#### Identifying weak points and failure modes in foldable structures, different methods exploration

Method of Weighted Residuals + Galerkin Method "Reduce the continuous-system mathematical model to a discrete idealization." "In applied mathematics, methods of mean weighted residuals (MWR) are methods for solving differential equations. The solutions of these differential equations are assumed...

#### How to deal with obstacles in Trajectory Optimization?

In this tutorial, I show how to deal with obstacles in TO. Let's consider a robot moving in a 2D space. The robot needs to avoid rectangle obstacles. Here, I assume that the shape of the obstacles is represented by its lower left and upper right points, $$\left(x_{\min }, y_{\min }\right)$$ and \...

#### FORAY - multiple peripheral devices connected to the same laptop

In case, we have a limited number of laptops to connect the game controllers and master devices. This experiment shows that multiple game controllers can be connected to the same laptop for communication. The current communication system is limited by the number of ports. We can overcome this limita...

#### Next project, identifying weak points in foldable structures

For the last project, we developed a design tool to computational design stiffness-enhanced mechanisms, based on corrugation structures. That project leaves us a question: where should we use stiffness-enhanced mechanisms in foldable structures. Therefore, my next project will be dedicated to i...
