I wouldn't exactly call it unique, as it has a lot of features found on other robots. However, the overall design is very clean and seemingly robust.
I am, however, wondering about several aspects of the design.
1) How does the fork/grabber mechanism retract to fit within the starting dimensions?
2) Are those custom bumpers with the side rollers? Are they legal?
3) Do you really need all four clippard storage tanks to effectively operate the grabber mechanism? Especially since you still have the compressor on-board?
That's a very nice example of a robot build with 8020 or similar extrusions. Based on the 2nd robot in the background, I am assuming you have a bit of experience with it. We're also using the linear UniBearings for our elevator. They couldn't be any easier to work with.
