Mojo - Robot Dog

Mojo is a Compliant Quadruped Walking Robot Dog.


Mojo2 - Oct 30th 2018
Mojo - the name of my pet Dog
Compliant - the springs in the leg provide 'mechanical compliancy', storing and adding energy to the walking gait
Quadruped - Four (4) legs
Walking - It moves with a gait or walking motion - no wheels here
Robot - Mechatronics at its best, a microcontroller 'brain' and servos to convert the digital to the physical
Dog - or other representative small quadruped - Jack Russell Terrier to be exact! ;)



For the complete history and Introduction to Mojo read through the topic posts for the Label "Mojo".  Mojo was inspired by the robotic work done at the ETH Zurich Robotics Lab,  researching biomimicry of animal gaits in robotics.

Mojo is completely designed, 3D printed, and built as part of my Totally Not Evil Robot Army.  Design work was created in OpenSCAD and printed on a Creality CR10 3D printer. Mojo is controlled by own built software running on a Arduino mini pro microcontroller. It uses an XXXX servo 16 channel servo driver board to control 8 servos. Batteries are provided for servo power and microcontroller operation. Special Serial  Elastic Actuators (SEA) were designed and built using 3D printed parts and parts from recycled printers.  The knee cam and hip servo control is directly inspired by ETH Zurich design - but uniquely designed and built independently by myself.
