robotics/854_bfbc7fe81559e716_651.txt | In order to limit the need for our robot to turn in order to pick up pixels and deposit them on the backdrop, we implemented a basic transfer system into our Ri2D. The primary mechanism that deposits the pixel is an arm with a pixel holder built out of tape and polycarbonate, which we call the “Scoopagon”(it scoops the... |
robotics/572e9ad1_10966.txt | If we have a perfect model and we knew the initial condition of our system, then we would be able to predict how the system state will change over time, perfectly. I mean, why mess around with sensors if we know everything? Well, unfortunately, our ability to predict the outcome of something isn't perfect, it's subject... |
robotics/8895_80ceca0747858829_231.txt | Harmful algal blooms (HABs) are a significant global environmental issue, impacting marine ecosystems, economies, and human health by depleting oxygen in water bodies and causing biodiversity loss. The economic cost of HABs is estimated at approximately $82 million annually, along with posing health risks through toxin... |
