Abstract: A method for autonomous map generation by a robot comprising: instructing the robot to traverse a route within an environment in which the robot is deployed; while following the route, causing the robot to collect sensor data to identify features in the environment and to generate an initial map of areas in environment that have been traversed; upon completion of the route, autonomously generating a map of valid areas of the environment by moving throughout the environment while collecting sensor data; while autonomously generating the map, determining that a particular area is potentially invalid by detecting features that are previously unknown to the robot; generating and providing an electronic message to an operator of the robot comprising sensor data of the particular area and a prompt requesting information indicating whether the particular area is valid or invalid; upon receiving a response from the operator, continuing autonomously generating the map according to the response wherein if the particula

Abstract: A method for monolithically depositing a monocrystalline IV-IV layer that glows when excited and that is composed of a plurality of elements of the IV main group, in particular a GeSn or Si—GeSn layer, the IV-IV layer having a dislocation density less than 6 cm?2, on an IV substrate, in particular a silicon or germanium substrate, including the following steps: providing a hydride of a first IV element (A), such as Ge2H6 or Si2H6; providing a halide of a second IV element (B), such as SnCl4; heating the substrate to a substrate temperature that is less than the decomposition temperature of the pure hydride or of a radical formed therefrom and is sufficiently high that atoms of the first element (A) and of the second element (B) are integrated into the surface in crystalline order, wherein the substrate temperature lies, in particular, in a range between 300° C. and 475° C.

Abstract: The straightening jaw comprises a cubical chuck with a plane face end. The face end has an intake element and an exit element of a straightening groove. Between them is an opening arranged perpendicular to the face end. A straightening insert made of hard metal is inserted into the opening loosely but insured against twisting. On the face end, the straightening insert has a of saddle-shaped straightening indentation that connects the intake and exit elements. Because of this structure, long service lives of the straightening jaw and shorter down times of the straightening device causing low production costs are achieved.
