- Lynxmotion (LSS) - mechDOG Quadruped Base Kit
- 12DoF quadruped robot for development & experimentation
- Uses configurable & versatile Lynxmotion Smart Servos
- Frame components are made from durable aluminum & G10 composite
- Designed for adding sensors, Raspberry Pi, Arduino & more
- Assembly, programming & additional parts required
The Lynxmotion (LSS) - mechDOG Quadruped Base Kit was a collaboration between Lynxmotion and Mech-Dickel Robotics to create a four-legged (quadruped / quadrapod) robot “dog” with similar degrees of freedom to a mammal. This medium sized platform is intended to provide users with a smart servo based platform for indoor development and experimentation.

Lynxmotion ST1 modular smart 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, single board computer (SBC) like the Raspberry Pi or even directly with a USB cable.

The internal compartment can be quickly accessed using thumbscrews at the top and bottom. There are mounting points at the top for accessories like RPLidar-A1 360 degree laser scanner. 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.

Incorporating Lynxmotion’s Smart Servo Motors (rather than small 9g RC servos commonly used in small tabletop quadrupeds, or BLDC motors for larger quadrupeds) gives the developer significant control over and feedback from the servos. Possible configurations of each servo include angular range, center position, direction, speed, LED color, operating mode (serial vs. RC) and more. Feedback per servo (in serial mode) includes but is not limited to: absolute angular positioning, voltage, current, speed, temperature, servo status. The servos use a “human readable” communication protocol, making them very easy to use and understand. Arduino, Python and ROS libraries are available for the servos.
The mechDOG Base Kit is intended to allow customers to add their own electronics such as a microcontroller or single board computer. Arduino compatible sample motion code which uses RC input is available which the customer can modify for their needs, though as a quadruped legged development platform, the customer is expected to program the robot to suit their needs and application.
