When Use Vision is turned off, visual obstacle detection is disabled. The only available bypass option is Gentle Contact. In this case, when an obstacle is encountered, Yarbo will not slow down upon detection—it will continue at its current speed until the bumper bar makes contact, then perform obstacle bypass.
When Use Vision is turned on, even in Gentle Contact mode, Yarbo will first slow down after visually detecting an obstacle, then continue until the bumper bar makes contact before bypassing.
