The very first time i think at what a robot does.
that use a water rocket to be an anti missile blocking and raining the earth.
and there is another anti missile robot on boarded the flying water rocket
controlling water rocket(part_3) too !
the water rockets will not fighting each other because of the rockets
don't burn any fuel and they don't emitting light !
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Material
it's every part and elements
Step 2: Prototype With UNO
connecting the heart of robot to it's every part
Step 3: Prototype of Launcher Gear Driving by 2003 With UNO
Step 4: Auto Turnning Platform With CD
use an old (wasted) CD, a paper clipper, a washer, a hand drill.
and the PCB read the signal for next move.
Step 5: Connecting Sensors
the platform read POS_v (+5 == LDR == 10K == GND ) from 10K OHM
and read POS_h (+5 == LDR == 10K == GND ) from 10K OHM
so that 10K connecting to UNO PIN A2,A3
Step 6: Connecting the 1602 Displayer(may Remove Aswell)
Step 7: Testting the Robot
the water rocket launcher robot with UNO.
the water rocket controlling robot with mini.
Step 8: Coding
the most complex part it's here !
there are three state(s) and 2 speed(s) :
1)Target is right side upon luncher ==> do the turnning forward with slow.
1')Target is right side upon and near luncher ==> do the turnning forward with fast.then delay 20ms.
2)Target is left side upon luncher ==> do the turnning reverse with slow.
2')Target is left side upon and near luncher ==> do the turnning reverse with fast. then delay 20ms.
3)Target is just right upon luncher ==> do the turnning nothing with delay 0.5 secound.
if there is reading POS_v and POS_h different then do the turning routine else delay 50ms.
4) POS_v > POS_h +3 do the forward routine.
5) POS_h > POS_v +3 do the reverse routine.
else STOP.: shut the stepper motor down and then delay 0.5second.
beside these read the sensors and delays.
