Re: Be afraid... Be VERY Afraid

A couple thoughts on the design of what is revealed..

1. I don't think that putting this in a swerve module would be very smart. It is apparent that the small wheel can't be pivoted down until it reaches the center of the assembly. If this were on a pod that could turn the wheel touching the ground would literally be dragged sideways because the pod wouldn't pivot around the center of the wheel as is apparent in the top view. I'm ruling out swerve as this seems like it would probably be pretty suckish in that application. (Unless it only pivots when the big wheel is in the perfect position, again not that great a design.)

2. You only have mounting holes for this assembly on the wheel side which is presumably the outboard side of the chassis. This assembly either nests into another part of the chassis or else I would say that is also a design failure as the entire module would be in cantilever.

3. It appears that the axle that you are using to pivot on is live as it is modeled the same way as the wheel axles. If this is the case you could be doing something interesting where your drive motor also pivots the module, a second motor that pivots the module assists in powering the wheels (never mind), or if these are on a drivetrain with two to a side then the front and back can be chained together via this shaft. There is also very little holding those two halves together if all of those shafts are live. All I see is two standoffs by the motor. Based on the pictures I would try to get a standoff towards the big wheel side of the pivoting assembly.

4. If four of these are going on the Outer corners of a chassis I would be concerned about being able to turn. Your basically running a four wheel drive which picking up some wheels can't really help. Octocanium gets around this with omni/mec wheels. If this is the case your turning will basically stink. (unless you're wide) Unfortuantly, you can't just throw another wheel in the middle and chain off it because it won't switch ratios with the other wheels.

Based on what you've given us I think I see the general intent but I'm not sure that you've thought all the way through everything as it appears here.

I am not afraid.
Regards, Bryan
