In-House Revo1 Motors Differentiate 1X

The motor decision matters because it turns a commodity part into a control point for price, safety, and product speed. In humanoid robots, motors are not just parts that spin, they set how smoothly an arm moves, how hard a joint hits, and how expensive each robot is to build. 1X ties Revo1 to cable based transmission and in house manufacturing in Norway, which lets it tune motion for human contact while reducing exposure to the Chinese actuator supply base that gives many rivals a 40 to 60 percent component cost edge.1 2 3 4

• Revo1 fits the product goal of safe home and workplace interaction. 1X describes its motors as quasi direct drive with cable transmission instead of gears, which lowers friction and makes backdriving easier, meaning the robot yields more naturally when it bumps into a person or object.1
• The comparison is not abstract. Chinese robotics makers like Galbot, Fourier, and Unitree benefit from cheaper motors, actuators, and magnets, with Unitree pricing humanoids below $16,000. K-Scale Labs cited Chinese brushless DC motors being 2 to 3 times cheaper as a decisive disadvantage before shutting down.1 3 4
• Most humanoid startups buy major motion components or focus their differentiation higher in the stack, in software, deployment, or system integration. 1X instead is pushing vertical integration down into the actuator layer, alongside its own AI models and teleoperation loop, so hardware iteration and learning data improve together.1 2 5

The next phase is whether in house motors move from technical edge to manufacturing edge. If 1X can pair safer actuation with rising robot volumes through home rentals and the EQT rollout, Revo1 becomes more than a component advantage, it becomes a way to hold margins and performance together as humanoid pricing compresses.1 2
