STL file of the chair was imported into unity3D as seen in the scene. The chair could be transformed in three dimensions through three methods: dragging the spheres in the corner of the box model of the chair, moving sliders and inputting numbers. Translating, rotation and rescaling are also accomp...

Here in below video we put the precision of Optitrack motion capture system to the test. After calibration the system claimed to have only around 0.4 mm of error and as shown in the video we tried to verify this claim. Optitrack data acquisition precision

Last we Wenzhong and I successfully recorded 4 complete oscillations on the mechanical logic. This successfully concludes our goal to create a working mechanical analog of a oscillating system. 1080p 2.mov

This week was a pivotal week for the development of the AR/VR Environment, as both June and I have completed our respective projects and we have started to research into the Unity Multiplayer Networking methods to essentially combine both of these two components together. One of the reasons for usin...

This week we realized in order to send position data from Motion capture system to Crazyflie ROS (Robotic Operation system) is needed. We spent couple days installing Ubuntu and ROS required packages both for Crazyflie and Optitrack Motion capture system. We are also working on motion capture syst...

After finding various robot designs, we looked for lessons that we could potentially make using them. I looked through the Common Core State Standard for Mathematics for the topics covered from grades 5-8 and tried finding related activities to integrate our robots in. Some useful resources I...

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...
