ESP8266 WiFi controlled Hamster

Using ESP8266 WiFi modules to remotely control
Stepper motors and other cool stuff

Grafting an ESP8266 WiFi module into a $10 3D printed robotic Hamster.
This is just a glimpse of a project I am working on right now.
It uses a single ESP8266 series 12 WiFi module to control 2 stepper motors.
The hamster creates its own server with a tiny control panel webpage.
Its part of a mapping control system , with the idea of using multiple hamsters
(Maybe even scaled up mega hamsters with Nema17 motors)

Run through on the system.... and operation and first glimpse of its accuracy.

  • 1 × ESP8266 series 12 Wifi module - the heart of the project
  • 2 × 4-Phase Stepper Motors with 2 ULN2003 Control Boards
  • 2 × 18650 5000mAhr lipos

  • 1
    Step 1

    At last everything has come together ...

    Unknown Object

    This is just a stepover project to prove the roundrobin of adding ESP8266 WiFi modules to remotly control Stepper motors and other cool stuff.

    Starting with the On/Off switch, it is a split Swiss cheese magnet which operates a reed switch behind its sharp teeth.

    The Hamster body parts were designed in Blender using Meta-Balls.

    ......and cured in Cura....

    ... notice the middle circular cavities which house 2x 3000mAhr 18650 lipo cells (mumpf-mumpf)

    I printed it in Glow PLA it will creep you out if caught un-awares,,,,,

    The hamster is short sighted , so I crafted a pair of rose coloured spectacles for it.

    Design time :-

    Real time :-

    The wheels troubled me .... as I wanted paws...... so a compromise was made with a spoke effect with rubber o-rings for wheely good traction.

    At the heart of the Hamster sits an ESP8266 WiFi module series 12 which controls two stepper motors.

    The red/orange glow you see are the stepper drivers (neat that each phase has a LED, great for debug)

    The ESP8266 is programmed using the Arduino IDE (please refer to my walkthrough on how todo this)

    The program enables the Hamster to host its own standalone server which which you can access from another WiFi enabled device.

    I am using my netbook to access the Hamster software , when linked the hamster transmits its web gui (a bunch of click-able buttons) back to my net book where it can be controlled.

    Code (provisional) can be found here <ESP8266 Hamster Code>

    Now I want to intergrate it into MRL ..... where to start......

Great project.

Can you please add to code, to web page control - video stream from phone that attached to robot's front? Think that will be much better.

  Are you sure? yes | no
