This color changing and amorphic creature was invented by DARPA researchers with the goal to create a low-cost silicon based moving bot. The creature uses air and fluid to control its movement and color changes. By using different fluid colors this bot is able to change its color depending on the underlying surrounding. The researches say that this silicon based robot is able to move around 40 meters per hour, or up to 67 meters without the fluids.
One of the actual challenges of this development is to also integrate the power source as well as all mechanisms for producing air and liquid pressure. At this stage of development these parts are controlled from external.
