New Legs for Shellmo !
RepWalker is a low cost and unique motor module.
You can make RepWalker by your 3D printer with ease.
By your 3D printer
I made RepWalker by Replicator2 at Low resolution setting (Layer Height:0.3mm, Infill:10%, 250℃, PLA).
You need only 96x40x26mm working space for printing all 3D parts.
RepGadgets for Shellmo:
We're trying to renovate the making cost of Shellmo.
We plan to create these Gadgets for you !
3D printable gearmotor. We can use standard FA130 hobby motor for this.
3D printable remote controller. It was made with 3D printable parts, screws&nuts and electric wire only!
We can controll Shellmo without Arduino with ease.
And, after play Shellmo by this controller, you can customize Shellmo for controlling with Arduino with ease.
3D printable battery holder with 3D printable parts and electric wire only.
3D printable touch sensor with 3D printable parts and electric wire only. For this, Shellmo can walk itself without Arduino.
We hope robot beginners and students to make and play Shellmo with our RepGadgets & RepWalker with ease by their 3D printer at first, and after it, we hope them to customize for controling Shellmo with Arduino and their phone!

3D Printed parts:
I will upload short movie of RepWalker soon!
All 3D parts for making RepWalker
Please print this: .stl
This is an engine of RepWalker. Basically, you can connect this motor to motor driver and Arduino for controlling by your Android phone.
8mm M3screws and nuts
I used 24 of M3 screws and nuts to RepWalker. I used 8mm legth screw, but this is the at least length.
You can use also like 10mm, 12mm M3 screws.
8mm M3Screws: Pololu
You need about 150mm length jumpwire for connecting gearmotor to motor driver or battery directly. I recommend to use flexible jumpwire.
You can use 2xAA battery holder for walking test.
I thought, it is suitable about 3V for test. So, I choosed 2xAA battery. But, if you plan to control RepWalker with Arduino, I recommend you to buy also 4xAA battery holder.
2xAA BatteryHolder: Sparkfun
4xAA BatteryHolder: Sparkfun
You can use breadboard for walking test of module. After it, you can install breadboard to Shellmo.
