Just Keep Swimming
Created on 20 Nov 2016
A Mobility-Enhancing Fish Tank
This project will allow our pet goldfish Walter to explore the world by swimming around his tank. We will build a driving base for the tank controlled by a Raspberry Pi. Images from a webcam mounted above the tank will be processed by the Raspberry Pi and direct the driving direction. To allow for full mobility, the tank will be completely battery powered.
