The Lynxmotion (LSS) - 4 DoF Robotic Arm (kit) is Lynxmotion’s 6th generation articulated robotic arm. This unassembled version is intended as a hobby / scale version of an industrial robotic arm and is designed around the fully configurable Lynxmotion Smart Servo motors and Lynxmotion Servo Erector Set (SES v2) modular construction system.

Given that the structure of the arm is comprised of modular brackets and servos, purpose-built and ultralight aesthetic plastic shells give a futuristic look to the arm without impeding any motion. The shells are held in place using neodymium magnets, and vinyl stickers allow for personnalisation.

This versatile setup facilitates customization and expansion for applications through the use of additional brackets, electronics, sensors and more, and adding additional degrees of freedom or changing the gripper is straightforward.

LSS Articulated Arm with and without shells

Although well suited for use on a desk for development and experimentation, the arm can be easily fitted on a mobile robot and powered using a 3S (11.1V) LiPo battery (sold separately) with XT60 connector. The included LSS Adapter electronics board makes connecting to an Arduino shield compatible board, Raspberry Pi, XBee or other serial device easy.

CAD design files, as well as examples using Arduino and Python are available so that students and hobbyists can integrate the arm into their projects. The graphical user interface, LSS FlowArm (created using FlowBotics Studio) makes recording and playing back sequences effortless.

The Lynxmotion Smart Servo motors were designed and optimized for articulated robotic joints and ease of use. The custom LSS communication protocol is human readable, uses full duplex (dedicated Tx and Rx lines) and selectable baud rates. Optimize the motion by changing the properties of each servo; anything from setting a maximum speed or angular range to the angular acceleration, holding stiffness and more. Each servo can be queried for a wide variety of real-time values or configured settings, including sensor feedback from the absolute encoder (position, speed and more), current, voltage and temperature.
