### DrawBot now supports GCODE

Specifically, G00 – rapid move to X,Y G01 – normal move to X,Y G02 – planar clockwise arc to X,Y around I,J G03 – planar counterclockwise arc to X,Y around I,J Fx.xx [...]

### Linear Interpolation vs Trapezoid Motion Interpolation

As mentioned in the DrawBot Overview, Linear interpolation [sourcecode]Position = Here + (There – Here) * time_passed/time_total Time = ( There – Here ) / vmax[/sourcecode] is great [...]

### Drawbot: Overview

The Makelangelo is a great way to start learning about robotics. It has two motors mounted at the top of a wall. The motors have bobbins wound with string. The strings are connected to a plotter, [...]

### Drawbot + Halftones

I’ve had the halftones code since v1 but only just now got the chance to test it out. My drawbot is creating images that are a little too tall & thin. Anyone know why?

### Building a Delta Robot Part 2: Build a theoretical model

So I’ve decided what my robot needs to do in Part 1, and now I’m going to build a virtual model of the delta robot and program it there. That will give every user an intuitive visual [...]

### What are “steps per turn”?

Dear Dan, Recently I am working on the Delta Robots. I look your forward and inverse Kinematics of the delta robots and it help me a lot. In your application of forward and inverse kinematics [...]

### Drawbot Calibration, part 2

The test pattern is based on one I saw being done by the incredible H5GBSD.

### Drawbot Calibration

I’ve finally got tests working on the drawbot, here are some pictures of calibration efforts. View calibration gallery here.

### Drawing Lines, Arcs, and Halftones with a Wall Hanging Arduino Drawbot

Download the code here 2013-11-26: updated link to github project! Among the various features are… Verbose output: Debugging line and arc drawing took a lot of work and I see no reason to [...]
