Hello Folks! This time, I am going to blog about my adventures with wheel encoding. I had a few problems (as usual) but solved it as I always do. The IR sensor I used was from Pololu, and I had to CAD out the encoder mount so that the rear wheels of my RC vehicle could be properly measured for wheel...

For our "off-center spinning mass controller" project, we wanted to control Crazyflie and run several different experiments on our drone. Ubuntu and ROS packages provided us with such platform. So we followed below paper as our guide. Flying Multiple UAVs Using ROS Since our Ubuntu and ROS version...

Below is the diagram of current camera configuration separating camera network from Internet in order to prevent any interference. Data interference is more likely to happen if additional cameras were added and they were on the same network as internet. (camera data can take up large bandwidth) : ...

As we near the end of this summer, Emily and I decided to compile everything we have done so far into one concise document. I made some instructions on how to download the software and upload the code to the car's microcontroller, which can be found in the document. I also included the lesson pl...

This week, we have successfully extracted and defined a list of gestures that are universal to our Furniture object Manipulation API. For this project in particular, we defined and mapped the gesture from 3D Space to 2D Space (mobile touch screen). Using this, we can then let designers determine whi...

Pulse Width Modulation, or PWM for short, is a useful signal used to control servos, electronic speed controllers(ESC) and LED lights. It is an essential arsenal for any roboticist. This blog will be about my adventures with PWM signalling. Along the way, I sprinkle my pro tips. I initially assumed...
