What an amazing invention: A wheelchair that can climb stairs unassisted https://www.reddit.com/r/BeAmazed/comments/bsuyry/wheelchair_that_can_go_up_stairs_unassisted/ …pic.twitter.com/rgehJob4BA
Impractical. Going up the stairs backwards won't work in most real-world situations. Perhaps it's time to use four individually motorized wheels on legs, and lidar for scanning the ground? Switching between walking/climbing and rolling would be great. Also high/low rolling mode.
