For the past 4 years, SD Robotics 101 has iteratively improved on its cube-shaped design, adding features with each iteration of Cubeception.
Cubeception 3 is designed with modularity in mind, featuring the replacement of the outer frame with pylons and improved thrusters, a two-chambered hull for easier access to the batteries, a raspberry pi cluster for parallel computing, and the addition of sonar and computer vision capability for better navigation. Cubeception 3 is still a work in progress, so stay tuned for updates!
Cubeception 2 features significantly better waterproofing, higher processing power, a removable electronics core, foolproof wiring, and easier maintainance over its predecessor. A heavy emphasis was placed on affordability with Cubeception 2, so several parts such as the connectors, pressure sensor mount, and thruster focusers were 3D printed.
* Innovation on a Budget Award
Cubeception 1 featured a unique 9 inch cube-shaped core surrounded by a 2 foot cube-shaped PVC frame with 24 bilge pumps mounted on it. The main core also contained portholes for a forward Raspberry Pi camera as well as a downward webcam. The bilge pump mounts, experimental torpedoes, and thruster extensions were 3D printed, providing affordable optimizations.
