Status
Development.
V2.2 Frame is being tested and is nearly ready for replication
General
Zuko uses the ROS2 framework for communication, launching, and 3rd party addons. Zuko uses a Rasberry Pi 4 with a custom expansion board for motor and peripheral control via a Playstation 4 controller.
Current Major Tasks
Complete ROS2 tasks - in progress
Fab/test expansion-board PCB
Update BOM
Create PCB BOM
Upload STL's
Create print time/weight sheet
Create how to documentation for end user
ROS2 Workspace
ROS2 source code is contained the quad_ws directory.
My contributions
Frame redesign using larger servos, providing more space for electronics, rework of the leg/hip system, and addition of aesthetic features (tail, etc).
Migration of source code from ROS1 to ROS2 (Robot Operating System) frameworks.
Inverse kinematics for a linked leg system for OpenQuadruped / Spot Mini Mini based quadrupeds.
Parameterized duplicated hard-coded values.
Created servo calibration script for quicker calibration and servo support.-
A more feature rich motor and peripheral expansion board using a Teensy 4.0 supporting aux servos, foot sensors, NeoPixls, etc.
8x 18650 user accessable battery holder with onboard BMS (battery management system).
