    Control System Redesign:

    I now plan on making the system fully radio controlled. The new main board will likely be an ArduPilot APM. And the video stream will be a 900MHz POV camera.

    Chassis Redesign:

    The chassis will be made of ribs that run parallel to the wheels and bars that run perpendicular to support the ribs. I have a prototype paper design for the kicking mechanism. And I have some ideas for suspension.

    I will post some designs when I have more CAD models.

  • Wheel servos working

    Progress:

    The main drive system use MG-996R continuous rotation servos controlled by a Raspberry Pi 3B with a servo hat. I rewrote the servo hat python code (Adafruit Servo Pi Hat) into C  to allow for better integration with my code in the future (See file).

    Upcoming:

    3D printing of wheels and chassis to allow for 'RC' via ssh. The wheels will be at most 8" diameter and printed out of PLA, because my printer still requires tuning before switching to other filaments. In the future I plan on using Nylon 910 or similar filament for wheels. And chassis will likely have some metal in its frame.

    Next Steps:

    Design decisions on whether the drone will be controlled via RF or via WIFI. And how to stream video to control system (drone POV vs webcam). As well as integrating my preliminary jumping mechanism into the chassis design.
