Almost No Numbers Are Published
The Walker S1 product page describes capability and architecture but gives no numbers. Given that 176 cm, 70 kg, 52 degrees of freedom and 2 m/s are published for the newer Walker S2 in the same family, the S1 clearly has such figures but does not share them on the page. For a plant planning to put robots on a line that is a gap: cycle time, reach envelope and layout cannot be worked out without those numbers.
The Difference Between the S1 and the S2
The two models share the same industrial goal but belong to different generations. The S1's emphasis is software: task planning with a large language model, semantic VSLAM and learning-based whole-body control. The S2's emphasis is hardware and continuity: autonomous battery swapping, a waist rotating ±162 degrees, a 15 kg payload and 52 degrees of freedom. The S2 page also advances the software side with the Co-Agent and BrainNet 2.0. The practical conclusion for a plant is that the S2 has a clear advantage in shift continuity.
Engineering Assessment
The Walker S1's strength is not demonstration but the field: it is reported to work in coordination with other automation on a car assembly line, and the manufacturer correctly names three real problems of industrial use. Against that, the page gives not a single numeric value, which makes technical evaluation impossible. The S2 in the same family both publishes its figures and holds a clear advantage in shift continuity. Our recommendation to a plant evaluating the Walker S1 today is to run the comparison through the S2 and to request a technical breakdown for the S1 from the manufacturer.
