Glancing behind me, I saw a box. As I turned round it changed shape into a machine gun turret and fired bullets at me but I blocked them with a SWAT shield.

I’m a scientist testing new robots in a secret lab. This latest one, called MMORPH, can change shape.

MMORPH turned into a drone and flew silently behind me. Then it turned into a mini tank and fired bullets at me, but I blocked them again.

MMORPH turned back into a box and turned off. The test had worked perfectly and it was ready to fight in the army.
