The Robotic Revolution and Celera Motion's Ingenia Servo Drives

The robotic revolution has arrived as surgical robotics platforms are being widely embraced globally due to the benefits that come with minimally invasive procedures. Celera Motion’s Ingenia servo drives supply small size, efficiency, precision, and flexibility of customization, providing a competitive edge to surgical robot OEMs.

The Challenge

Minimally invasive surgical procedures can be carried out using surgical robots, under the guidance of surgeons operating from control consoles. While reducing the patients' risks is the principal priority, enhancing and improving the accuracy of these surgical procedures is also a key factor. Therefore, robotic platforms must be ultra-precise and reliable. Reducing the overall weight of the system and improving efficiency is critical, so being compact is also an essential feature.

Examples of surgical robotic and medical device assemblies include:

  • Surgical robotic joints
  • Endoscopic tooling and vision systems
  • Instrument drive units for surgical systems
  • End-effector tools
  • Patient positioning systems
  • Haptics for robot-assisted surgery

The Solution

Celera Motion’s Ingenia servo drives are utilized in surgical robotics for minimally invasive surgery. The extremely low EtherCAT latency in combination with its exceptionally small size allows the robot to be compact, precise, and efficient – the major components of success. In haptic robotic systems, weight is essential. A compact, lightweight servo drive can support an overall reduction in the system’s weight.

OEMs have the ability to create a performance advantage due to custom algorithms developed specifically by the customer for the appropriate application. These algorithms can then be implanted into the drive microprocessor and can be as simple as a distinct PID, or as complex as cogging, damping compensation, vibration, or gain scheduling. These are a few of the fundamental traits that address the requirements of the surgical robotics market, opening up a winning platform.

The Benefit

During minimally invasive surgery, instant replication of the movement directed by the surgeon’s console must be achieved in the robot with minimal lag in the system. Celera Motion’s Ingenia servo drives significantly reduce lag, achieving the lowest latencies possible in EtherCAT communications (2 EtherCAT cycles). Combining exceptionally low standby power consumption (1.2 W), and high efficiency (up to 98%), seeks to ensure minimal heat dissipation inside the joint.

Multi-layer, high density design promotes powerful, pioneering, thermally optimized circuitry. Therefore, such highly compact integration enables multi-axis robots to be modular and small while minimizing wiring.

The accuracy, efficiency, compact size, and flexibility of customization in Celera Motion’s Ingenia servo drives provide a competitive edge to surgical robot OEMs.
