Mocoro vs. WonderBorg

Recently I found an interesting cleaning device, the CCP Microfiber Mop Ball Mocoro. Videos of it cleaning the house or entertaining cats are all over the internet.

It’s movement and sounds¬†instantly reminded me of the Bandai WonderBorg, a programmable robot for the Bandai WonderSwan (and Windows PC).

The WonderBorg has been released in different shapes and colours, according to the sticker mine is flavour 02. With the included software RobotWorks and a WonderSwan/Color/Crystal you can programm the little robot after assembling it. Make sure to get version 1.5 of RobotWorks as version 1.0 is Japanese only.
I assembled my WonderBorg a couple of years ago. Unfortunately some of the pictures I made back then are blurry. This is what’s in the box:

If you don’t read/understand Japanese you can use the English manual for the Windows version for assembly instructions.

After WonderBorg’s first steps I noticed that it constantly loses it’s wire legs and antennae – if it was moving or sensing at all. I replaced them with the included plastic wheels and antennae.

Even though the WonderBorg is eagerly trying to collect dust and dirt it is no match for the Mocoro. Let’s see what is inside of it:

Mocoro uses three AA batteries. The cover of the battery compartment hast a weight attached to it.

On the opposite side is a cover to protect Mocoro’s brain and a switch that turns it off instantly.

On the PCB we see some transistors, a capacitor, a jumper, a switch and four connectors: Motor (red), batteries (white), on/off/sound switch (yellow) and speaker (black). On the back side there is an IC blob, some SMD components and bad soldering.

And this is it, the motor and gears that makes Mocoro move. No sensors, no magic – just a simple motor that turns in one direction for about four seconds, stops, and turns back for about four seconds.
