Ingenia provides servo drives for surgical robotics applications mostly focused in Minimally Invasive Surgery. In these applications, the ultra-low EtherCAT latency and the tiny form factor of the servo drives are some of the key factors for succeeding.
Ingenia has successfully integrated servo-drives in complex surgical robots where the highest accuracy of motion is required.
Our technology background has been designed to fulfil the specific demands of surgical robotics applications. Some of the usual key features are:
In some haptic systems for Surgical Robotics, like for example in surgeon consoles, the light weight of the servo drives is an important requirement. We make sure to minimize the components assembled in our products in order to decrease their weight down to the absolute minimum while still satisfying our customer’s needs.
Getting rid of big cabinets for the electronics and integrating all the servo drives inside the robotic joints can be possible only if the electronic designs are optimized for reducing space and adapting to the specific form of the joints. With the buried-via multi-layer technology it’s common to find 16 or even 32 stacked layer designs embedded in a nail-size servo drive. This high level of compactness and integration allows the multi-axis robots to be modular, more efficient and minimize the wiring.
Our customer’s know-how is important for us, and that’s why Ingenia can offer an open space in the microprocessor for embedding custom algorithms developed by the customers. These algorithms could be as simple as a specific PID or as complex as vibration, cogging, damping compensation or gain scheduling.
In surgical robotics applications, the movements & decisions of the surgeon’s console must be instantly replicated in the robot avoiding any potential lag in the system. Our servo drives minimize this effect by offering the lowest latencies possible in EtherCAT communications (2 EtherCAT cycles).
The very-low standby power consumption ensures that in any given case that the robotic arm touches the patient’s skin, it will be cold enough to avoid any kind of injury in the patient’s skin & tissues while still maintaining the highest efficiency when the servo-drive is working. Ingenia’s drives have an optimized standby power consumption down to 1.2 W per axis while keeping the efficiency up to 98%.
We protect our electronics implementing the required functional safety mechanisms in each application. STO has been successfully implemented and certified in some of our off-the shelf products.
