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 systemThrough 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...

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...
