Liquid Metal States. Advanced Materials, via the Register
These diagrams from the Advanced Materials journal show stages of the Tsinghua University experiment, which is titled "Self-Fueled Biomimetic Liquid Metal Mollusk", including the insertion of the aluminum "fuel" (b) and movement/fusion of gallium alloy droplets (e).
Travelling Metal. Tsinghua University
This diagram details the journey of the liquid metal traveling around the inside edge of a petri dish filled with sodium hydroxide. Moving on its own power, it can navigate the inside circumference of the dish in less than 10 seconds.
A Little Electric Push. Tech Times
Certain gallium allows can undergo controlled shapeshifting once an electric charge in applied. It might be basic research now, but self healing metals would have a lot of civilian and military applications.
Squeeze In. Discovery News
The liquid metal has been observed to not just to move on its own, but also to squeeze into tight spaces as it moves forward (moving the aluminum component can change its direction).
T-1000. Terminator 2 Judgment Day
If you really wanted to build a robot like Skynet's T-1000 Terminator out of shapeshifting metal at room temperature (and we strongly advise against that), you'd need a substance like Tsinghua University's self powered liquid metal to avoid those embarrassing and inconvenient electrical cords.
