Features and benefits

Maximum performance in minimum space

• Slim and compact: A smooth, curved design complements the slim arm and compact joints. The external design is marked by a minimalist, functional design.
• High scalability: The MELFA RV-CR series is useful in various situations, supporting a wide variety of functions and options, such as the tracking function, additional axis control, 2D vision sensor, force sensor, 3D vision sensor, MELFA Smart Plus, and network base card.

Lighter unit
Compared with other robot series from Mitsubishi Electric, RV-12CRL reduced unit weight thanks to its simplified drive system and optimized arm structure, resulting in enhanced load capacity. MELFA RV-CR series robots are easy to integrate with automation cells and manufacturing equipment, and their slim structure makes them easy to handle.

Protrusionless structure suppresses interference with surroundings
In addition to a slim, compact exterior and small robot base, the robot's structure features minimal protrusions to the front, back, and sides, resulting in reduced interference with surroundings when the robot operates. This makes it suited to integration with automation cells and manufacturing equipment.

Simple structure improves ease of maintenance

• Beltless coaxial drive mechanism: Transmission to each axis (excluding the J5 axes for RV-12CRL) is using a coaxial mechanism without belts. The structure's simplification has improved transmission efficiency and reliability. Reducing the number of points for periodic belt inspections has also improved maintenance ease.
• No backup battery: The new HK motor eliminates the need for a battery to back up the robot's internal encoder. This eliminates the cost and effort of regular replacement and the risk of losing origin coordinate data due to battery failure.

Large grippers for various applications
RV-12CRL has a large moment/inertia and an extensive number of inputs/outputs for gripper control, which makes the installation of large and complex grippers possible. This enables the stable transfer of large workpieces using grippers that require many cylinders and pads.

Wiring/piping built into the arm
Signal wiring and air piping, suitable for gripper control, are built in from the base to the forearm. RV-12CRL has two 15-pin connectors at both ends of the signal wires to handle many signals. Connectors and air joints are on the side, making it easy to route the wiring.

Structure supporting external wiring/piping
RV-12CRL has several screw holes on the left side of the main unit to support easy wiring/piping. Internal wiring/piping is pulled out from the right side of the unit, allowing wiring without interference.

Equipped with a high-performance motor

• Pursuing practical performance: It uses a battery-less motor that does not require periodic battery replacement. This allows improved torque characteristics, accuracy, and responsiveness while substantially reducing the size and weight, resulting in much better robot performance and greater compactness.
• Continuous operation performance: Lighter weight and improved heat release translate to improved continuous operation performance.

High-speed wrist axis operation
RV-12CRL has the same wrist axis operation speed as the FR series. This leads to an exceptionally high performance when frequent wrist movements are required, such as workpiece changeovers within processing machines.
