Over the past week, I have been looking into what are the best tools/ways to create a mesh network for our ESP32 boards that will be attached to the blimps. The three frequencies we want to add to diversify are 2.4 GHz, 433 MHz radio, and mmWave 20 GHz. For the 2.4 GHz option, ESP-now looked like...

Dash I worked with the team of undergrads to develop this initial list of requirements for the dashboard. It's based on the kinds of experiments we plan to run and what kinds of data will be relevant. Of course, this is a preliminary list only, but I've specified that we will use modular design so...

Current progress: In the past week, I tested the opti-track system streaming function. Before, after I used opti-track to capture the motion of our flying blimps, I had to manually import the data to a csv file and then process the csv file. This whole process took a very long time since in the...

Following up with Alexie's post last week, we furthermore show that the simulation of BOEM SLAM algorithm for 1000 sec. The result is the average of 5 trials. The computation times for other algorithm, including optimization based and the EM SLAM, are too large for 1000 sec, but we have the comparis...
