A voice-controlled robot that can make you perfect grilled cheese sandwiches on demand has been created by a team of students in the US. 'Cheesborg' is the brainchild of engineer Tayor Tabb, 24, and colleagues, who created the toastie maker at Carnegie Mellon University in Pittsburgh, Pennsylvania. The process begins with a voice command to a connected Google Home smart assistant. The cheesy contraption uses a vacuum to begin to assemble the sandwich -- loading two slices of bread and one slice of cheese onto its conveyor belt. Next, the conveyor moves the ingredients into a sandwich press and closes the lid ready for grilling.
