Modified Ninja

I was not satisfied with either US eyes or a Ledmatrix.
With some -rather rough- modifications I was able to position the 16x8 Led matrix as a mouth underneath the eyes.

I studied ways to have US sensor, buzzer, pushbutton and ledmatrix and I found as the best way this wiring:

A0 = Pushbutton (switches to +)
D0 = GPIO16 US Echo pin
D1 = GPIO4 SCL (I2C)
D2 = GPIO5 SCA (I2C)
D3 = GPIO0 Right Foot
D4 = GPIO2 Right Leg
D5 = GPIO14 US Trigger pin
D6 = GPIO12 Buzzer pin
D7 = GPIO13 Left Foot
D8... (More)

Hi,

I am desperately looking for the STL files of this version of the robot with the HC-SR04 Ultrasonic sensor and the OLED screen that was shown on a video. Can you help me to build this version for my students ?  Where can I find the STL files for this version ? Thanks for advance, David.

Hi Otto Builders

As you might seen a picture of the new design of Otto Ninja has been leaked 😃 

We are improving the design and developing at incredible speed, super fast every day that now you can see a clear evolution.

Here you can compare both the previous version(left) with the new update(right). 

What do you think?
