Assorted projects and pontifications.
My latest creation is an internet-of-things door lock. The package actuators the deadbolt using a servo and determines if the door is shut or not using a reed switch. There is also a motion sensor that can determine if someone is approaching the door. The lock builds on the SmartThings platform using their Arduino Shield. With it I can control the lock over the Internet using the SmartThings app. What…
After a few sleepless nights, I have finally milled out the pieces for my Mecanum-wheeled robot body. The outer and bottom body pieces are made out of 1/8″ G10/FR4 Garolite. The top two layers are made from transparent polycarbonite. A thin layer of transparent silicon will be placed on the top-most layer of polycarbonite to provide some friction when transporting objects on the top. All of the pieces are held…
I’ve started a new robot project! This will be one of the most challenges personal projects I’ve embarked on. I have the following goals: designed to be a flexible software test platform mechanical design from scratch in SolidWorks, manufactured from G10 low level control through off-the-shelve electronics including an Arduino, SparkFun Quadstepper motor controller, ITG-3200 Gyro, and BMA180 Accelerometer high-level control through mini-ITX computer onboard running ROS 2D SLAM w/…
I recently decided to update my quadrotor’s frame. This frame was designed in SolidWorks and cut from 1/16 inch G10. It has considerations for a GoPro camera, a downward facing ultrasonic sensor, ArduPilot Mega and Arduino (ArduCopter) boards, and much more. I’m pretty happy about how it came out. Let me know what you think in the comments! Update: This frame was not able to fly. Turns out the motor…
This year USC is hosting the National Academy of Engineering’s Grand Challenges Summit. One of my advisors at school has been putting in a lot of work for the summit, so I decided to make him this cool little display. It is battery powered and controlled by an Arduino mini. What do you think?
