Student Innovation - OnionBot: Building a Robot Sous-Chef

OnionBot is a robotic sous-chef that automates pan-cooking tasks, giving you multitasking superpowers so you can focus on culinary creativity. It was inspired by a vision for a robot that softens the onions while you prep the next ingredients!

Interesting approach to including humans without just replacing them! I think this idea has a lot of potential to be included in cookers in the future, very innovative! Nice project

@MimiReyburn you saw it here first! Definitely no reason to replace chefs with robots when it is much more efficient to augment their skills - lots of potential with computer vision. Thanks for your comment!

@bcobley love this project, cooking and engineering is a great recipe, this certainly beats the kettle and Pot Noodle approach that most students choose.
