Air Learning, an open-source simulator and gym environment where researchers may train RL algorithms for UAV navigation, was recently built by researchers at Harvard University and Google Research. This one-of-a-kind environment, described in a study published in Springer Link’s Special Issue on Reinforcement Learning for Real Life, has the potential to improve the performance of autonomous UAVs in real-world scenarios Reinforcement learning (RL) algorithms have produced extremely promising results in allowing increased autonomy in robots in recent years. However, most contemporary RL approaches are largely concerned with the architecture of…

Researchers at Nanyang Technological University, Singapore (NTU Singapore)  have created a flexible and stretchy battery that is fueled by human sweat. The prototype battery is made out of printed silver flake electrodes that create energy when wet. The battery, which is 2 cm by 2 cm and is as flat as a little paper bandage, is attached to a flexible and sweat-absorbing cloth that is stretchy and attachable to wearable devices such as watches. The team of scientists tested its gadget with fake human sweat to illustrate its potential application…
