Flexiv Rizon Adaptive Robots
Force-controlled 7-axis arms from ModuSystems' partner Flexiv
About Flexiv and the Rizon line
Flexiv builds adaptive robots: seven-axis arms with force sensing in every joint, so the robot responds to contact the way a hand does rather than following a rigid path. ModuSystems is a Flexiv partner and integrates the Rizon line into automation cells for assembly, polishing, insertion, and lab handling — alone, or riding on a LYNX linear axis or ModuLYNX gantry when the work envelope is longer than an arm’s reach.
Rizon models at a glance. All three are 7-DOF, 1 kHz whole-body force control, 0.1 N force-sensing accuracy, ±0.05 mm repeatability, IP65, any mounting orientation, ISO 9409-1-50-4-M6 tool flange, and run from the Hesper control box (423 × 230 × 230 mm, 11 kg, 100–240 V AC). Rizon 4: 4 kg payload, 780 mm reach (955 mm max), 20 kg arm weight, Ø165 mm footprint. Rizon 4s: 3.5 kg payload, 760 mm reach (990 mm max), 21 kg, Ø165 mm, with a six-axis force/torque sensor (150 N, 3 N·m). Rizon 10: 10 kg payload, 845 mm reach (991 mm max), 39 kg, Ø206 mm.
Rizon with ModuSystems motion. A Rizon on a LYNX belt actuator adds a seventh linear axis — up to 1,275 mm of travel on a single SBA90 — for tending multiple stations or machines from one arm. ModuSystems sizes the rail, the mounting, and the motion program; Flexiv’s software handles the arm. Size the linear axis and get a quote online with ModuSystems AI, or see long-travel belt actuators for what a 7th-axis rail involves.
