Tito - Arduino UNO 3d Printed Robot

Tito is a Biped dancing DIY robot, derivative from Zowi and Bob, basically has been adapted to an standard Arduino UNO board with easier connections and supports. It was the first iteration for Otto DIY (www.ottodiy.com)

Arduino UNO board or compatible (in my case a DFRduino UNO)

Breadboard

Buzzer

Futaba servo S3003 x4

HC-SR04 Ultrasound sensor

Powerbank (optional)

Nut M3 x20

Screw M3 x20

3D printed Head

3D printed Base3D printed Leg x23D printed Foot R3D printed Foot L

Tools: 3D printer, Allen key and screwdriver

3D .stl files here: https://wikifactory.com/+OttoDIY/tito/files Find a way to 3D print the parts, they are designed for no supports, so it is very easy to print with 20% infill and 0.2mm resolution.

Since is Tito is completely opensource you can find there the 3D model design files.

There is many was to build Tito, but one recommendation is before the connect the servos is to assemble the servo disk pieces to the legs, then put the servos in the body and the feet..

Connect the servo motors in 2,3,4,5 digital outputs refer to the same wiring of other Ottos, HC-SR04 Ultrasound sensor (trig for pin 8 and echo for pin 9).

For more details just use the same connections used in Otto DIY robot

In the picture the cables are disconnected but the idea here is to upload a code to the Arduino UNO board that will put the all servos in 90 degrees and then match the right angle for the crank discs in the body and the feet. Tito should be in a position like the photo. then you can fix all the servos with the screw axis.

This design make it easy to fix any Arduino Uno compatible board (in my case a DFRduino UNO) in the head part, you can use up to 4 screws.

If all connections are secured you can close the head part and fix it to the body using the lateral screws.

Just connect your USB cable to Arduino UNO and upload the codes from our Otto Blockly software. There are many examples for the robot like walk different directions, ultrasound, raise, tilt and dance.

PLEASE DO NOT COMMENT IF ANY QUESTION, i don't get notifications by instructables new comments so if anything please post in our forum builders.ottodiy.com otherwise it will take a lot of time for me to see it
