Samsung SDS builds its factory robot business on ten outside specialists

Samsung SDS is a systems integrator, and the work it kept for itself in Team REX is integration: choosing which robot goes into which manufacturing process, then handling operation, maintenance and management ^[3]. Five partners build machines ^[4], three build the models that drive them ^[9], two work on data and simulation ^[14][15]. That adds to ten ^[1]. Samsung Electronics owns one of them, Rainbow Robotics ^[8].

The most specific sourcing statement in the alliance concerns hands. Samsung SDS said, explaining why it entered a strategic partnership with Wuji Technology, "When it comes to robotic hand technology, no one can catch up with China" ^[6]. The Wuji Hand actively controls each of 20 joints and weighs under 600 grams ^[5], an average of under 30 grams per joint including the structure ^[2]. It attaches to a variety of humanoid bodies ^[5]. That lets SDS change the robot without changing the hand.

Samsung's own money is in the brain layer. Walden Robotics was founded in January by researchers from the Toyota Research Institute and took a strategic investment from Samsung Venture Investment in June ^[10]. It had been working with Rainbow Robotics before that investment, according to industry sources cited by Sedaily ^[12]. Its robots run on large behavior models, learn new behaviors through actual tasks, and are already deployed at Toyota plants in North America ^[11]. Counting Rainbow, Samsung capital touches two of the ten partners, and the other eight are attached by agreement ^[4].

The report does not include financial terms for the partnership ^[5]. The visible cost is qualification work: five hardware suppliers against three model developers is up to fifteen combinations to validate ^[3], before Config Intelligence's data work and Ndot Light's simulation layer ^[14][15]. Real World, one of the three model partners, is building a benchmark with Nvidia to evaluate precision manipulation in humanoid robots ^[13]. Sedaily describes physical AI as a field where no dominant standard has emerged and capability is scattered across each stage of the value chain ^[7].

SDS could keep all ten and bill a different combination per process, so integration revenue rises with the variety. Or it could narrow within a year to Rainbow plus Walden, and the other eight become references; the Walden sequence, prior work with Rainbow Robotics and then a June cheque ^[10][12], is what a scouting funnel looks like. Or procurement politics pushes Wuji out, and SDS finds out what hands cost from a supplier it has already said cannot catch China ^[6].

I'd expect the narrowing. Holiday Robotics has 155 billion won of fresh Series A money, the largest such round in Korea ^[16]. AiRobot is aiming 170-centimetre bipeds at shipyards and construction sites ^[17], and RoboForce sells TITAN into solar farms, mines and ports ^[18]. The evidence for the first reading would be named process deployments across four or five of the hardware partners, or a second Samsung Venture investment into a partner outside the intelligence three.
