3DoT Robotics

Dedicated to supporting the development of robotic 3D printed objects

Current electronic microcontroller board solutions simply do not factor in the ten of hours required to print even the simplest robot. Our Micro-footprint 35 x 69 mm (1.38 x 1.73 inches) all-in-one Arduino compatible microcontroller board means moveable 3D objects can finally be designed and printed.

The 3DoT Robotics board integrates everything you need to autonomously or remotely operate your own 3D printed thing.

Programming

The brain of the 3DoT robotics microcontroller board is the ATmega32u4, the same processor used in the Arduino Leonardo. Programming the robot is similar to the process with the Arduino Leonardo. Both processors have built-in USB communication, eliminating the need for a secondary processor. During programming and debugging, this allows the Robot to appear to your computer as a virtual (CDC) serial / COM port, while simultaneously communicating with your smart device over BlueTooth.
