Bipedal robots have been a tough ask for engineers. Creating a bot that’s steady, self-balancing, and able to adapt to uneven terrain is a tough ask. But, as this newly unveiled bot from Agility Robotics proves, we’re getting good at it. The bot’s name is Cassie, and it comes from a fine lineage of bipedal robots. But what could such a bipedal bot be used for? Well, walking around on two feet may be complex in engineering terms compared to, say, a wheeled robot, but it means the bot can go pretty much anywhere humans can. Rocky ground? No problem! Stairs? Taking ‘em one by one. Agility Robotics suggests their tech could be used to make search-and-rescue bots; to help improve prosthetic limbs or exoskeletons; and, presumably if the bots become cheap enough, delivering packages.
