Update: I found a typo in the modeling I presented last week. I has been revised. The new model makes sense by looking at the trends. The model is validated at some extreme situations (e.g. then crease folding angle alpha=180deg). Out-of-plane bending is added to the analysis. So now we ha...

Markdown beginner's guide I'm exploring this Markdown recently and I found it really simple and elegent. So I would really like to share some of what I learnt with everyone. I'll keep it up to date in the future. You can also download Markdown beginner's guide.md file from my git Content W...

Foray Blimp Becoming Mobile Big Picture In order to build the optimal blimp for competition, we are currently focusing on modeling the different parts of the blimp’s movement. Specifically, movement in the horizontal plane and altitude control. In terms of horizontal plane movement, we are seekin...

A cubic spline is a spline constructed of piecewise third-order polynomials which pass through a set of n control points. According to [1], a cubic spline \(S(x)\) can be defined as: \(S(x)\) is a cubic polynomial \(S_j(x)\) on [\(x_j,x_{j+1}\)], for all \(j = 0,1,...,n-1\). \(S_j(x) = a...

For the last week, I worked on paper revision and response letter for the Robotica paper about the integrated design and fabrication strategy for electromechanical systems for robotic systems. Inspired by the reviewer's comments, we created a new connection method to construct inclined out-of-plane...

Using the analytical model developed last week, with certain geometry constraints, stiffness of the proposed orthogonally assembled double-layer corrugated structures have been evaluated. Using design parameters optimized from maximum stiffness requirements, a rectangular shape sample and a circular...

Objective: Detect gesture as tuning gesture Find discrete parameter of selected object Use gesture to tune the parameter and update the object Implementation Steps Detect hand gesture as tuning gesture (in our current example, we are using thumb-up gesture, it can be customized, and the o...

Weekly Update - As part of the FORAY team, I worked on building a mathematical model of the blimp on Simulink. I familiarized myself with dynamic equations of the motion of the blimp. Modeling - Tutorial I used to learn the fundamentals of Simulink – http://ctms.engin.umich.edu/CTMS/index.php?e...

This summer I am working with other members of LEMUR on the FORAY project where we are developing a fleet of LTAVs (lighter-than-air vehicles) with a design emphasis on speed and agility that can compete in a game of aerial soccer or Quidditch. Below is the overal structure of the different aspect...

Objective: Detect hand gesture as rescaling gesture (need both hands) The scale of selected object changes along with the distance between two palms Implementation Steps Detect hand gesture as rescaling gesture (in our example, defined as palm-to-palm gesture, which can be customized and th...
