The Broomba is Born!

The Broomba is Born!


Today we met up to discuss the mechanical aspect of our sweet sweeper robot, which we have named the Broomba. Our initial idea was to have a remote-controlled robot with the broom on the front to push around dirt. The broom in the front would also maybe move back and forth, controlled by a motor. Today we refined our idea to make a more efficient robot. 

The Initial Idea
We decided to change the broom from a push broom to a circular spinning brush. The brush would be connected to a motor which would make it rotate, which would collect the dust and push it into a dust pan that was located between the brush and the chassis. 

A few notes on the design

The brush is going to be attached to the chassis of our robot with 3-D printed and laser-cut pieces. The chassis has different holes in different sections of it, so a custom-printed part will be needed in order to securely attach it. 



We also toyed with the idea of different attachments for our Broomba, like a scrubber that shoots water, or a Swiffer attachment. Possible Swiffer funding??? ;)

Connor Gathers Assorted Goodies

Connor is not an Electrical Engineer,

but he decided to take some time this weekend to rip apart some devices, and salvage some components that may be useful.


Seen above are some tools used to get the job done, some cool motors, buttons, switches, and wheels, an IR remote control, a power cable, and a battery holder.  We will probably use some of this stuff.

Team We Are Not Electrical Engineers decide on building a sweeper robot!

We are planning on building a sweeper robot. It will have a broom on the front and will be remote controlled.


Here are some Arduino projects that we looked at that we found intriguing:

A "Liquid Lifebar", which consists of a glass tube that has water in it. While the player plays a video game, the water level in the tube increases and decreases and changes color from green to red as the player gains and loses health.




A light up umbrella, that lights up in specific points where the raindrops hit it.


An LED coffee table that lights up when it senses something over it.

How he did it:


A "Crystal ball" that changes color when it senses heat.

Solar tracker


Motion sense water gun

Motorized pencil sharpener (hand-crank pencil sharpener hack) using light sensors, 3d printed gears, and DC brush motor
