*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC UNDER FYP SUPERVISOR TEO SHIN JEN. DONE BY CHAN KAI CHI AND 2 ANONYMOUS.
Trigger gun when laser is blocked by intruding object.
Tilting is included for expandability but not used in this project.
Basic soldering and basic metal works
Things You Need:
Toy Gun(Any will do, preferably a semi-auto)
Continuous Rotation Servo Motor
Servo Arms and Wheels
Copper Strip Board
Light Dependent Resistor
Step 1: Building the Frame
Below are the dimensions we used:
4x 6”(inch) by 2”
1x 10.5” by 2.4”
1x 2.5” by 2.4”
1x 10” by 10”
1x 9” by 9”
Feet(6” by 2”):
Bend the 4 metal piece 90 degrees at the 2” mark and make screw holes(at least 2) at the shorter end.
Base(9” by 9”):
Make screw holes that match your feet’s at 4 corners of the metal piece to mount the feet and a hole in the center for the pivot(the hole size depend the bolt you’re using).
Gun Support(10.5” by 2.4”):
Bend the metal piece 90 degrees at the 2” mark and the 6.5” mark to form a deformed U. Make screw holes(at least 2) at shorter end and 4 holes at the other end to mount your servo.
Turning Panel(10” by 10”):
Make screw holes that match the gun support’s at one corner of the metal piece and one hole in the center for the pivot(should be slightly larger than the pivot but smaller than your ball bearings).
Servo Mount(2.5” by 2.4”):
Make a hole at one end to fit into the pivot and 4 holes at the other end to mount your servo.
