Step 1
Degrees of freedom
Answer
In the context of robotic assisted surgery, the term 'degrees of freedom' refers to the number of independent movements a robotic arm can perform. Each joint in the robotic arm provides a specific degree of freedom. For instance, a single joint can typically provide one degree of freedom. To enhance versatility, robotic arms may utilize different types of joints such as rotary or linear joints, allowing for complex movements in various directions.
Step 2
Machine vision
Answer
Machine vision involves the use of cameras or multiple cameras to automatically inspect and analyze objects and movements. This technology is crucial in robotic surgery, as it assists in providing feedback from the surgical site to the surgeon. The cameras operate within an industrial or production environment and are usually triggered to capture and process visual information during the surgical procedure, thereby facilitating accurate operations.
Step 3
Describe the important role played by stepper motors in the control of robotic arms
Answer
Stepper motors play a vital role in the operation of robotic arms by enabling incremental movement and allowing for precision control. They are designed for reliability of operation, ensuring consistent performance throughout surgical procedures. The motors provide a robust power output, essential for generating the torque required for various movements. Additionally, stepper motors are driven by control circuits, which ensure precise control of the arm's positioning and movements, making them integral to the functionality of robotic systems in surgery.
