Servosila: Robotics, Motion Control & AI

Listen to the sound of 32 000 RPM This little electric turbine makes roughly 535 revolutions per second under the control of a Servosila SC-60R controller. Medical applications often require high-speed motors. There is a section in the datasheet that gives rules of thumb that help select a higher-speed motor for use with the SC-60 controllers. Although SC-60 controllers are primarily intended for servo applications where the motors have to move rather slowly, but with the highest precision possible, the SC-60 demonstrates an improved performance when driving higher-speed low-inductactance motors such as the one shown in this demo. Low inductance motors are notoriously hard to drive reliably. It turned out that features introduced in SC-60's design due to requirements of precision servo control improved performance at the higher speeds as well.

New Servosila SC-60 brushless motor controllers are now available for purchase. The new controllers bring up to 45A (30Arms) nominal motor current while sharing the same form factor as the venerable SC-25 controllers, thus providing an in-place upgrade capability (datasheet). The controllers come in two form factors, a rectangular (SC-60R) and a circular (SC-60C) one. This time, the circular version has a smaller diameter and comes with a central inner diameter specifically designed for passing rotating shafts or cables through the board. The SC-60 controllers support a wide range of encoder interfaces (BISS/SSI, SPI, Quadrature, PWM) thus making them ideal for actuating powerful high-precision servomechanisms such as robotic arms or sensor pan-tilt-roll mechanisms or traction motors. The controllers provide an open CAN/CANopen and an open USB control interfaces and come prepackaged with open-source sample software code that utilizes the interfaces directly without using any closed source libraries.

Servosila Brushless Motor Controllers are used to actuate gyro-stabilized payloads rather often. So, a simulated pan-yaw-roll device is prepackaged into Servoscope software to help test and debug gyro-stabilization algorithms. The simulated device precisely reproduces a CANopen interface of the brushless motor controllers. This facilitates software testing and troubleshooting as well as integration of such payloads into target platforms.

Servosila Motion Controller is embedded software that acts as a Whole Body Controller for modern multi-axis robotic systems such as quadrupeds. The software runs on Linux, Windows or MCUs such as STM32. Complex motions and behaviors are defined in G-code language. It turns out that G-code texts are well suited for use with generative AI techniques such as LLMs.

Servoscope software comes with a feature-rich 3D simulator for robots and CNC machines. Load your robot's CAD model into Servoscope and test your control software with a virtual robot just like with a real one! The simulation software comes free of charge with Servosila Brushless Motor Controllers. Several 3D models are prepackaged into the simulation tool including a Robot Dog.

A higher-torque model of Servosila harmonic reducer designed for CNC grinding machines is held in the hands of a Servosila engineer. The harmonic reducer is used in CNC grinding machines employed in an aircraft engine manufacturing process. This is the largest model designed and manufactured by Servosila so far. The total weight of the reducer is 5.5kg. The reduction factor is 100.

Servosila SKT-21-100, harmonic reducers optimized for robotic arms. The reducers feature a narrow and compact form factor well suited for robotic servo actuators. The reduction factor is 100:1. Nominal torque is 28Nm.
