So I've build the tutorial robot and me and a friend want to do something more challenging. We've decided to re-use the parts of the tutorial robot and make a similar robot, this time with a vacuum cleaning goal. It's not the goal to make one for personal use or even a good working one, it's for a school project so if it moves around and vacuum cleans a little bit it's good enough.
Raw sketch of the body, wheels and sensors (Sensors are red, wheels black, body is large rectangle):
Obviously not to scale, some things are larger than in real, some things smaller, some things further apart, closer etcetera. I'll build the body so it can house all the neccesary things from actuators to microcontroller. Designed by looking up stuff on the internet.
It is quite simple: The brush sweeps up dust unto the dustpan and on the other end is a vacuum sucker (I have no idea what the English word is) which sucks in the dust that gets sweeped up, this is simple in design that helps get the job done with a smaller sucker thing. Once again, designed by looking at other stuff on the internet.
I would like to know what you guys think I should add/remove or do different. I also was thinking about the power. It's going to need more power than the tutorial robot, obviously. So how do I add more power? I can't simply add more batteries to the microcontroller/project board as it is designed for 4,5 volts and stuff like the sucker is going to need a lot more. How do you do this?
