Abstract: A mobile robot (for example, a robot used for package deliveries, among other purposes) may include a mast with a visual indicator for providing visibility to drivers and pedestrians in the environment proximate to the mobile robot. The mast may produce a large moment arm, which may result in the mast being more likely to break off from the robot. To mitigate or prevent damage to any components of the mast and/or the mobile robot when such a breakage occurs, described herein is an omni directional breakage joint that is used to connect the mast to the mobile robot. The omni directional breakage joint comprises multiple ball and socket joints that provide structural support between the mast and the mobile robot, while simultaneously allowing for a certain movement freedom of the mast and allowing for the mast to easily be engaged and disengaged from the mobile robot without causing damage to any components.

Abstract: An adjustable bracket includes a body of quadrilateral shape that defines an attachment plane for a device, which includes a first adjustment mechanism located adjacent a first corner of the quadrilateral shape, a second adjustment mechanism located adjacent a second corner of the quadrilateral shape, and a pivot. The first adjustment mechanism includes a first passage transverse to the attachment plane, a second passage parallel to the attachment plane and leading to the first passage, and a first moveable member extending in the first passage. The second adjustment mechanism includes a third passage transverse to the attachment plane and a fourth passage parallel to the attachment plane, and a second moveable member extending into the third passage. The pivot locates adjacent a fourth corner of the quadrilateral shape such that the first and second adjustment mechanisms are configured for adjusting the adjustable bracket relative to the pivot.
