New Scientist has an article about a DNA bipedal robot that has been created and is taking its first steps. This microscopic robot called "NanoWalker" is just 10 nanometers long and it's made from DNA fragments! Researchers at New York State University say their robot is the first nanoscale bipedal robot to succeed. The robot walks along a kind of DNA track and is able to detach its legs and reattach them further down. The robot is so tiny the researchers couldn't even see the robot actually walk, they had to do experiments to see if the DNA fingerprint they expected from the walk had been created. The researchers hope for their next feat to make the walker carry a load!
