Abstract: An autonomous robot for loading and unloading cargo of a cargo container includes a first vertical member; a second vertical member spaced in substantially parallel relation to the first vertical member; and a cross-member secured to the first and second vertical members in a substantially perpendicular orientation thereto. The robot further includes a first arm and a second arm secured to the cross-member and extending in a forward direction with respect to the robot. The robot also includes means for imparting vertical movement to the cross-member along the length of the first and second vertical members and means for imparting horizontal movement to the first and second arms along the length of the cross-member. Means for imparting motive force to the robot is/are provided. A processing unit is configured to control directional movement, loading, and unloading routines of the robot. A method for loading/unloading the container is also disclosed.

Abstract: A baby carriage handle support, including rotatable arms which fix the handle in upright position when the arms are aligned, uses an interlock which slides along the first arm until the second arm is inserted to the interlock support structure. The interlock support structure includes not only the usual end stop for the second arm, but also a channel projection at right angles to the stop which inserts to the channel of the second arm to provide a more positive locking relationship for the alignment of the two arms.
