- Once the gear is assembled, turn it to check that it moves smoothly and insert the motor. Press each of the motor's wires on the ends of a AA battery to check if the gear moves. (At this point, the battery’s polarity does not matter.)

FabWalker is a stand-alone robot which consists of natural branches and plants. Users collect and attach branches and plants to complete a one of a kind walking botanical robot. The manner of how the robot walks changes according to the length and position of the attached branches. This robot design is an ongoing open-source project modified through many human hands. Please create, document and contribute to this growing robot ecosystem!
- Wire the electronics section that controls the robot’s movements.
(If there are any alternative components, please leave a comment and let us know!)
- Solder pins headers to the Trinket, motor driver and regulator boards.
For the Trinket, you do not need to solder A6, A7 and the FTDI Header.
Also solder two pins to the wires of the motor and battery holder, to make it easier to connect to the breadboard.
- Inserting the pins to the breadboard and placing the board on top will make it more stable to solder the pins.※ Too much heat can damage the chip on the board. Let the board cool down every 5 seconds you solder.
- Upload the following Sketch Program to Trinket.
・Since the standard ArduinoIDE does not recognize Trinket, download Arduino 1.6.x IDE ・Open the IDE・From the menu at the top of the screen, select [Tools] → [Board] and select Pro Trinket 3V/12MHz(USB) ・Do not select the Serial Port
- avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)When this error appears, eject and insert the USB cable and upload the sketch while the red LED is blinking.
Or try using the USB 2.0 Cable.
- Attach the Battery holder next to the gearbox with both sided tape. If the motor’s wires are too short, put it through the hole as shown in the picture.
- Referring to the image above and the Mechanical Giraffe’s instructions (No. 7, 8, 9), assemble the laser cutter pieces with the Mechanical Giraffe’s pieces.
Be careful of the direction and order of the pieces
- The grey pieces (A8) may be hard to insert through the hole, so use a plier.
If A8 does not fit, use a M3 screw and nut instead.
- Gather Material for the Robot’s Feet, such as branches of a tree, flowers and grass.
Or you can use household items such as pens and tooth brushes.
- Insert the batteries, and the Fabwalker will come to life!
It will be better to make a case to cover the electronics. For the WalkingTree version we 3D printed a case, put plants in it and made plants walk.
