Patent attributes
A wireless substrate-like sensor for teaching transfer coordinates to a robotic substrate handling system is provided. The sensor includes a base portion sized and shaped like a substrate handled by the robotic substrate handling system. An electronics housing is coupled to the base portion. A power module is disposed within the electronics housing and configured to power components of the sensor. At least one edge camera is disposed near an edge of the base portion. The at least one edge camera has a field of view that images an alignment feature of the object within the field of view of the at least one edge camera of the wireless substrate-like sensor. A controller is disposed within the electronics housing and is coupled to the at least one edge camera. The controller is configured to obtain an image from the at least one edge camera and determine a location of the alignment feature and provide the determined location to the robotic substrate handling system.
