Otto DIY+ Arduino Bluetooth robot easy to 3D Print

Otto DIY + would be the improved and advanced version of original #OttoDIY, the idea is to have the same base features DIY robot + Bluetooth control and programming + metal gear servo motors + optional rechargeable + changing modes by touch sensor + sound sensor + ...?

The exciting part is that we are doing open development with makers and hackers around the world so we are open to ideas, not only from experts, you can join us with, feedback, social share, testing or any other contribution that you might think of.

follow our live build video!

Start to play with the APP!

Baud-rate for programming module is 9600 or 19200 or 38400, depends on a module. and the code you are using

The BT code for our APP has 9600 baud-rate so BT module must match that speed to be able to communicate with Arduino Nano via serial interface(UART).

Main Code:

Upload this code with the Bluetooth module disconnected

After successful upload connect the Bluetooth module and it will be ready for pairing with your phone.

Android APP:

For Android download for free here.

For iOS download for free here.

If the APP didn't work is probably because the Bluetooth module came with a baud rate different to 9600bpm so you need to setup or change in the code.

Code with Blocks

The easiest to code your own Otto is by using one of our Blockly based software.

For more advanced coding here there is some basic programming with Arduino IDE:
