Electrical Components

Electrical Architecture:

Arduino (controlling DC motors)

Raspberry Pi (controlling camera)

Orbita:

  1. DC Maxon Motor

  3. 1 Controller per Motor with Pi? https://www.raspberrypi.org/forums/viewtopic.php?t=238904 Motors are controlled by Arduino

  4. Pollen uses these components for each motor: Unclear how they relate

    1. Luos DC Motor Board (Connect up to 2 motors) — https://www.generationrobots.com/en/403429-luos-dc-motor-board.html
    2. Pololu magnetic encoder — https://www.pololu.com/category/201/encoders
  5. Motor river: L298N

  2. Camera(s)

(Pollen has these communicating through USB) [picamera modules don't have USB, just the ribbon cable]

https://projects.raspberrypi.org/en/projects/getting-started-with-picamera

Since rPI only has one camera port, the official BOM calls out an Arducam board (form factor = HAT) that can handle multiple camera streams, while sending a single stream via a ribbon cable to the rPI. The newest Arducam boards can handle stereo and 3D. https://www.arducam.com/dual-camera-hat-synchronize-stereo-pi-raspberry/.

[NOTE: Pollen now uses Logitech USB cameras, instead of rPI cameras, so the Arducam board is no longer needed.]
