The Lynxmotion SES-V2 Robotic Arm (3 DoF) w/ Smart Servos Kit was designed to be an inexpensive yet highly versatile robotic arm using the fully configurable Lynxmotion Smart Servo (LSS) actuators. The four-bar mechanical design ensures the end effector remains parallel to the surface, and offloads much of the weight of the joints onto the base. Combined with the Lynxmotion conveyor system, a tabletop assembly system can be created within a few hours.

LSS 3 DoF Arm with Conveyor

Although well suited for use on a desk for development and experimentation, the arm is meant to be easily fitted to a mobile robot and powered using a 3S LiPo battery (sold separately) with XT60 connector.

The included Mini Parallel Gripper uses a micro servo, acrylic and foam to be as lightweight as possible. The gripper opens to 40mm and the bracket allows it to be mounted horizontally or vertically.

LSS 3 DoF Arm Gripper Options

The arm includes three main electronic components: The LSS Adapter makes connecting to a computer, Arduino, Raspberry Pi, XBee or other serial device easy, while the LSS-2IO programmable microcontroller (which control the gripper RC servo) and LSS-5VR voltage regulator mean the normal RC servo in the gripper can be used with the LSS communication protocol.

LSS 3 DoF Arm 2IO & 5VR Modules

CAD design files, as well as examples of how to communicate with the smart servos via Arduino and Python are available so that students and hobbyists can more easily integrate the arm into their projects. The graphical user interface LSS FlowArm, created using FlowBotics Studio, makes recording and playing back sequences effortless.
