If you’re still on the fence about trying to build your own drawing robot/plotterbot, take heart. (Skip to the bottom of the post if you want to check out the latest 3D printable files and Arduino code.) If a relative newbie such as myself can make a go of it, I’m pretty sure you can too.
Last night1 I finally got the little ‘bot to really make use of the keypad as a modest user interface. The robot is now using the USB cable purely for power purposes, rather than requiring the serial connection to the Arduino serial monitor as well drawing power from the USB port. Now I can just connect the USB cable to a random USB charging device and operate the robot in a meaningful way by using the keypad.
In addition to the keypad direction system described in a previous post, now the “*” and “#” keys also have a usage. The “*” key now starts and stops the Arduino from logging the inputs.2 Pressing the “#” key will play the most recently recorded inputs.
My record/playback system is super hacky and the ‘bot sometimes jitters before carrying out a command. I’ll also have to implement a few additional changes to the design of Y axis before it can hold a pen reasonably stead.
But, it works!
