Here are two articulation linkages I designed. The first is the articulation type you would see in an articulated transit bus. The secind linkage is a radial articulation - it allows twisting along the radial axis running through two connected units.
These linkages would normally be used only in rovers, but might also find use in a walker.
My question is can these actually be built using the SES parts? They look good in Solid Edge, but I have already had one problem with something that looked good on paper but could not actually be built. If these can actually be made with the SES parts, it would allow some very interesting robots to be constructed.
They can be made using the SES brackets. All SES brackets have a standard bolt pattern. If you can put it together in edge works, I imagine that they can be assembled using the SES parts.
I don’t fully understand the application of your designs. Are they for multi-axis joints?
mike, somewhere in the forums i saw an 8 wheeled rover linuxguy deisgned, ill try and find it, but its incoprporats one of these joints, ah, here we go
Have you every ridden in the middle of an articulated transit bus? The first articulation joint duplicates this motion (up/down and side to side). This is supposed to make going over bumps and such more smooth. For my application, it would allow building a rock climbing rover where the articulation allows the robot to flex at the middle to climb over obstacles it would not be able get over if it were not articulated.
The second articulation is similar, but allows flexing on the radial axis instead of up and down. It’s for a different type of climbing and obstacle negotiation.
I am thinking of a way to combine the up/down and radial articulations with the side to side articulation. This would be by far the most flexible.
Here is the combined articulatlion linkage - it is a full three axis articulaton providing up/down, radial (twisting), and side to side articulations. Now, THIS would allow building a fully articulated rock crawling rover.
Yes of course they can be built. The porplem you found with the ASB-06 not fitting perpendicular to the ASB-04 bracket is unique. It was never intended to be used this way from the beginning.
Well, it’s all good. While correcting the problem you found, I also found a true design problem, which I also fixed. My original design for the wheel towers would not have allowed the wheels to be lowered as I said they could be. I fixed this and now everything is as I said it should be.
