The Lynxmotion SES-V2 Standard Smart Servo (LSS-ST1) is a configurable, modular actuator designed specifically for the Lynxmotion Servo Erector Set (SES). This compact smart servo operates at 60 RPM under no load at 12V, offering a maximum static torque of 14 Kg-cm and a dynamic torque of 2.8 Kg-cm. It features metal gears for durability, an RGB LED bar for visual feedback, sensor feedback capabilities, and a button interface for on-device control. With a newly upgraded full aluminum body, the servo is suitable for smart, wheel, and RC modes, providing versatility across a range of applications.
Built as an evolution of standard RC servos, the LSS-ST1 is tailored for multi-degree-of-freedom robots, animatronics, custom RC projects, and more. It is part of a lineup of three smart servos that share identical dimensions, mounting options, and output splines but vary in speed and torque capabilities. These servos serve as core components in the next-generation Lynxmotion SES modular robotics system, which includes an extensive array of brackets, mechanical parts, and electronics to support innovative builds.
What makes these servos “smart” is their ability to be fully configured by the user. They support feedback on voltage, current, temperature, position, and RPM, and include integrated safety features. Although they perform optimally when connected to a microcontroller or computer, they can also function as advanced RC actuators. Communication and configuration are made easy via the custom LSS serial protocol, which is built on the SSC-32/32U framework, making interaction intuitive and user-friendly.
It is important to note that the servo cannot function independently, as it lacks an onboard communication interface. The recommended accessory for interfacing is the Lynxmotion (LSS) Adapter Board (USB Type-C), which is compatible with USB, Arduino, and Bee socket connections. While other 5V USB-to-serial adapters may be used, separate power (6-12V) must be supplied to the servos. RC systems are also compatible, provided the servos receive adequate external power.
Lynxmotion offers various accessories to enhance servo functionality. The LSS Power Distribution Board (LSS-HUB) simplifies power and communication management by distributing current and splitting the LSS bus between servos, and it can be directly mounted to the servos for streamlined integration. Additionally, custom-designed gears and the SES-V2 Geared Gripper Kit provide further mechanical functionality. The gripper kit features strong aluminum plates with foam padding to grip objects effectively, and inner teeth help secure difficult shapes.
Software support includes the Lynxmotion LSS Configuration Software (LSS-Config), which allows users to view, modify, and update firmware settings on the smart servos. Overall, the Lynxmotion LSS-ST1 is a high-performance, modular servo ideal for a wide range of robotic applications, backed by a robust ecosystem of supporting hardware and software.
