Introduction: Pi0Boat: a $250 Smart Aquatic Vehicle With the Pi Zero

A Linux-based smart aquatic vehicle.

Step 1: PROJECT INFO

Difficulty: Intermediate

Estimated time: 12 hours

Erle-Boat

Erle-Boat is a Linux-based smart aquatic vehicle that uses robotic frameworks such as ROS (the Robot Operating System) and the award winning APM software autopilot to achieve different navigation modes.
Erle-Boat is ideal for water operations.

Mechanical features

  • Dimensions: 520 * 330 mm
  • Weight: 770 grams fully assembled (battery included)

THINGS USED IN THIS PROJECT

Hardware components:

Erle Robotics PXFmini x1

Raspberry Pi Zero/W x1


Suggested parts:

  • PXFmini with WiFi 802.11ac USB dongle, microUSB to USB adapter for WiFi, Flashed MicroSD, Power module (JST GH) and GPS (For PXFmini) [Optional / Improvement]
  • Raspberry Pi Zero
  • HobbyKing Pod Racer Boat 520mm
  • Radio controller
  • Battery

Step 2: Assembly

PXFmini Configuration

The PXFmini should be configured. Request the latest image for your PXFmini or acquire a flashed one with your order to Erle-Robotics.


Having the PXFmini you need to:

  • Set as a Erle-Rover

The easy method is via HDMI with the Erle-Robotics User Interface

  • Connect via network to APM

Connect via network to APM and Load Parameters for Erle-Boat

Step 3: PWM Inputs

The ESC should be connect to the motor and to the PXFmini's PWM #3. The Servo, need to be connected to the PWM #1

Everything in place
Ensure everything is in place. Check that the motor and servo can move free.

Step 4: Test

Be careful with the propeller. A suggestion is to make the first test with the Erle-Boat in a controlled area.

What kind of run time do you get with the battery?

Depends on the motor and the use of the boat. We were just having fun and testing it, run it about 10-15 minutes and we didn't drain the battery.
