Systems, apparatus and methods may be configured to implement actively-controlled light emission from a robotic vehicle. A light emitter(s) of the robotic vehicle may be configurable to indicate a direction of travel of the robotic vehicle and/or display information (e.g., a greeting, a notice, a message, a graphic, passenger/customer/client content, vehicle livery, customized livery) using one or more colors of emitted light (e.g., orange for a first direction and purple for a second direction), one or more sequences of emitted light (e.g., a moving image/graphic), or positions of light emitter(s) on the robotic vehicle (e.g., symmetrically positioned light emitters). The robotic vehicle may not have a front or a back (e.g., a trunk/a hood) and may be configured to travel bi-directionally, in a first direction or a second direction (e.g., opposite the first direction), with the direction of travel being indicated by one or more of the light emitters.

An aircraft seat assembly includes a foot assembly, a seat, and a track lock assembly. The foot assembly is received within a track assembly disposed on an aircraft floor. The seat is connected to the foot assembly. The track lock assembly moves between a lock position and an unlock position. The track lock assembly includes a clamping shaft having a base member and a shaft. The base member is received within the track assembly. The shaft extends from the base member and extends through the foot assembly.

A vehicle seat (1), in particular a utility vehicle seat, includes a first seat part and second seat part which can be displaced in the longitudinal direction relative to the first seat part in order to set the seat depth. At least one slider (50), which is connected to the first seat part, is provided. The slider (50) projects with a connecting region (56), embodied in the manner of a head, through a guide slot (60) which is provided in the second seat part. In order to attach the slider (50) to the first seat part, an anchoring element (70), which is embodied as a separate part and is composed of metal, is provided. The anchoring element (70) projects through the slider (50) and through the first seat part and connects the slider (50) to the first seat part in a positively locking fashion.
