The WSR-400MINI, a testament to our commitment to innovation and excellence, underwent significant improvements in 2024. Its dimensions were reduced to 12988101469mm, making it effortlessly fit into residential elevators. This enhancement opens up a world of possibilities for indoor glass installation and renovation works in apartment buildings. Furthermore, we have added a standing platform at the rear of the WSR-400MINI, enhancing its versatility and usability. This mini robot is a comprehensive solution for all glass installation needs, boasting features such as a 360-degree rotation, 180-degree tilting, manual side turning of 90 degrees in both directions, a frame side shift of ±50mm, and a extending arm with a reach of 500mm. Its maximum operating height stands at an impressive 3.2 meters. The WSR-400MINI is not just the smallest and most compact robot in the WSR series; it is also a powerhouse of functionality. With a maximum rated loading capacity of 400kg and a self-weight of approximately 771kg (including counterweight), it is built to handle even the heaviest tasks. Powered by batteries, DC actuators, and motors, this mini robot is ideal for dense material handling, transportation, and installation works.
