This week Wenzhong and I successuffully completed our stage in testing our actuator in the testing system. We began to experiment with our actuator using our mechanical logic created out of polyester sheets. The bistable beam beam in the center is able to snap through on a single side. Next week we...

Crazyflie motion analysis with Optitrack system Through past week we set up the motion capture system in the lab using 6 cameras positioned in the orientation shown above. Then we did camera calibration and and ground plane refinement using CW-500 and CS-200. In order to detect Crazyflie u...

Here is the cubic force-displacement curve obtained after I adjusted the parameters / coefficients based on the results from our experiment.

Heyo I'm Derek. Who I Am I joined the lab at the beginning of the summer as part of the SUSP (Summer Undergraduate Scholars Program), which is basically an REU. I will be working with Amir Omidfar on designing a controller that uses an off center mass to control a rocket. I inherited this projec...

This past week, through multiple attempts of manipulating and exploring the utilities and interactions between ARCore, used to track Augmented Reality environments; ManoMotion, used to track gestures and hand motion in 3D space using the RGB Camera; and a pseudo-version of the Google Cardboard SDK t...

Last week, I found a video online about a course in which students made an origami animals zoo. Inspired by the first robot in the video, the snailbot, I made my own 2D outlines of it using Silhoutte Studio. The red lines indicate where you would cut the outline, the blue dotted lines indicate...

This week I worked on attaching the SCP actuator onto the testing system. To do so, four strings of SCP acututors are created from threads of length of about 35 cm, which is significantly longer than the threads we used before. In doing so, we hope that the stretch of SCP actuator would increase. Ho...

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...

Grid patterns provide a universal and context-independent presentation of space, which can be further incorporated with the place characteritic for autonomous SLAM. To reach the final goal, we have to know how the position is encoded in the grid cells first. As a periodic structure, we can use von...

This week I'm working on developing a dynamic webpages. Since the initial purpose is to design a UI which can be applied to multiple conditions. That is to say once a input changes, the interface will display in a corresponding way. To realize this dynamic function, my step is: Apply an interfa...
