Larger Version of Vacuum Robot

thingiverse

since I have a large build platform, I decided to give it a try and re-design the body of cesnietor's robot. However, this requires a 300mm bed, which will not fit on a prusa. To build this or the original version, you need to go to https://www.thingiverse.com/thing:2288841 as these were unchanged. But to assemble this, you'll also need that link and the code and assembly instructions are at https://www.instructables.com/id/Build-Your-Own-Vacuum-Robot/. If you build the robot with either body, it's a great way to learn how to code if and when you decide to add the extras listed on instructables. For added support and choice, I added a 1mm thick wall where the sensors go, which helps with printing and also allows you to use 2 sharp sensors or 4 - just remove the required walls. The battery is a 3s lipo, and this body will fit a 2.7mah comfortably. This design of robot by cesnietor's just proves that, with an arduino and a 3d printer, you can pretty much achieve anything. I printed his version, and it works great. It's a shame that the space for the arduino uno is just 10mm too short for a mega. If you'd like to use magnets for the bumper instead of gluing it, use the file listed in the files section and the file you need from the remix entitled larger bumper. To mine, I removed the bumper and added many cheap sensors from http://www.ebay.com/itm/New-Obstacle-5Pcs-IR-Infrared-Avoidance-Sensor-for-Smart-Car-3-wire/162626761472?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649. I also swapped the battery for a 2.7mah 3s lipo battery, motor encoders, lcd display, mega 2560 instead of arduino uno - although the usb cut out is not on the stl file, so I cut my own. A small bit of the print needs removing on the inside, and I needed to higher the motor mount, which is why there's a stl file that doesn't mean much - just print and glue it on and extend the height if you're using a 2.7 battery. In the near future, I'll be adding 2 x 12v mini gear motors from digikey and some brushes from http://www.ebay.com/itm/332153230543 which mount so there's a brush under the robot on either side of the dust entrance hole - which are on many robot vacuums on the market.
