I have spent the past weeks assembling a blimp on which to test a feedback control system to aid in controlling the blimp as well as building said control system. The picture below shows the experimental setup. So far, the blimp is assembled and controlled based on IMU motion. The video below...

How to customize batteries according to your requirements? It is very challenging to design a battery to satisfy specific loading. For example, you may need to have a battery that can outup certain current when connected to an electric-driven actuator with a certain resistance. Similarly, for our pr...

It took me a while to really understand the structure of the okvis SLAM system. In order to prevent from studying its structure all over again, it is better for me to put down what I understand so far. The main goal of this post is to bridge the gap between the theoretical understanding and the so...

I have added time remaining functionality to the power consumption board that I have. However, it is not refined and therefore has a few caveats for use. The program assumes that the battery is at full charge upon program start. While there is no current through the sensor, the time remaining wi...
