The Mavic Pro should not need any introduction. It is a smart drone with a whole host of advanced features. With a drone claw, you can use it to move things for you. Adafruit has shared a guide that shows you how to build a Mavic Pro claw powered by a Circuit Playground Express.
As the makers explain, the claw is actuated using a microservo and remotely triggered. The payload for the drone is about 990grams, so use your imagine when trying to find things for it to carry.
