Class definition
An industrial robot is an automatically controlled, reprogrammable, multipurpose manipulator, programmable in at least three axes, fixed in place or fixed to a mobile platform, intended for industrial automation. IFR recognizes articulated, cartesian/linear/gantry, cylindrical, spherical, parallel/delta, and SCARA kinematics. [A1]
Articulated collaborative arms
Three same-class 6-axis collaborative arms. “Maximum TCP speed” differs by safety mode across vendors and is qualified in each cell. Each column is filled only from that vendor’s own sheet: UR20 from the tech sheet, GoFa 12 from the ABB CRB 15000 product specification, CRX-10iA from the FANUC CRX brochure. A blank cell means that vendor does not publish the axis, not that the value is unknown to be small. Payload boundary conditions are kept on the payload row — UR20’s 25 kg and GoFa’s 14 kg both require a stated pose. SCARA and delta arms have different reach and payload meanings and stay in their own tables below.

SCARA
Four-axis horizontal articulated arms. Repeatability is stated per joint on the vendor datasheet, and J4 is an angle while J1–J3 are millimetres, so they never share a row. Motion range carries the vendor’s own maximum speed for that axis. The two FANUC sources disagree on SR-12iA J1+J2 repeatability; both figures are printed rather than averaged. This table is SCARA only — delta arms are below and are never merged into it.

Parallel / delta
Ceiling-mounted parallel-link arms. Payload is at the wrist. A delta’s working volume is a cylinder, so reach and work envelope (Ø × height) are separate rows and the cylinder figure is never printed as a reach radius. The FANUC America data sheets and the current FANUC delta brochure disagree on repeatability; both are printed. M-2iA/6H is absent from the current brochure, so its brochure-only rows stay unfilled instead of borrowing a sibling’s value. SCARA arms are a different kinematic class and stay in their own table above.
