Ardubot 2

thingiverse

This little robot is based on David Hrbaty's great Ardubot (http://www.thingiverse.com/thing:603907 and https://github.com/davidhrbaty/ArduBot). The original design was inspired by the MiniSkybot Robot V1.0 (http://www.thingiverse.com/thing:7989), so most of the assembly instructions can be found there. I had to make some changes to get enough power out of the little battery pack, so I modified the design by removing the speaker at the top and replacing it with a box that contains all the electronics, lipo battery, and a power switch. Here's a quick video of it in autonomous mode: https://www.youtube.com/watch?v=0UoXiueChEg Materials Needed: * 1x Arduino Nano rev. 3 * 1x Ultrasonic sensor HC-SR04 * 2x Servo motor Futaba S3003 modified for continuous rotation (see https://www.youtube.com/watch?v=SK8mhnEzcvY). I would recommend either super gluing the potentiometer in place after you have zero'd it or using a resistor instead. * 1x Micro servo motor Towerpro SG90 (available on ebay) * 1x IR receiver TSOP382 or another one (available on ebay) * 1x 7.4v small lipo pack, or you can use the 4xAAA battery pack in the original design and place that under the bot. * 8x 3x2mm (3mm diameter) rare earth magnets (find them on [ebay](http://www.ebay.co.uk/itm/121605717065?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) in packs of 50 or 100 - they're quite affordable) * M3 Nuts - I'm not sure how many are needed, but 40 should be plenty. * M3 Screws - A few short screws are required. I used mostly 10mm and 16mm long screws, but various lengths will do as there is space for longer ones. * 2x 50mm ID x 3.5mm O-Rings for the large wheels. The thickness of the O-ring can be different or you could try substituting it with something like a rubber band if that works. * 1x 13mm ID x 4mm O-Rings. Again, like the large wheels, the small back wheel could use a smaller thickness or some substitute. * On/Off Rocker Switch (5mm wide) - This is optional and you can choose to print the top electronics box with or without a hole for this. I sourced these from [ebay](http://www.ebay.co.uk/itm/251390016446?_trksid=p2057872.m2749.l2649&var=550316227968&ssPageName=STRK%3AMEBIDX%3AIT). * Heat shrink to cover the exposed soldered wires See the instructions for some more details.
