How about using the popular micro:bit to make a Otto robot? this is how this robot came to life combining to great platforms and adding more articulations to create a new member of the Otto family.

This a remix of the original Otto robot with the idea of using a micro:bit board instead of Arduino, it has 8 servos to control each joint including arms, LED mouth and Neopixel eyes.

Graphical programming with MakeCode makes it easy to control the robot's features

The control of the servo motors it is more difficult in this robot because the Python code language use in micro:bit is not compatible with the original Otto robot code, which was developed for Arduino, using C++ Libraries, instead you will have to create those movements from a series of blocks in MakeCode intending to move the servos angle by angle in combination to walk and dance or use Python.

Suitable for fans who have a certain programming foundation and hands-on ability., it may be too hard, specially if you have not use micro:bit before.

For slicing and generating the g code for the machine FREE slicer software like PrusaSlicer or any of your preference (If you are outsourcing the printing no need to worry about it).

After printing you will need to clean a little bit the legs and feet areas that fix the motors (generally) depends of the cleanness of your print.

it should take around 12 hours to print a full set of parts for one Otto micro:bit

MakeCode by Microsoft
https://makecode.microbit.org/
Examples to start:

For more you can copy or import the .hex files into MakeCode micro:bit then you can modify the blocks parameters in the examples

RobotBit board is capable of controlling DC motors, step motors or servos.

On the board is an electric bell, multi-color RGB LEDs and handy 3Pin-conclusions for all ports of entry/output of the micro:bit board. These connectors allow you to connect to micro:bit most of all known additional devices for Arduino and other popular boards.

The board is powered by a 18650 battery and has a built-in charging module to charge from any USB port. It is possible to connect the external power of the battery with a voltage of no more than 5B.

The circuit board has standard Lego holes for attaching the board to the Lego-designer's details. Versatility makes this board an indispensable driver for micro:bit board and create your own DIY projects.

MakeCode Expansion

In an online editor, Makecode, add a Robotbit extension through keyword search (1). In the PC version of Makecode you can find the Robotbit extension in the same way. Click on the extension window to install it (2), after which the extension will appear on the Block Panel in the editor.

Once you've unpacked the RobotBit board in the first place install the 18650 battery, pay attention to the polarity (there is protection against incorrect installation). You need to activate the battery power control system by pressing a small button next to the battery compartment (batteryAct). Every time you change your battery or board goes into protective mode, when the battery is discharged or hangs with the blue LIGHTS on, you need to press this button to get it back to normal.

RobotBit Fast Start

Place the battery on the RobotBit board, paying attention to the battery polarity pattern and the pattern in the plastic compartment, do not confuse.

Install micro:bit in the connector on the RobotBit board, keeping the right side of the setup

Click on the small "battery act" button to activate the battery. You can also use this button if the RobotBit board is stuck.

Switch the tumbler to turn on the built-in battery 18650

Open MakeCode Online Editor (1) and select Extensions (2)

Enter in search of the word robotbit

Click on the extension that appears and it will automatically be added to the workspace.

A special section with blocks for the RobotBit board appeared in the editor's window

Add blocks to the workspace, put the right I/O ports in the block settings that connect servos, motors, etc.

Before you download your finished program, remember to connect the micro:bit board to your computer (it's a micro:bit board, not a RobotBit fee, because the usb connector on the RobotBit board is only for charging the battery). The micro:bit fee may remain snulged to the RobotBit board at this time.

After clicking on this button, you'll see a window that's going to say where to go, save the file to the MICROBIT store, which will appear as a removable disk when the board is connected to the computer.

Create the code as shown in the image below and click the Download button.

Once you download the program and copy .hex file on the micro:bit board, the heart will start beating on the board!

Assembly instructions

Check the instruction manual folder in the files tab

The first point to write first is that each servo should be installed with an initial position of 90°.

*UPDATED 10/07/2018 - Added an image of how I wired up Pia (raspberry pi/ circuit playground and the batteries)*UPDATED 9/16/2018 - updated arch_y_manifoldfix.stl in an attempt to resolve manifold issue. There isn’t a problem printing in Cura but may be an issue using Simplify3D. I used blender to identify problem areas and there still is a manifold issue. I recreated the object in sketchup so perhaps there is an export issue when creating the STL.UPDATED missing STLs July 4, 2018 and added STLs for battery mount, PI3 and PCA boardVideo in action: https://www.youtube.com/watch?v=bRn4ZjMaChUAfter seeing Alonso Martinez’s Mira robot on You-Tube, I had to have one but couldn’t find it anywhere. So, I designed my own version of it and will be uploading STLs and make the software that I’ve written for it available either here or github.In a nutshell, it is two concentric shells with 3 servos to control x, y and z axis. It runs on a raspberry pi zero w, a pi camera and a PWM board from Adafruit. Internal parts are held in place without screws; just 3D printed blocks and 1/4″, strong magnets.Currently, I’m not using battery power, but that is in the works.I went through 24 iterations of the design and printed many of the parts several times. At the time, I’m please with the outcome.What this uses:1 - Raspberry Pi Zero W (each $5.00 from Microcenter, Tustin CA)1 - Raspberry Pi camera ($24.95 Microcenter, Tustin CA)3 - SG92R MicroServo (each $5.95 from Adafruit)1 - Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685 ( $14.95)1 - Circuit PlayGround Express (each $24.95.. Mine was free when I bought my 3d printer from Adafruit)2 - ProMAG Neodymium Magnets (.25″) in pkg of 6 ($4.95 from Michael’s) Update Although the model was originally designed for the Pi Zero W, I added support for using a PI 3 because the OpenCV software for image recognition runs a bit better on the faster computer.Software:The raspberry pi is running “stretch” lite (no gui) and OpenCV for controlling the camera. I’m writing the code that control the servos using Python. All source code, STLs and SketchUp model is now available here: https://github.com/BtreeComputingServcies/pia-the-robot. Circuit python is running on the Circuit Playground Express and will also be made available when completed.I updated some of the STLs after I first uploaded to the site.
