Tech For Good: A transformer robot designed for last-mile delivery

CNN's "Tech for Good" hears from Dr. Marko Bjelonic, from ETH Zürich's Robotic Systems Lab and founder of the Swiss Mile robot, who believes automated machines are the key to automating our cities. His four-legged and wheeled robot is able to change shape within seconds, overcome steps and navigate between indoor and outdoor environments. It's hoped the bot, which can travel up to 20 kilometres an hour and carry 50 kilograms, has the potential to serve as a member of search-and-rescue teams in the future.
