01 / MECHANICS
Printed in pieces.
The body, mirrored leg parts, spacers and head have separate design files. That makes the mechanical structure visible, from the central shell to the curved feet.

OFF THE SCREEN. ON ITS FEET.
A little robot,
in its element.
FROM THE 2018 WORKBENCH
iOlly brings a compact four-legged body together with a large, rounded head and curved feet. The original photographs, prints and motion demo show the design making the jump from CAD to a physical robot.
This page follows the documented 2-DOF v1 build: two driven joints in each leg, plus a separate head channel. Its character comes from the combination of its silhouette, stance and programmed movements.
FROM MODEL TO MAKER
The shape of
a small character.
02 / MOVEMENT
More than walking.
The archived firmware defines walking and turning alongside poses and gestures such as hello, looking around, nodding and dancing.
03 / CONTROL
A Wi-Fi connection.
An ESP8266 handles the original command interface. Movement requests are received over a local wireless connection and passed to the motion routines.
The movement list describes the archived firmware. Each routine has not been re-tested for a new release. The front piece is named “camera” in the files; camera hardware and vision functionality are not established by this archive.
A CLOSER LOOK / 2-DOF V1
Piece by
printed piece.
The original component views show how the body, joints and head are divided. Open a drawing for a closer look. These are reference illustrations; the complete STL package is not released here yet.
UNDER THE SHELL
Nine channels.
One small controller.
The v1 source configures eight leg outputs and a ninth head output. The body’s motion is coordinated by servo oscillators; commands select the movement or pose.
- ESP8266 / Arduino C++
- The archived controller code uses the ESP8266 Wi-Fi and Arduino Servo libraries.
- Eight leg-servo channels
- Two driven joints per leg, arranged as an inner and outer channel on each of the four legs.
- One head-servo channel
- A ninth output, labelled “camera” in the source, moves the head assembly.
- Printed body, legs and head
- A split body shell, mirrored leg components, curved feet, spacers and a separate head assembly.
- Local Wi-Fi commands
- The firmware creates an access point and receives numbered movement commands over HTTP.
Exact servo models, the power supply and a verified wiring diagram still need documenting before this becomes a reproducible build guide.
THE PROJECT NOTEBOOK
Two robots.
Their own build stories.
THIS BUILD
2-DOF v1
Prototype photographs, a demonstration video, component drawings, a 16-file STL set and Arduino C++ source document this version. The STL set includes a separate tibia print-layout file; 16 files does not mean 16 pieces per robot.
A SEPARATE ROBOT PROJECT
iOlly 4DOF
The orange-and-black 4-DOF quadruped has its own prototype and progress videos. Its 11 component drawings, including the neck, tars and battery cover, now have a home on its dedicated project page.
