Build the Line Follower Bot

1. Bolt two short L-frames to each blueboard. The ends of the L-frames that are sticking up in the air should be facing the outer edge of the blueboard. Pay attention to their placement!
2. Place the two blueboards next to each other and attach them with a 7-hole metal frame. 3 holes of the metal frame should be on each blueboard. Bolt a short standoff to the hole that’s in the middle of the two blueboards.
3. Bolt a long L-frame to each blueboard next to the 7-hole metal frame.
4. Just like step 2, bolt another 7-hole metal frame to the two blueboards and attach a short standoff in the middle. Make sure you use long bolts this time!
5. Attach four long bolts to the inner corners of the blueboards. Pay attention to their placement! Next, flip everything over.
6. Attach another blueboard using the long bolts you just attached. Flip everything back over so you see the short standoffs and the short L-frames sticking up.

1. Bolt the DC motors to the short L-frames.
2. Line the holes in the battery box up with the short standoffs and then bolt into place.

1. Attach the wheels to the motors using small black screws. The wheels will also stay attached without the screws!
2. Use two long bolts to attach the Smart Inventor Board to the front of Line Follower Bot. Pay attention to the placement of the bolts!

To wire your Line Follower Bot, place it so the Smart Inventor Board is facing you.

• The motor on your right is M1.
• The motor on your left is M2.
• Attach the motors to their respective spots on the Smart Inventor Board (M1, M2, M3, and M4 are all marked).
• Make sure that the red wires are the in the negative position (facing the inside) and that the black wires are in the positive position (facing the outside)!
