MH3 vs MH2 by Mirsee Robotics: Review

MH3 measures 170 x 50 x 40 cm and weighs 75 kg, providing a lighter and more compact frame than MH2's 175 x 50 x 40 cm and 110 kg. The reduced weight of MH3 may facilitate easier deployment in space-constrained areas. Both share similar width and depth at 50 x 40 cm, supporting consistent workspace integration. MH2's added height and mass suggest robustness for heavier industrial loads.

MH3 achieves 3.5 km/h maximum walking speed with indoor SLAM, visual SLAM, and LiDAR mapping for enhanced environmental mapping. MH2 reaches 3.6 km/h using visual SLAM and indoor SLAM exclusively. The LiDAR capability in MH3 enables more accurate 3D mapping in complex indoor settings. Both models support reliable low-speed locomotion suitable for assembly tasks.

MH3 incorporates RGB cameras, stereo cameras, LiDAR, ultrasonic sensors, IMU, gyroscope, force sensors in arms, and temperature sensors. MH2 includes RGB cameras, stereo cameras, IMU, gyroscope, force sensors in hands and arms, ultrasonic sensors, and temperature sensors but lacks LiDAR. The additional LiDAR on MH3 improves depth perception and obstacle avoidance. Force sensors differ slightly in placement, with MH3 specifying arms and MH2 hands and arms.

MH3 supports autonomous task programming and learned behaviors beyond teleoperation. MH2 is restricted to remote teleoperation only. This expanded control in MH3 allows for independent operation in structured environments. Both utilize ROS2-based OS with C++ and Python APIs for development.

Both MH3 and MH2 offer 4 years usable battery life. No differences appear in specified power specifications. This longevity supports extended deployments without frequent recharging. Battery performance aligns with demands of continuous industrial use.

MH3 suits skilled labor augmentation in manufacturing assembly, remote operation in hazardous sites, precision tool handling, and dexterity-focused service tasks. MH2 applies to industrial assembly, remote inspection, hazardous material handling, and service robotics. MH3's advanced control enables more autonomous precision work. MH2 focuses on teleoperated inspection and handling.

Both robots run ROS2-based OS with C++ and Python APIs. MH3 adds proprietary teleoperation software supporting VR and haptic feedback. MH2 lacks this specialized software layer. The shared core enables cross-compatible development.

MH3 and MH2 both include force limiting, collision detection, emergency stop, and collaborative mode. MH3 specifies safe proximity sensors additionally. These features ensure human-robot interaction safety. Common elements support industrial compliance.
