Big Dog

A quadruped robot that walks and carries heavy loads. The robot works as a pack mule to assist soldiers in carrying their gear. BigDog is developed to function as a mechanical mule. The powered autonomous quadruped is capable of carrying significant payloads, operating outdoors, with static and dynamic mobility, and has fully integrated sensing and navigation. Sensors for locomotion include joint position, joint force, ground contact, ground load, a gyroscope, LIDAR, and a stereo vision system. Other sensors focus on the internal state of BigDog, monitoring the hydraulic pressure, oil temperature, engine functions, battery charge, and others. BigDog runs at 10 kmh, climbs slopes up to 35 degrees, walks across rubble, climbs muddy hiking trails, walks in snow and water, and carries up to 150kg loads.

Wildfires have always been a part of human history, but there has been a significant increase in their severity and frequency over the past few decades. And this trend is only set to get worse, with UN researchers noting that wildfire events will become 50 percent more common by the end of the century.
