I have imagined these with Meccano around year 2012. I am now working on those with my students. In our case they are deployable from a wheel for smoother operations on flat grounds.
You would need the wheels to be extremely strong and you would need them to have an extreme amount of traction. This doesn't seem plausible to my stupid brain. Also you would need to be cut to pieces to be able to climb stairs with this. Also, elevators and ramps exist.
I assume that you turn the robot by moving the left and right wheels at different speeds. How do you synchronize the front wheels to climb the stairs? Like, if you made a 90 degree turn immediately before going up the stairs. I see your comment below about STEP, and that would seem to have the same problem, but even more to synchroize left to right and forward to back, to step appropriately. Unless you slip the wheels somehow to get them in sync, it would have problems. Right? Should I assume that these wheels as shown were never intended to use on a real robot? These were just the testing version before making the STEP robot's wheels? I'm thinking of making myself a small robot to help me transport maybe 200 pounds of stuff on occasion, over soft and irregular ground. Right now, I'm just looking around at wheels, to see how others did theirs. I really like yours, I'm just trying to understand how it would work without destabilizing itself. No one likes their robot and load to tumble down the stairs. At the moment, I'm leaning towards the Michelin airless tire style, or Lockheed tri-star multiple wheel wheel. I don't think the Michelin will give me the desired lift over obstacles. The Lockheed tri-star looks unnecessarily complicated.
seems like good questions. this might be an auxiliary thing which is only deployed when it gets to stairs. otherwise you might have to freewheel one side until it locks up against a stair and the other gets into position. the balance thing does seem like the next major problem to solve, particularly with a tall/heavy load.
@Zachary Bergmann Thanks. The dimension is optimized for various stairs, but there is limitation. Please check STEP for the next version. ua-cam.com/video/l4JqCCiA8cY/v-deo.html

Imagine implementing this in wheel chairs.. amazing design 👏 👌
Thanks!

Hey, nice robot!
very practical ...
좌/우회전했을 때, 바퀴의 동기가 안맞는 문제점을 어떻게 해결하셨는지 궁금합니다

안녕하세요 충북대학교 기계/전자 공학과에 재학중인 안정수라고 합니다.
졸업 논문에 레퍼런스로 참조해도 괜찮을까요?
작품이 완성되면 저도 유튜브로 공유하도록 하겠습니다.
ieeexplore.ieee.org/document/8915800 이 논문 참고하시면 됩니다. :)
interesting !
Can the robot go down stairs ?
Thanks! The robot can go down but it needs more research to be more stable. :)
Yes, but I doubt it can carry much weight up the stairs. Also, how do you account for the millions of variations of staircase treads?

@@RoDEL_HYU maybe you can try building something that can change its size to suit the staircase
Sir what are measurements of the wheel I want to make the project myself
