I went throught the main reference [1] in my following project, as well as studied the corresponding area, which is called optimal scheduling in sensor networks.In [1], the main work can be decomposed into 4 steps: Discrete time Riccati equation: With observation and propagation, the localiz...

I have finished making the LED blink manually by opening other tabs/windows in my internet browser. With Wenzhong I tried making SCP actuators. The first two times the thread snapped due to too much weight, but the third time at 50g of dead weight the thread remained intact. We still have not bee...

Week 1: [x] Create a schedule & goals with time frames. [x] Get the LED to blink. Week 2: [x] Establish project idea by Thursday. [x] Start & Finish Pre-lab. (

We were able to make the LED to blink using esp8266 / Arduino We are currently learning Python through Code Academy We wrote our project proposals, but they are still in their early stages (living document) We read over and are reviewing Pooja’s Pre-lab on the fabrication process of SCP actu...

During summer time, our goal is to try to achive a single motor&propeller helicopter on Crazyflie by removing three propellers and motors. Week one and two, we measured the thrust on a single motor of crazyflie by diving the total thrust of four motors by four. We found the thrust is not enough to l...

This week, I finally decided my project for this summer with Prof. Mehta.Based on the framework that we developed for cooperative localization, we further consider how to optimize (or minimize the cost) this process with constrained resource. This paper may be the most related one, and I will f...

This week I worked with Jerry, Likai and Carol to test Crazyflie's thrust force. We used the method from [1] to measure the thrust force created by one motor and one propeller on crazyflie with different PWM signal. From the measurement, we conclude the system needs more than one motor to provide en...

Robot made of paper and supercoiled polymer actuators (SCP). Get the robot to move somehow (walking, rolling, etc.). Use a motor control or phone to control the robot. Program the arms to move to positions 1,2,3 and be able to grab onto different objects (e.g. metal can, glass bottle, paper ball). Read more articles & journals, searching for key words I want to focus on. Delve more into taking weight into consideration & how heavy a load the paper robot can withstand. Investigate ways of folding the paper & what shapes would give it the most strength, durability, & efficiency. Technology for a robot or other such device to recognize trash, recyclebles, & compost does not yet exist, but we can build & design & research for that idea.

Last quarter I continued the study of drone simulations and focused on Crazyflie 2.0. By reading Crazyflie’s Technical Report: Design of a Trajectory Tracking Controller for a Nanoquadcopter [1] and looking into Crazyflie’s source codes[2], I had better understanding of the control algorithms us...

When I first joined this research group I started working with the RoCo team helping them with documentation and improving file formatting. I then started working on a side project: a paper bot powered by a phone that could be designed using RoCo. At the beginning I mainly focused on how to allow co...
