Hi Jim,
Did the new 4WD Rover parts show up?

Status: In Transit.
I should have them in a couple days.
Hi Jim,
Sounds great!
Can’t wait to see the new Rover designs.

If you ever make a 6WD rover, it should have a rocker boogie suspension just like the Mars rovers. The actual motors should be inside the wheels, and only the outer wheels need drive. Also, make sure the chassis has more internal volume than the current 4WD rovers, so batteries can fit inside.
Well, my dreams anyways…
Migs,
What Jim needs to design is a Rover with characteristics similar to the new ARMY MULE that is on the cover of the previous Robot Mag.
Just a thought.

Hi TCIII:
Yeah, but as long as the motors are mounted rigidly to the frame, we would have more of the same. An articulating suspension would be great no matter what the vehicle.
Also, I find that I remove the covers of the chassis repeatedly. A good improvement would be to make a “hood” type arrangement that would allow quick access to the internals each time. Also, if 4 or 6 motors plus a drive board fit inside the chassis, not much room is left for batteries. That should also be a consideration.
Some sort of plug to allow recharging a battery inside the chassis from outside it would also be nice.

Hi Migs,
You do have a point about having minimal interior space with the present design.
To get around the battery charging issue, I mounted a chassis power jack and a two pole single throw switch on my A4WD and wired it up through the two pole single throw switch. When the switch is in one position, I can charge the battery and it is disconnected from the motor controller. When it is in the other position, the battery is connected to the motor controller and the Rover is set to operate.

Yeah, that is a great idea, and one I was thinking about. Tonight I have a little free time and so it will be built! -Migs
Jeeez… skynet here we come.
This should be the next rover kit Lynxmotion puts out with turret action. 8) we still have several years before we have to worry about skynet.
Jim (and really all of you who might stumble upon this thread):
Check out these pictures in the link below. Absolutely amazing. Look though this whole thread (backwards and forwards) to see some wicked cool computer graphics of the mars rovers. The guys that do this stuff are really amazing. Tell me what you think.
I would have posted some of these pictures (Ok I’ll post just one so you see the suspension) but then thought twice because they may be copyrighted, and there are so many cool ones to look at:

Jim,
Nice picture! Exactly what I was talking about in the way of a Rover!
A Rover with motors in the wheels is probably not the way to go at the hobbyist level due to the cost. However, a six wheel rover with independent suspension using dog bone shafts to transmit rotary power from a fixed electric motor(s) to the wheels, might be doable for a reasonable price.
Just a thought.
