The first and second letters are shown in figure 21. These are close-ups of the letters H and A. My Globe Plotter Bot™ is set-up that the pen holding servomotor is connected to P1 (servomotor 1) and the rotating servomotor is connected to P2 (servomotor 2)

We set the starting position for the two servomotors at 145 and 75 respectively. Set Speed selector to 10. Set the command mode for Scripting and Step mode. This selection allows you to have two servomotors move simultaneous. Enter number 145 in servomotor 1 text box and hit the tab key. This will move the pen holder to position 145. Enter number 75 in servomotor 2 text box and hit the Tab key. This will rotate egg to position 75.


Step 1 Enter # 165 in servomotor’s 1 text box; hit tab key then click “add step” button.
Step 2 Enter # 155 in servomotor’s 1 text box; hit tab key then click “add step” button
Step 3 Enter # 95 in servomotor’s 2 text box; hit tab key then click “add step” button
Step 4 Enter # 165 in servomotor’s 1 text box; hit tab key then click “add step” button
Step 5 Enter # 145 in servomotor’s 1 text box; hit tab key then click “add step” button
Step 6 Enter # 105 in servomotor’s 2 text box; hit tab key then click “add step” button


Each time you hit the Tab key, the servomotor responds to the entered command. Each time you click on the “add step” button the command is written into the script. We finished written the H character and are in starting position to write the A character.


Step 1 Enter # 155 in servomotor’s 1 text box; hit tab key then click “add step” button.
Step 2 Enter # 165 in servomotor’s 1 text box; hit tab key. Enter # 115 in servomotor’s 2 text box; hit the tab key then click “add step” button


We need a little explanation for this last step. We moved two servomotors positions before clicking on the “add step” button. What this did is too allow those two servomotors to move simultaneously, During Playback, to write a diagonal line. However when entering the step each servomotor move independently when the tab key was entered. So diagonal lines will only be drawn properly on playback not during recording. Let us continue.


Step 3 Enter # 155 in servomotor’s 1 text box; hit tab key. Enter # 125 in servomotor’s 2 text box; hit the tab key then click “add step” button
Step 4 Enter # 105 in servomotor’s 2 text box; hit tab key then click “add step” button
Step 5 Enter # 125 in servomotor’s 2 text box; hit tab key then click “add step” button
Step 6 Enter # 145 in servomotor’s 1 text box; hit tab key then click “add step” button


Once you have finished entering your text or graphic program you can load an egg into Globe Plotter Bot™ and let it run.
