Edgar - based on BoeBot

this was my first robot. though it was a kit and i didnt have to create chassis myself, it taught me a lot. after finishing the book and the exercises in it i started to experiment with various sensors different from those in the kit.

i wanted to make it for the line following competition. first try was to use photoresistors for following black line on white board, it kinda worked, but was very dependant on ambient light.

i then switched to CNY70 (5 of them in row) for line, 2 IR LEDs and 2 PNA4601M (from BoeBot kit) one pair fwd and one pair left to enable pass obstacle on track from right.motors, wheelsand other parts are from the kit as well.

i just wanted to put this robot here for record, now i am working on the other one, that i am putting together myself.

two videos i attached: one from competition and the other one just playing with the crawler kit at home.

cost to build is sum of the boebot kit, the crawler kit and all the things i needed - sensors, resistors, capacitors, cables, etc. time to build is rough estimate as well :) including the excersises in the book. otherwise it would be less then 100.
