The first plurality of panels includes an input panel, a weight panel and a photodetector panel. The executing includes generating, with the input panel, the input optical signals, where the input optical signals represent an input to the first matrix-matrix multiplication operation of the first layer of the ONN, representing, with the weight panel, the weights of the first layer of the ONN, and generating, with the photodetector panel, output photodetector signals based on the output optical signals that are generated based on the input optical signals and the weights.

Beschleunigungsmechanismus für einen SCARA-Roboter und SCARA-Roboter mit einem derartigen Beschleunigungsmechanismus

Die vorliegende Erfindung stellt einen Beschleunigungsmechanismus für einen SCARA-Roboter und einen SCARA-Roboter mit einem derartigen Beschleunigungsmechanismus bereit und betrifft das technische Gebiet der Industrieroboter, um somit das technische Problem zu lösen, dass während der Drehung eines Dreharms bei einem herkömmlichen SCARA-Roboter eine niedrige Geschwindigkeit zu einer geringen Arbeitseffizienz des SCARA-Roboterarms führt. Die Vorrichtung umfasst einen ersten Antrieb; einen Drehkörper, der mit einer Basis verbunden ist und in dem ein erstes Untersetzungsgetriebe und ein zweites Untersetzungsgetriebe vorgesehen sind; eine Getriebeeinheit, die eine erste Getriebebaugruppe und eine zweite Getriebebaugruppe umfasst; eine Zahnradgetriebebaugruppe, die ein Antriebszahnrad, ein erstes Getriebezahnrad und ein zweites Getriebezahnrad, die der Reihe nach miteinander antriebsmäßig verbunden sind, umfasst, wobei das Antriebszahnrad mit dem ersten Antrieb verbunden ist; wobei das erste Getriebezahnrad über die erste Getriebebaugruppe mit dem ersten Untersetzungsgetriebe verbunden ist, wobei das erste Untersetzungsgetriebe mit einer ersten Getriebewelle verbunden ist; wobei das zweite Getriebezahnrad über die zweite Getriebebaugruppe mit dem zweiten Untersetzungsgetriebe verbunden ist, wobei das zweite Untersetzungsgetriebe mit einer zweiten Getriebewelle verbunden ist. Bei der vorliegenden Erfindung wird die Arbeitseffizienz des SCARA-Roboters durch den Beschleunigungsmechanismus erhöht.
