This is a Robotic Dog inspired by Boston Dynamic's Spotmini, but this time on a much smaller scale. This version of the robotic dog is created with a dozen Servos and some other components such as an Ardurino Nano.
You can find a great instructable covering how to create your own Servo Tester here:
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Arrangement of Servos & Kinematics
It is best if the Servos are arranged at 90° and then mounted on the "legs".
All Legs = 48mm
Shoulder to Shoulder Pivot = 40mm (Left to Right)
Shoulder to Shoulder Pivot = 80mm (Front to Back)
With 90° being centered and perpendicular when assembled:
Shoulder Pivot +/-17.5° (Left/Right)
Shoulder Pivot +40.0°/-46.5° (Front/Back)
Knee Pivot: +70°/-73° (Front/Back)
Step 2: BOM & STL Files
(1) Arduino Nano (Headless)
(1) 16ch PWM driver
(12) Tower Hobby 9g servo
(2) Frame-Vertical Pivot
(6) Frame-Stiffener Vertical
(6) Frame-Stiffener Horizontal
(4) Shoulder Pivot
(2) Leg-Upper LH
(2) Leg-Upper RH
(2) Driver Support
(1) Nano Support
The Stls can be found here:
Full Credits to Design Cells for releasing the Stl files on Thingiverse; I didn't Design this myself.
Step 3: Done!!!
The code has yet to be released yet, but I'm sure that it'll be released soon. If anybody knows how to code, please relate to the original author.
