The inception of ‘WOT - A -BOT’ started with a simple brief to construct an amphibious robot employing clever yet innately simple paper folding techniques. It took cues from various Bio-inspirations throughout design development with the motion of a Manta-ray as the most prominent influence. The project revolved around developing a single paper fold hinge mechanism contributing to both a crawling motion as well as a swimming motion. The primary goal was to keep the geometry of the mechanical hinge as humble as possible yet at the same time extracting a sophisticated fluid output motion.

Hinge construction
The making of wot-a-bot involved both design dexterity as well as technological skillsets and CAD modelling to map out the mechanical motions of the 6 Bar, Single degree of freedom hinge design.
Design Progress
* Pair up
* More surface area gives better output motion
Electronic Controller
In order to synchronise the motors for better control, we used processing over Bluetooth pairing whereby we achieved individual motor control using the laptop keyboard. We set-up keyboard aliases to increase/decrease or change the direction of the rotation.
Vacuum form body part
The electronics where then packed into the vacuum formed plastic case and sealed with silicone consistently. This step gave us some more motor control however the Bluetooth pairing was not as accurate. Nonetheless alas we had our Wot-a-bot.
