Here is the assembled tread and motor mount. Using a 12V 2A power supply I tested each unit and found that they work nicely. The motors are 30 rpm, so 1 rotation of the wheel every 2 seconds resulting in a nice slow robot that should be easy for me to control with the Raspberry Pi.
The final assemlby is below.
Right side up.
Next I will be building mounts for the DC motor controllers and the raspberry Pi.
I have created a wheel design for driving the tank tracks for my mini Raspberry PI robot. The STL file is available here on tinkercad.com.
Also found a couple worm gear motors that will run at 30rpm at 12V (Unloaded) on Amazon.ca . They have a 6mm D-shaft that is a little short, but should be ok.
Next step is to build a 3D design for mounting the motors and holding the wheels in position within the track.
Will try to post some pictures soon.
A friend of mine is really into 3D printing, it looked like so much fun that I bought a ‘Wanhao Duplicator i3 Plus’ for $649 from the same place he got his, Spool3d.ca. It has been a great experience so far. I have been printing almost non-stop for the last month! This printer is very well built and I can definitely recommend it to anyone wanting to get started.
I have been using tinkercad.com for all my designs, here are links to a few of the models I have built. I am slowly building up a tank type robot for my Raspberry Pi. Fun stuff!
