Researchers have detailed a melting spy robot that could one day collect information and then melt into an oily puddle after being exposed to UV light or heat. The design of such a robot is highlighted in a paper currently published on the pre-publication server arXiv. According to the paper, the soft robot could collect intelligence as well as take care of other things that might be needed by such a machine.
The melting spy robot is what scientists refer to as a soft robot, meaning that it is made up of materials that are more flexible than those found on conventional robots. These softer materials allow the robots to be more flexible, and they’ve been proposed for several jobs, including delivering medicine to wild animals and even cancer-fighting robots that can travel to specific parts of the body.
This particular robot was built using a silicone composite that the researchers created. The material degrades quickly when exposed to UV light and heat, making this melting spy robot easy to dispose of when its mission is complete. To test the robot’s efficiency, the researchers simulated a mission where it had to scout an unknown environment and then destroy itself.
The robot could detect temperature readings during its mission and even alert the researchers of those changes. It also utilized photodetectors to sense light from a UV lamp. Once the mission was completed, the melting spy robot moved to a small hot plate heated to 120 degrees Celsius (248 Fahrenheit). The robot then melted into an oily fluid, a transformation caused by exposure to UV light and then the heat from the plate.
This melting robot isn’t the only soft robot we’ve seen showing extreme promise in recent years. Last year, researchers created a robotic slime that used magnets to move and collect objects, allowing it to move through tight areas without causing issues.
