Definition: Ventrifixation is a method used in the field of mechanical engineering, particularly in the field of robotics. It involves rotating a tool or an object around its axis to achieve specific movement patterns and speeds. In this context, "ventrifixation" refers to the process of rotating a tool or an object at high speed to achieve desired motion patterns and speeds. This is often used in the design and manufacturing of robotic arms and motors for various applications such as industrial robots, medical devices, and
