For the past week, Blaire and I were working on the paper writing for the analytical modeling of bistable buckled beams with off-center actuation. We worked together to clean up the derivation of our models and finalize Section "Resultes and Disccusion". So far we finished most of the work except...

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...

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...

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...

Angela and I have been working on testing the strain of SCP actuator this week. We designed a testing system to allow rapid prototyping for our mechanical loigic. By attaching the actuator on the bistable beam, the strain of the actuator can be measured with small or without preloaded tension. And t...

Last few days, we tried to use a 'new' thread to fabricate our SCP actuator. The most difficult part is that the mechanical propoties are so different from the previous thread though they have the same product number and came from the same retail. We ran a lot of tests to reset the coiling and annea...

For last week, I created flexible joint for furniture design to expand the design space. This flexible joint can allow two faces join togrther with certain angle while the finger joint only works well for 90 degree. But currently, our system has limited choices for one furniture design, which means...

For the last two weeks, I summarized the work of Mechanical logic and finished the draft of paper for upcoming ISER. The model for mechanical logic is needed and is the main focus for the following several weeks. I will build a model to help to predict the behavior of mechanical logic and guide the...

This week, the function for adding finger joint was improved. Now we can add joint to any edges that have the same length. When the dimention of edge is suitable to add finger joint with the selected material thickness, the finger joint will be added. Otherwise, we will automatically add glue joint...

This week, I spent most of time on reading reference to find the way to decrease the thredshold to actuate the bistable beam. As far as I know, there are several ways to achieve it. One of them is to move the actuation spot close to midpoint of bistable beam. And I modified my design according to th...
