    Small-scale autonomous boat made out of recycled water bottles and a Tupperware container

    Arduino Team — December 16th, 2021

    As part of their city’s beach restoration project, Instructables users Kousheek Chalraborty and Satya Schiavvina, who go by the team name Technovation, needed to construct a small and cheap boat that could assist in mapping the depth of the sea floor at various locations. The design they were able to come up with achieved this goal and even went beyond it by incorporating an autonomous navigation system into their watercraft. 

    The hull of the boat was made from a leftover Tupperware container and discarded water bottles, therefore reducing the cost significantly and integrating recycled materials. After the pontoons were attached to the bottom, a pair of brushless DC motors were screwed into place at the top, along with an 11.1v LiPo battery and dual 30-amp ESC modules.

    At the core of the robot is a single Arduino Uno that has a custom shield mounted to its top pin headers. This board consists of an nRF24L01 transceiver module for sending/receiving telemetry, a GPS module for tracking position, and a compass module that determines the boat’s orientation. With the firmware loaded onto the Uno, Kousheek and Satya created their own dashboard in Python that allows them to view information in real-time as well as send commands from across the water.

  • Opa is an open source boat bot that navigates the open water

    Arduino Team — November 16th, 2021

    Starting with an idea in 2019, Redditor wesgood has been steadily working on the Opa — an autonomous 3D-printed boat that can navigate open water while relaying its telemetry back in real-time to a client device over WiFi. After creating a small prototype, Wes built a second one that featured a pair of pontoons held together with a couple of struts and a central platform. This design contains a single water jet that is situated in the back of each pontoon that takes in water and shoots it out at a high velocity, similar to a jet ski. Best of all, they can be independently throttled which eliminates the need for a rudder. 

    As far as circuitry goes, the Opa houses an Arduino Mega that has a custom shield on the top for controlling the pump motors and reading data from the onboard 9-DOF IMU and battery voltage/current sensors. An auxiliary Raspberry Pi runs Ubuntu Server, and its job is to coordinate data coming from a GPS receiver and information from the Arduino Mega with a wireless client device. 

    After getting the necessary software loaded onto the Arduino and Raspberry Pi, Wes placed them inside of a watertight enclosure on the top of the boat. His mobile app could then be used to see relevant telemetry, power consumption, and the current location of the raft overlaid on a map. Additionally, the user has the option to manually pilot the boat if they so desire as well.
