Line Follower Robot Year 9 Electronics V1.1

Step 1: Knowing The Chassis Chassis has been laser cut from 4mm fluted correx board Main P.C.B. Sensor P.C.B. Motor Brackets. Uniball Castor.

Step 2: Preparing the Motor Brackets Both brackets need to be strip heated A 90 o bend formed where the red line is V IMPORTANT THIS IS DONE ACCURATLEY! Bend should push the lowermost plastic underneath and away from the lettering side

Step 3: Bolt Brackets To chassis Use M3 nuts & bolts Cut to length using a junior hacksaw and metalwork vice Secure using a flat headed screwdriver and log nosed pliers chassis bracket = bolt locations

Step 4: Bolt Motors to Brackets Line the motor up on the inside of the bracket Push the square motor locator pip & axle into the bracket cut-out Attach the motor to the bracket using M3 nuts & bolts Push bolts through from outside of bracket (wheel side) and nut on the inside Locator pip. axle. Bolt holes

Step 5: Attach Wheels Wheels push on gently to the motor axle

Step 6: Add uni-ball castor Attach using M3 nuts & bolts Push bolt through from the underside of the chassis and nut on the top side = bolt locations

Step 7: Add sensor PCB Use nylon spacers between the chassis and PCB. Use M3 nuts & bolts Make sure the header pins on the sensor PCB push cleanly through the square cutout in the chassis = bolt locations

Step 8: Add main PCB Use nylon spacers between the chassis and PCB. Use M3 nuts & bolts = bolt locations

Step 9: Quality Checking What have you done to check the quality of your build? How have you checked the quality of your build? Write a set of bullet points on what you have checked how you have done it What equipment you have used ** submit via ShowbieShowbie ** Remember: your eyes & the process of visual inspection are one of the best tools you have for checking build quality, but what have you checked?
