My latest tankbot has been designed to be a larger vehicle but printable on a small scale printer.
A number of issues with the other tanks have been overcome (hopefully) with this one.
First and foremost it now runs on two standard sized continuous rotation servos. You can obtain these with various torque settings to suit your needs!
Secondly the tracks are specifically designed to be joined with 1.75mm filament offcuts. These save the need to order expensive stainless steel rods and because they flex, they hold themselves in without need for glue.
Thirdly I have designed it to bolt together rather than being glued – so that changing parts – or reconfiguring it is now possible.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
