  • Lynxmotion SES-V2 High Torque Smart Servo (LSS-HT1)
  • Features a configurable, modular smart servo motor
  • Designed for the Lynxmotion Servo Erector Set (SES)
  • Offers 60 RPM - no load (12 V)
  • Includes metal gears, RGB LED bar, and sensor feedback
  • Provides smart / wheel / RC modes
  • Now with Full Aluminum Body (NEW)

The Lynxmotion SES-V2 High Torque Smart Servo (LSS-HT1) are new compact, modular actuators which were designed to be an evolution of the standard RC servo for use in multi-degree-of-freedom robots, animatronics, custom RC projects and more. The lineup currently includes three “smart servos” which differ in maximum torque and speed, and share the same dimensions, mounting points, and output spline.

The servos form the core modules of the next generation Lynxmotion Servo Erector Set (S.E.S.) and a wide variety of modular brackets, mechanics and electronics have been designed around them. "Smart" means each servos' parameters are user-modifiable and configurable, there is sensor feedback (Voltage, Current, Temperature, Position, and RPM), built-in safety features, and although they work best when connected to a microcontroller or computer, can be used as advanced RC actuators.

The custom LSS serial protocol was built upon the SSC-32 / 32U protocol and makes communicating with and configuring the servos one of the easiest and most intuitive to use.

Note: The servo cannot be used on its own as no communication interface is included with the servo. The suggested serial interface is the Lynxmotion (LSS) - Adapter Board (USB Type-C)(USB, Arduino, Bee socket compatible), though most 5 V USB to serial adapters can be used (be sure to provide power separately). Any RC system can be used, though 6-12 V power to the LSS servo(s) should be provided separately.

Lynxmotion (LSS) - Adapter Board (USB Type-C)

The Lynxmotion (LSS) - Adapter Board (USB Type-C) is an electronic board that allows for easy connection to and control of the Lynxmotion Smart Servos. The board includes a variety of features and functions as a central power distribution board via six LSS connectors.

The Lynxmotion SES-V2 Power Distribution Board for LSS (LSS-HUB) provides a simple solution to supply power to and communicate with the smart servos. It is also a useful tool to split the LSS bus from one servo to two or three while allowing these servos to be powered separately. The Power Hub can be mounted directly to the servos.

Lynxmotion SES-V2 Geared Gripper Kit

The Lynxmotion SES-V2 Geared Gripper Kit is made of durable aluminum plates and standoffs and uses foam to conform to the object being grasped. Inner teeth on the aluminum help "bite" into objects when necessary.

Works as expected

Works well and delivery was smooth and quick.

You get what you pay for

These servos are slightly expensive for a novice user however having played with them they are well worth that extra cost. With that said they pack a punch and are cheaper than competitive servos with similar ratings. The money you pay for these is very noticeable and I can't wait to get more of these in the future. Not only for their performance but also how well made they are. I haven't yet Not found a way to mount these as the mounting pattern is brilliant.

Fun to buy something that works.

I knew almost immediately this product wasn't the usual cheap junk from China: The secret: It did exactly what robotshop said it would do(*). It's a little surprisingly, actually, it can move a 6Kg weight with a horizontal 1cm lever without overheating and melting. Also, the instruction set is super simple. (*) I've lost track of how many times offshore vendors massively exaggerated specs, resulting in tears, fires, and a pile of broken junk
