Quadruped Robots

Quadruped robots are four-legged, robot-native machines designed for mobility across uneven terrain and complex environments where wheeled or tracked robots struggle. Inspired by animal locomotion, they combine electric actuation, sensors, and AI to perform inspection, surveillance, mapping, and payload transport. Unlike humanoids, quadrupeds are optimized for stability and agility outdoors and in industrial sites. They are increasingly used in defense, mining, energy, and research deployments.

Charging & Energy Considerations

Quadrupeds typically run on swappable lithium-ion batteries with runtimes of 60–120 minutes. For fleet operations, docking stations and spare batteries are essential. Outdoor deployments may require portable charging kits or solar-assisted micro-stations. Power efficiency remains a key constraint limiting continuous use.
