Finally, our work of the mechanical logic was presented in the ISER, Nov. 2018. In this paper, we introduced the mechanism of the mechanical logic and demonstrated its ability to induce electrical current oscillation with a constant-current energy source. For more details, you can refer to our paper...

During the past week, I have been reexamining the linearization script I created for the attitude controller. The difference between results from my implementation and literature values might be attributed to 2 sources. The assumption that the propeller speed in the body frame relative to earth...

As I mentioned in the group meeting last Thursday, to better communicate what I have been doing with the modeling of one subsystem of the mechanical logic, I am writing up and summarizing my progress up until now. I included some pics from my writeup, but the full pdf will soon be on my personal pag...

I have implemented linearization and LQR controller in the attitude control block. Previously, I tried to test the correctness of the dynamics block by trying to maintain hover after initializing the flyer at a hover posture. However, the flyer is only able to maintain the position for 06 seconds. B...

For the past week, I was woking on the writing the introduction for the upcoming RSS conference. In this paper, we will introdce our work on the modeling of our mechanical logic. This model uses a quasi-static electromechanical scheme to simulate the dynamic behaviors of our mechanical logic, which...

This summer, I, along with Phipson, did a "design for everyone" project, which is to say, we built a system called FAVECAD (Fabrication in Angumented and Virtual Environments for Computer-aided Design) to help everyone (including non-designers) to design. This system combines advantage of AR and...

So far, the Mechanical Logic team has completed their first paper and submitted it to ISER2018 (2018 International Symposium on Experimental Robotics). Thanks for the hard work of Dr. Mehta, Angela and Blaire. The team is able to induce current oscillation through the combination of Bistability...

Hello Folks! This time, I am going to blog about my adventures with wheel encoding. I had a few problems (as usual) but solved it as I always do. The IR sensor I used was from Pololu, and I had to CAD out the encoder mount so that the rear wheels of my RC vehicle could be properly measured for wheel...

For our "off-center spinning mass controller" project, we wanted to control Crazyflie and run several different experiments on our drone. Ubuntu and ROS packages provided us with such platform. So we followed below paper as our guide. Flying Multiple UAVs Using ROS Since our Ubuntu and ROS version...
