So, lately during the summer I wanted to have some new robots for the students to work on. You know, some motors, couple of sensors, built-in Arduino-like electronics, that kinda stuff. And after about a week of searching I found a perfect robot … a 3D printer.
(sarcasm warning) Due to a recent massive surge of interest in the blog and the sheer terror of somebody actually reading it (yes, I’m looking at you Ola and Gosia), here we go with a rather pointless post – a quick autops… I mean, precise dissection of a 3D printer – Tiertime / PP3DP Up Plus 2. Or, at least, a glorified photo shoot.
Goal: postprocess what absolute magnetic angle measurement sensor (woah) AS5048a returns with Matlab in order to see plots and make animations.
First result: what in the name of valhalla is the Matlab serial doing?!
Second result: works.
The adventures with the Crazyflie on Linux Slackware 14.2 begins! … with troubles 🙂
The goal is to get it going with Python, then with Matlab, then with Simulink, then with a mount that will bind it nicely to the ground with 3DOF gimbal.
Let’s start with drivers and Python.
This one is a simple experiment done to test if the Dynamixel motor in an open loop (no internal PID) are fast enough when controlled by Matlab/USB-serial so that a HZD-based method will work.
This is an old one – a simple two-wheeled robot (unicycle) based on microcontroller esp8266 (with internal Wifi, in a stamp-like footprint, cool!), two servos, battery and with Matlab connectivity. How it works? Youtube:
