The cleaning robot is designed to have 2 modules, the movement module and the cleaning module.

 

Putting them together

 

 

How it works (Cleaning Mechanism):

• Simplifying the idea of a “self-cleaning mechanism”, we decided to use a washable and reusable cloth. (Coconut Cloth)
• The water pipe will spray out water/cleaning solution onto the floor. The cloth would then wipe up the dirt and grime on the surface of the floor. 
• After a set interval of time, the clean cloth roll (left) will dispense out clean cloth while the dirty cloth will be rolled up on to the dirty cloth roll (right). This ensures that a clean cloth will be used to wipe up the dirt at any point in time. 
• The cloth is then detachable and able to be washed using a washing machine. It is washable and reusable up to 100 times. 

How it works (Swapping Mechanism):

• Sliding wheels on the sliding mechanism together with the caster wheels allow the the cleaning module to slide in with the movement module. 
• A pin and hole will act as the locking mechanism to hold the cleaning module in place, allowing for both the cleaning module and movement module to move together. 
• With this swapping mechanism, new cleaning modules can be created within the constraints and be attached to the movement frames for different purposes (Eg: Vacuum, Scrubbing, Floor Polishing etc)
