assembly steps
1. attach (2) 13cm pipes to 90 degree bend   (make 2 of this kind )
and cut a small opening to put metal brackets .






2. attach 10cm pipe to 18cm pipe using 45degree bend ... next attach the another 45 degree bend to other side of 10cm pipe and attach 5cm pipe to that and attach the cap. cut a small opening in 18cm pipe to place the brackets . ( make 2 of this kind )




3. attach 9cm pipe to 15cm pipe using 90degree bend . again attach 9cm pipe to 15cm pipe using 90 degree bend. and attach both the frames  ( THIS SHOULD LOOK LIKE A RECTANGLE )





4. drill 2 holes at the end of the both the caps 9 which we made in step 2 ) 
5. drill 1 hole in both 13cm frames (mentioned in step 1)
 
6. attach both step 1s and 2s frames using the metal sheet by fixing screws in the holes we drilled





7. now drill 2 holes in (rectangle from ) on 9cm pipe on both side





8. now drill 2hole in mane frame on the center 10cm pipe and attach these (main frame and rectangle frame together ) screws .






 9. now attach motors to the brackets and complete the circuit and upload the code
