Abstract: A method of moving an autonomous mobile robot dolly is provided. The method includes positioning a base of a transport trailer under a frame of the autonomous mobile robot dolly. The base carries a lifting plate that is operatively connected to an actuator that is configured to raise the lifting plate. The lifting plate is raised using the actuator thereby raising the autonomous mobile robot dolly to a raised position. The transport trailer is moved from one location to a different location with the lifting plate and the autonomous mobile robot dolly in the raised position.

Abstract: A sun/weather visor for attachment to a safety helmet is provided. The sun/weather visor comprises a visor and an attachment device connected with the visor and configured to attach the visor to the exterior of the safety helmet, so that the visor extends forward of the front of the safety helmet and provides a sun visor for the safety helmet. The visor and attachment device are configured such that the visor will deform or separate from the safety helmet when the visor impacts a solid body, to prevent the visor from interfering with the safety aspect of the safety helmet design.
