TypeBot is a NodeBot that can type on a keyboard. This folder contains the source code for TypeBot and two helper applications. To run these examples, first install the dependencies:
npm install
To run TypeBot, connect your arm's Arduino and run:
node typebot.js
For more details on TypeBot, be sure to read the make book!
It is often necessary when working on the arm to remove and re-attach segments. Doing so requires that the arm segment be re-attached at the appropriate angle, however. The align servos helper app will set all servos to 90 degrees. In practice, it's pretty easy to eyeball a 90 degree angle, so this makes it easy to re-assemble the arm. To the align servos app, connect the arm's Arduino and run:
node align_servos.js
One of the trickiest parts of creating TypeBot is coming up with the initial estimate of servo angles. This app will generate estimates for all of the servos for each key. It uses a set of parameters about the keyboard and uses some basic Trig formulas to calculate an estimate of the angles. To generate the angle estimates, first edit the constants defined at the top of "generate_angle_estimates.js" if need be. Then run:
node generate_angle_estimates.js
