20X5 (M3-M4) is a part of MECHAKO that is composed of twenty components that, when correctly connected to each other, create a self-contained robotic system. It is designed to give users the versatility and scalability needed for a wide range of applications, particularly in service robotics and automated industry. The components include motors, servos, actuators, sensors, touch panels, AI hardware, and software development kits. The system also features a modular architecture that allows for the easy installation and configuration of all components. Additionally, the companions include the MECHAKO Command Center for managing and controlling the robotics system and the MECHAKO Workshop for programming, programming logic, and simulating robotics applications.
