I believe We are not far from making real bumblebee!
After watching the movie bumblebee,I was shocked by the bumblebee for its shape changes between human and a car.
I believe human beings are capable of making real bumblebee,because we are now have the key material for making this amazing thing.This kind of material with the properties of shape memory under certain temperatures,good strength etc.It can be nickel titanium alloy or other shape memory alloys.
Nickle titanium alloy(nitinol) with the ability of undergoing deformation at one temperature, and then recover its original shape up on heating above its "transformation temperature".
In real life, nickel-titanium memory alloys are indeed used in the automotive industry. We envision that if nickel-titanium memory alloys are used to make the outer shell of a car, if there is a traffic accident, the car is sunken and we only need to make the sunken part heated to restore it to its original shape.
What a wonderful thing it would be! It seems that people are fully capable of producing real bumblebees, and it will become what we asked and with any shapes with many functions as you may think.
