MELFA ASSISTA RV-5AS-D
Mitsubishi Electric's entry into collaborative robotics — a 5 kg, 910 mm reach cobot with integrated safety monitoring and force-limited contact that works alongside humans without fencing.
Full specifications
Performance
How much it lifts, how far it reaches, how precisely it repeats.
- Payload
Maximum mass the robot can carry at the wrist flange, including the gripper/tool. Higher means it can handle heavier parts.
- 5 kg 17th pct in class
- Reach
Maximum horizontal distance from the base axis to the wrist — defines the size of the work area. Higher means a larger envelope.
- 910 mm 36th pct in class
- Repeatability
How close the robot returns to the same taught point on repeated tries (ISO 9283, ±). Lower is better — tighter precision.
- 0.02 mm 74th pct in class
- Axes (DOF)
Number of independently driven joints / degrees of freedom. 6 is standard for articulated arms; 4 for SCARA/palletizers; 7 adds elbow redundancy.
- 6
- Max TCP speed
Top linear speed of the tool centre point. Higher means faster cycle times.
- 1,500 mm/s 40th pct in class
- Wrist torque
Allowable torque at the wrist axis — how much twisting force a tool can apply. Higher handles bigger/offset tools.
- 12.8 N·m 24th pct in class
- Wrist inertia
Allowable moment of inertia at the wrist — how much rotating mass it can swing without overload. Higher is more capable.
- 0.34 kg·m² 12th pct in class
Motion range & speed
Per-axis travel limits and rotational speeds.
Motion range and maximum speed per joint.
| Axis | Range | Max speed |
|---|---|---|
| J1 | -240° to 240° | 124 °/s |
| J2 | -148° to 148° | 124 °/s |
| J3 | -150° to 150° | 124 °/s |
| J4 | -200° to 200° | 297 °/s |
| J5 | -120° to 120° | 356 °/s |
| J6 | -200° to 200° | 360 °/s |
Physical
Size, mass and how it mounts.
- Robot weight
Mass of the manipulator (arm) without controller. Lighter eases mounting and mobile use; heavier often means stiffer/higher payload.
- 23 kg
- Mounting
Orientations the robot can be installed in (floor, ceiling/inverted, wall, tilted, mobile base).
- floor, ceiling, wall
Power & controller
Electrical supply and the control cabinet that drives it.
- Power supply
Required input voltage / phase for the controller.
- 3-phase 200 V AC
- Controller
The control cabinet / unit that runs the robot.
- CR800
Environment
Conditions it can operate in — dust, water, temperature, cleanliness.
- IP rating (arm)
Ingress protection of the body against dust/water (IEC 60529). First digit = dust, second = water. Higher resists harsher environments.
- IP40 2th pct in class
- Operating temp
Ambient temperature range for normal operation.
- 0 to 40 °C
- Cleanroom class
ISO 14644-1 cleanroom rating the robot is certified for. Lower number = cleaner environment.
- 5 ISO 0th pct in class
Safety
Standards met and collaborative-operation capability.
- Collaborative
Whether the robot is designed to work safely next to people without fencing (power-and-force-limited).
- Yes
- Safety standards
Certified safety standards (ISO 10218-1, ISO/TS 15066) and functional-safety level (PLd/PLe, SIL2/3).
- ISO 10218-1, ISO/TS 15066, PLd Cat.3
- Collab features
Collaborative safety functions: power-force-limiting, speed-and-separation monitoring, hand-guiding, safety-rated stops.
- power-force-limiting, speed-and-separation-monitoring, safety-rated-stop, hand-guiding
- Cert. cobot payload
Payload at which collaborative (force-limited) operation is still certified.
- 5 kg 16th pct in class
Control & software
Programming, languages and ecosystem.
- Programming
How the robot is taught: pendant, hand-guiding (lead-through), block/flow-chart, scripting, offline simulation.
- teach-pendant, lead-through, offline-programming
- Languages
Native robot programming language(s) — e.g. KRL (KUKA), RAPID (ABB), URScript (UR), INFORM (Yaskawa).
- MELFA BASIC VI
- Teach pendant
The handheld programming/jog device supplied.
- R87TB / R56TB pendant
- Simulation
Offline programming / simulation software for the robot.
- MELFA-Works (RT ToolBox3)
- Offline programming
Whether programs can be built and validated offline in a digital twin before deployment.
- Yes
Connectivity & I/O
Signals, fieldbuses and tooling interfaces.
- Fieldbus
Industrial networks supported for PLC/cell integration (PROFINET, EtherNet/IP, EtherCAT, Modbus TCP, CC-Link, etc.).
- PROFINET, EtherNet/IP, CC-Link IE, Modbus TCP

Safety certifications
- ISO 10218-1 — the primary industrial-robot safety standard covering design and construction requirements
- ISO/TS 15066 — the safety standard for collaborative robots working near people (force and speed limits)
- PLd Cat.3 — high safety-integrity (PLd) with a dual-channel architecture that tolerates one fault without losing the safety function
