Pushed the Google Sketchup design to the ShopBot CNC machine
The ShopBot does all of our cutting for us
Jason's first prototype was a small platform with big wheels
Note the rear caster with a brake
Back to the CNC for more parts
A close up look at the windshield wiper motor assembly
From overhead we can see how the drive gears work
A close up of the main drive gear on the wiper motor
A look from below
Now with a bigger version 2 that has more space for a laptop and Gadgetboard
A close up look at Jason's Gadgetboard design that takes commands over serial and drives the motors
Getting things wired up for a test run
We used a power supply to watch amps and voltage to see the current draw at different speeds
Engaging the gears for the first time
Sending serial commands out from the laptop. Here we see a command for "p 8 0" which is "Pulse Width Modulation on port 8 set to 0" or "stop" basically.
With a battery in place Jason writes up a quick demo script to put it through some twists and turns.
We used a typical emergency car battery for 12V power.
Ready to go!
Ooops, a gear came loose. A quick tightening gets us back on track.
A look at the gear connection.
Happy Maker after a succesful run of the Boxbot!
Ryan learns how the Gadgetboard programming works and gives it a spin.
Comtemplating the next phase...hmmm, what will he come up with?
