The new MELFA RH-CRH models have a streamlined design
The MELFA RH-CRH series robots are equipped with innovative battery-less motors, which removes the need for periodic battery replacements. This reduces maintenance downtime and costs and effectively eliminates the risk of losing the robot’s positional origin (home position) due to battery exhaustion. As a result, the robots deliver consistent reliability, even during long production schedules or after extended downtime periods.
These improvements to productivity are amplified by a simplified design that significantly reduces the number of components, resulting in up to 69% weight reduction compared to previous models. This lowers installation and facility costs while enhancing long-term operational reliability, continuous operation performance, and overall productivity. Furthermore, the integrated wiring and air piping within the robot arm reduce wiring complexity and simplify setup.
The MELFA RH-CRH series also offers advanced functionality, tracking operations, support for 3D and 2D vision sensors, and force sensing, ensuring precise performance for high-speed tasks. Compatibility with CC-Link IE Field Basic, a gigabit industrial Ethernet network, enables seamless integration into existing production networks and Mitsubishi Electric Factory Automation products, making it ideal for digital transformation in manufacturing. Its optional safety features ensure secure operation in collaborative environments.
“With the MELFA RH-CRH series, we’ve created a solution that delivers exceptional performance and addresses the practical challenges our customers face in modern manufacturing,” said Keisuke Matsumura, Development Section Team Leader. “These robots alone demonstrate our commitment to innovation by helping manufacturers enhance productivity and efficiency. Additionally, when combined with other Mitsubishi Electric’s software advances - such as MELSOFT VIXIO enabled AI visual inspection, the creation of digital twins using MELSOFT Gemini - the expansion of automation, additional cost savings and system benefits can be achieved.”
