Lynxmotion's mechDOG was created as a collaboration with Mech-Dickel Robotics (YouTube Channel) to create a four-legged (quadruped / quadrapod) robot with similar degrees of freedom to a mammal. ST1 modular servos are used throughout, along with a variety of Lynxmotion Servo Erector Set (SES) V2 brackets. The body plates are made of composite G10 and the body side panels are anodized aluminum. The LSS Adapter acts to split battery power to each leg, and can be used with either an Arduino shield-compatible microcontroller or single board computer (SBC) like the Raspberry Pi. The internal compartment can be quickly accessed using thumbscrews at the top. There are mounting points at the top for accessories like YDLidar's 360 degree laser scanner or other SES V2 brackets. The size of the robot and built-in functionality of the smart servos make it ideally suited as an inexpensive development platform onto which a variety of sensors can be mounted and used for autonomous behaviors, navigation and more.
