  "summary": "SO-ARM101 is the low-cost 6-axis bus-servo arm designed by TheRobotStudio for the Hugging Face LeRobot ecosystem; Seeed sells it as a kit of Feetech STS3215 servos and driver boards, with 3D-printed parts or fully assembled. The kit is built around a leader arm for teleoperation and a follower arm that records demonstrations, which is how most buyers collect imitation-learning datasets.",

Leader+follower: the Seeed wiki configures 6 follower (F1–F6) and 6 leader (L1–L6) servos, i.e. the kit as documented is a leader+follower pair (12 servos). The Assembled Kit page, however, says it includes \"six STS3215 servos\", so it may be a single arm — confirm with Seeed before publishing a per-arm price. No follower-only SKU price was found on Seeed. Design files are on GitHub (TheRobotStudio/SO-ARM100); Seeed calls it open-source. An older \"SO-ARM101 Low-Cost AI Arm Servo Motor Kit\" is cross-listed at $240 on the LeKiwi page. No payload/reach/weight figures on any Seeed page.",
