Head to head

Quadruped robots: what does the 20x price gap actually buy?

Three four-legged robots sit at very different prices. This page sets payload, runtime, onboard autonomy, developer access and who may buy side by side, so the price difference can be read against what each one does.

In a robotics lab, a yellow Spot, a silver Go2 and a black CyberDog 2 walk a taped carry course one behind another, each with a weight bar on its back: two big red plates a side on Spot, one smaller plate a side on the Go2 and one small disc a side on the CyberDog 2. Spare plates wait stacked on the mat.
