I want someone to build a collection of small IoT robots that can be customized to perform very small specific actions. The purpose of these robots would be to bridge the gap between analog human actions and the digital world, without requiring that everyone get a "smart toaster/oven/lightswitch/etc". For example, you might have a little robot that can have an attached rotary gripper, for ensuring that the stove top is off. It sits on the stove knob and can turn it based on some input. Or one that can open a deadbolt from the inside. Or one that can brace against a door frame and turn a door handle. You could even include a tiny, low resolution camera that can snapshot the current state of the thing that the robot is controlling. Having these devices be adaptable, with different attachments, would be important to making sure they work in the most situations. Whatever attachments you put on, and how you position them, are unique to whatever analog device you are interested in controlling. Some could brace themselves against the surroundings, some could be screwed into a wall. The key is options.
