputs parameters.
