Last weekend, I manufactured a PE balloon envelope. Here is the manufacture process: The PE balloon after inflated: The total lifting capacity is about 41 g. The total weight of the electronics of the control and sensing part is about 27g:

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...

Webots Environment CAD Based on Thursday's meeting with Daniel, I built the following environment modules: (Note: all modules can be scaled and rotated in Webots.) 1. Base: The base is the ground. Other modules will be laid on top of this base modules. I decide to use this base in case we want...

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...

As we discussed last Thu, there are two things to be done, so that our collaborators can have something to work on: Write a controller to make the paperbot go to a specific target location. Build an environment (manually for now) and apply it to Webots, and then replace it with Scenic late...
