BoBotto the Humanoid robot

First off i would like to give a huge shout out to the maker community the bob remixes including OttO have been amazing to see, i never dreamed of this sort of response. So BoBotto is a remix of all the great remixes. I've taken arms from the humanoid style robots and added them to the otto design then tweaked the appearance to resemble the OG bob the biped robot

While i owe many people credit for their base work and inspirations, that list would be miles long.

My name is Kevin "The Bobfather" Biagini and i am the creator of BoB the biped. I started tinkering way back when and haven't stopped. I have experience in 3d design, fabrication, and electrical circuits.

Project Inspiration

This project is inspired by the OttO project and all the other great BoB remixes. It came to life because a very simple reason, the contest was open and may daughter wanted a new BoB to build and call her own. so i took the great OttO platform and remixed it to look like my BoB robot, changing up his lines and using parts of the feet and legs to give him arms (a request i've always gotten)..

Bill of Materials(BOM)

Here there is a list of the materials you will need to build BoBOttO.

1x Arduino NANO Shield I/O

1x USB-A to Mini-USB Cable

1x PING Ultrasound sensor (HC-SR04 head file coming soon)

6x 9Gram servos either plastic or metal geared

24x Female/Female Jumper Wires

1x 800Mah 7.4V lipo (4xAA battery holder will also work)

8x BoBOttO 3D printed parts

1x Small Phillipis screwdriver

5x 3mm LED (optional for mouth)

Fabrication

What digital fabrication machine is the 3D design to be fabricated with?

BoBotto was printed on a prusa i3 in pla

The legs and arms where printed standing tall with the flat closed ends on the print bed.

No sanding or filing is required as long as your printer is semi decently calibrated.

3D Design

What CAD software did you use?

The Bobotto remix was done using the stp files and Solidworks

Layer Height: 0.22mm

Wall Thickness: 0.8mm

Top/Bottom Thickness: 0.6mm

Infill Density: 10%

Printing Temp: 210c

Electronics and programming

Bobboto uses the cheap and easy to get Arduino nano with shield.

testing is being done with a Pi zero W and servo shield. using the google api bobotto could become very interactive.

Bobotto is programmed using wiring in the arduino IDE

As a good practice you should check your electronics and software in your computer, before assembling all robot to avoid having to disassemble the whole robot to fix something!

Assembly Instructions

One of the best parts about BoBotto is the ease of assembly. BoBotto goes together exactly like Otto does. For instructions check out Otto DIY!
