The robot is built by the Alphabet-owned Boston Dynamics. It was developed for DARPA under the name LS3, or “Legged Squad Support System”, and it can climb hills, carry weight, and follow humans into battle. It just can’t do it quietly. Rather than aiding Marines in battle, that noise turns the mechanical mule into a dead (and deadly) giveaway. From Military.com: For a military that wants to dramatically increase its robotic soldiers by 2030, this is a setback, but not an insurmountable one. Next time the military asks for a legged squad support system, it should make sure it asks for a legged silent squad support system.
