Maker Boat Basic Shake Down on a Windy, Wavy Day

Build/Make
1

Hi there everybody- I want to post my progress with the Maker Boat Basic. It’s designed as a modular system that can turn just about any (small) thing that floats (think- surfboard, SUP, kayak, etc.) into an autonomous surface vehicle.

I am using 2 Blue Robotics T200 thrusters and mounting brackets with basic ESCs, a Pixhawk 2.4.8 + GPS and Sik Radios, FrSky x9 lite and x8r for TX/RX, all powered by a single 4S 5000 mAh Lipo. All the electronics are housed in an IP68 junction box with IP68 cable glands for the motor cables. In this first build I have mounted everything to an old body board that a buddy was going to throw out. I 3D printed mounts for the junction box, two small fins to protect the motors, and of course a plate for my GoPro up on the “bow.”

It’s running ArduRover skid steer. Configured/monitored through QGC.

This is an open source build. Docs and BOM will be posted soon. I plan to upgrade to dual batteries in an external battery box so the batteries can be hot-swapped without exposing the rest of the electronics to the elements.

Any feedback is welcome. Check out the pic and video here: Maker Boat Basic Shake Down on the River - YouTube

Hey @nuballawalla, thanks for sharing! I love the versatility of the system. Do you have any specific applications you’re planning on using it for? :grin:

This is a wicked cool project! What kind of micro controller are you using?

Hi,

very simple and strong design.

Before I can say something, I would like to know what kind of application are you looking for:

  • Bathymetries
  • Sidescan
  • Flowmeter.

I have built something similar, see Batimetria Embalse Paso Ancho Enero 2020 - YouTube

I really recommend to include fins and keels on the stern, so will help you with steering control.
If you are planning a survey grade, need to have a nice GPS (RTK or PPK)

regards
Luis Chavez

Hi @emiller! Thanks for your interest, and apologies for the delay. The Maker Boat Basic was conceived to make autonomous boats available to educators/students, researchers, and those who want an affordable and reliable platform, but without the military contractor price tag. The boogie board offers a fair amount of space and flotation so it can be customized pretty easily for shallow bathymetric surveys, surface water surveys (perhaps by mounting an open CTD, or just plain fun!

Hi @Slarskey! Thanks for the kind words. I am using a Radiolink Pixhawk. I will upgrade that in the future

Hi @luis.chavez! Thanks- your build looks very similar. Great minds! I printed some basic fins and they work well. I don’t have a specific application in mind, and that’s deliberate. I wanted to create something that others could customize easily. I have used the emlid reach and Navio2 on a quadcopter before, and I thought of using that in version 2.0
