11 +Lynxmotion’s three degree of freedom (3DoF) articulated robotic arm was designed around Lynxmotion's configurable smart servo motors and is intended to be inexpensive yet highly versatile. 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.
12 +
13 +{Slow GIF showing arm moving with gripper remaining parallel}
14 +
15 +The included Mini Parallel Gripper uses a micro RC 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.
16 +
17 +{Pictures of gripper closeup mounted on arm in each configuration}
18 +
19 +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 and LSS-5VR voltage regulator mean the normal RC servo in the gripper can be used with the LSS communication protocol. 
20 +
21 +{Closeup photo of 5VR and 2IO on arm}
22 +
23 +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.
24 +
25 +Combined with the Lynxmotion conveyor system, a tabletop assembly system can be created within a few hours. Although well suited for use on a desk for development and experimentation, the arm can be easily fitted to a mobile robot and powered using a 3S LiPo battery (sold separately) with XT60 connector.
