Many lines and labs do not start with the longest reach—they start with whether an arm still fits the existing cell and talks to existing I/O. r-Lite is defined around that reality: controller integrated at the base, 3 kg nominal (5 kg instant), 622 mm reach, and ±0.05 mm repeatability.
The integrated -C layout compresses cabling, cabinet volume, and footprint into an envelope cells can accept, while keeping Modbus-ready I/O, ISO 9409-1 tooling, and web/teach paths—so integrators do not trade compactness for maintainability. For inspection, small-part assembly, and line-side feeding, this tier is often the lowest-friction entry from evaluation to first trajectory.
The r-Lite page uses immersive 3D and blueprints to explain flange, base, and wrist modules—not to inflate spec rows, but so teams can judge at bid stage whether this form factor will remain the default spare template three years out.
If you are weighing r-Lite against r-Core, the question is usually not peak payload—it is whether floor space, interface habits, and the spare path still align five years forward.
