Boat actuation mount design

Grace Kwak

I have begun testing different designs for mounting servos and DC motors in any orientation and at any position on each of the boat hull morphologies, as shown in these photos: servoMountDesigns.pdf. I'm testing them by hand first (using tape and scissors), before sending them off to Jill for her...

Implementation of rudder steering

Grace Kwak

I have built the first prototype of a boat with rudder steering. This video shows the rudder steering in action. We ran the boat four times and obtained these results: When the rudder is straight, the boat goes (relatively) straight. When the rudder is tilted to the left, the boat veers to...

Robotic boat paddle-wheels and propeller

Grace Kwak

After completing the boat's electrical base, I began testing different paper chassis designs for driven propellers and paddlewheels. I used the dashboard joystick to control the motors wirelessly while noting each boat's performance. The paddlewheels use servos driven by the Adafruit Servo FeatherWi...

Hardware testing setup for powered robotic boats

Grace Kwak

I set up the Adafruit Huzzah32 Feather Board with the FS90R continuous rotation servos (powered by an external power bank), the Adafruit NeoPixel FeatherWing, and the Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout. In addition, I got the Roco library working locally on my computer and wil...

LOGiCS Challenge Problem Slides

Pehuen Moure

"LOGiCS is a project funded by the DARPA program on Symbiotic Design of Cyber-Physical Systems. The aim of the project is to develop design tools and techniques that augment human designers with an AI co-designer towards achieving significant improvements in design productivity as well as design 'su...
