At the same time I worked on modeling the critical force and critical displacement of the bistable beam, I also looked into the way these behavioral parameters affected the final output parameter of the system--the oscillation period of the mechanical logic. I integrated the models for the mechanica...

Due to the shortcomings of the ROM (it's really hard to translate into our fast, model-based design method for the mechanical logic), I have started to work with a new model that we used for the ISER paper (it turned out more than a piecewise linear model that came to the rescue at that time). This...

Last week, we reviewed the current state setup of the linearization script. Since the derivative of the total thrust cannot be calculated from the definition of the derivative, the total thrust should not be in the state. The error comes from misunderstanding of one of the equatoins of the original...

Once I constructed the the mesh of our track in Meshlab I needed to import the mesh into unity. Unfortunately Unity does not read per vertex colors so I a made a texture from the mesh so that it could be applied to the colorless mesh I imported to unity. However the texture I created using the per t...

This week was mostly focused on writing a prelab report and setting up the experiment for the data collection.Prelab : A prelab report for the experiment was written so that all the project team members and I could prepare for the professional RC driver to stop by and collect data. Optitrack Mo...

This is part 2 of the slam algorithm overview focused on Particle Filter related SLAM algorithms. It is aimed to provide readers some basic understandings on different SLAM algorithms and their relationships.

One of the things I'm working on right now is setting up the environment of our unity simulation. This simulation will need to be a realistic representation of the track we are using. In order to achieve this we use an intel realsense camera to scan the track and generate a 3D point cloud. However U...

For the past few weeks I have been looking at the EKF-SLAM inconsistency problem. I've compiled what I've found so far into a short literature review linked here . This includes some references for proposed modifications to the EKF-SLAM algorithm. Based on what I've looked at so far, the ways to r...

The PyBlueZ library provides an easy to use interface for communicating over Bluetooth in Python. While Python has native support for Bluetooth with its sockets interface, it is only available for Python v3.3 and up. In addition the PyBlueZ provides a lower-level interface for Bluetooth that can b...

Currently, I am studying Lie group to understand the application on localization. Here are some materials that I found very useful:B. C. Hall, ``Lie groups, Lie algebras, and representations : an elementary introduction,'' 2015. youtube lectures from Dr. Fredric Schuller The first book can be...
