6 wheeled rover featuring spot turning. With Video.

About this creation

After a long time I'm back posting a new creation:

This is my first prototype of a rover, which can spot turn and steer normaly.
It has all wheel drive so the lack of differentials between the wheels makes the vehicle hard to steer. The spot turning function activated by three pneumatic cylinders makes maneuvering easier.
The axles are powered by two 9V motors at the rear transmitted via six worm gears.
The motor at the front steers the vehicle.

Steering

The outer wheels flap over to spot turn

This switch changes the direction of the left side motor, so only one wire to the control is necessary.

And here's the video:

Well-constructed and excellent functions! The pneumatic cylinders as switch pole reversers are a great idea, as is the ability to spot turn. With the worm drives, it must have a fair amount of torque. How well can it climb an inclined plane?

It's pretty slow, but quick enough for Mars I think ;-) Nice build btw, and the turning-on-spot technique is very interesting!

Quoting Ape Fight Doesn't look that exciting in the picture, but I know your MOCS always are so I clicked on it anyway - an amazing solution to enable the wheels to operate independently- you are a remarkably talented engineer. It does slide a bit on the floor though (might be the wires) so if there's a V2 perhaps it could be improved with diffs.

Yes, I think in the next version I'll add lockable diffs with a special function, but I'm telling you later.
