Mitsubishi RV-7FR

Against mid-size six-axis arms like the ABB IRB 2600 or the FANUC M-20iA, the RV-7FR stakes out the compact, high-precision corner of the class. Its calling card is repeatability of 0.02 mm, so it earns its keep where placement precision outranks raw span. Mitsubishi lines it up beside arms like the Staubli TX2-90L and the Epson VT6 that chase the same tight, small-footprint work.

The numbers frame the job. A 7 kg payload and a 713 mm reach give it a modest work envelope sized for benchtop-scale cells. That puts it squarely in assembly and dispensing, where parts sit close and the motion repeats often.

The arm mounts floor, ceiling, or wall, so integrators can perch it over a machine or tuck it against a fixture. That range of orientations pays off in machine-tending cells, where the load door and the operator both compete for the same clearance.

At 65 kg it's light enough to reposition when a line rebalances without heavy rigging, and it runs on the CR800-D controller. It carries an IP40 rating. That mix keeps it practical for material-handling tasks that shuttle parts between nearby stations.

Introduced in 2017, its pitch stays consistent: 0.02 mm repeatability, a 7 kg payload, and three mounting orientations packed into a 713 mm frame. For plants that value precise, compact handling over long reach, that spec sheet is most of the argument.
