Hi all!
In this article, we will learn how to calibrate the Draw Me Bot!
So let's get started!
The first thing that we have to do is to connect the robot arm to the computer and to a power source (as can be seen in this video).
Once everything is connected, we need to first set everything up before we can proceed with the calibration. Here is what we need to do:
- Make sure that you have paper ready in the paper holder as well as a sharpie placed in the marker holder module (with the cap off)
- Open the Draw Me app on the mac computer and press the button to turn on the robot arm
- Go to the "Events" tab and create a new Event.
- Go to the "Settings" tab, press the "+" button to add a new line, select the robot arm number from the drop-down list, and ensure that the status will appear as "Connected".
Each line will represent 1 robot arm so if we have more than one robot arm we will need to repeat this process for each arm.
*We recommend turning on and adding to the list one robot arm at a time
- Press the "Calibrate button" - this will make a small window popup which is our calibration window:
Now let's zoom in and see what we have in that pop-up:
- At the top, we have the Home button. If we press it the robotic arm will move to its "home" position.
- Below, we have the Steps length (which is in mm).
Pressing the Z+ button will move the arm up in the chosen step length and pressing the Z- button will move the arm down in the selected step length.
By using those buttons (Z+ and Z-) we will calibrate the robotic arm and set our work height.
For example, if we choose the 20.00 mm Step length and press the Z- button then the robotic arm will go down 20mm. Same way, if we choose the 10.mm Step length and press the Z+ button then the arm will go up 10mm.
What we want to do is to make that the marker placed in the marker holder module will touch the paper in the paper holder and press it lightly.
Once we achieved the height at which we'd like the marker to touch the paper we will press the "Set Work Height" button to save it.

That's it. See how simple?
