Looks like you got lost!

Now that we are familiar with the Pick and Place robots, let's dive into the assembly of the same. We are starting with the Horizontal Robot.

1. First, detach the Castor Wheel from the Quarky Robot by removing the Bolt.
2. Place the Motors on the top of the B1 Plate using the Motor Mount Bracket. Fasten it using M2 Bolt and M2 Nut that you get with Motors. Note: You have to make sure the Motor is appropriately mounted. Note: Make sure the B1 is written on the opposite side of the Motor.
3. Now attach the Wheels to the Motors.
4. After that, attach the Wheel sub-assembly (with wheels) in front of the Robot. Fasten it using M2.5 Nuts and Bolts.
5. The motor connection is similar to the Four Wheel Drive Robot. Connect the two left motors and then connect the wire to the Board. Do the same for the right motors.
6. Fasten one Spacer on the B5 Plate with an M3 Bolt of 8mm Length as shown below.
7. Fasten another Spacer on the B5 Plate with an M3 Bolt of 8mm Length as shown below.
8. Fasten another Spacer on the B5 Plate with an M3 Bolt of 8mm Length as shown below. The spacer will be on the opposite side of the other spacers.
9. Fasten another Spacer on the top of the other B5 Plate with an M3 Bolt of 8mm Length.
10. Align both the B5 Plates on Spacers as shown below and Fasten them using two M3 Bolt of 8mm Length.
11. Insert the Servo Motors in the B5 Plate and snap it tight. You have to make sure that the wire of the servo motor is coming from the inside. The Servo Motor shaft aligns with the '+' mark on the B5 Plate.
12. Snap the A5 Plates on the Quarky Robot as shown below.
13. Connect the Left Servo Motor to the Servo 1 and the Right Servo Motor to the Servo 2. Note: The position of ultrasonic head is only for illustration purpose here. The below image only shows how to connect servo motor pins, the positioning of ultrasonic head will be different.
14. Open PictoBlox and set the Servo Motor angle to 90 degrees. The servo head should get aligned properly.
15. Lock the B5 Plate by snapping the B6 Link.
16. For the next sub-assembly, Attach the 2 Spacers to the B12 Link with the M3 Bolt of 8mm Length.
17. Now attach 2 more Spacers to the same B12 Link with the M3 Bolt of 8mm Length.
18. Now attach 2 more Spacers to the other B12 Link with the M3 Bolt of 8mm Length on the opposite side.
19. Align two B12 Links and fasten with the M3 Bolt of 8mm Length. We will call this subassembly - Hook Assembly.
20. Align & attach the B10 Link to the Spacers of the Hook Assembly with the M3 Bolt of 12mm Length and on the Spacer of the B5 Plate with the M3 Bolt of 12mm Length.
21. Snap the B11 Link on the Servo Motor Shaft. On the other side of the B11 Link attach it to Hook Assembly with the M3 Bolt of 12mm Length.
22. Align & attach the other B10 Link to the Spacers of the Hook Assembly with the M3 Bolt of 12mm Length and on the Spacer of the B5 Plate with the M3 Bolt of 12mm Length.
23. Snap the other B11 Link on the Servo Motor Shaft. On the other side of the B11 Link attach it to Hook Assembly with the M3 Bolt of 12mm Length.

The assembly is complete. We will continue to program the robot in the next lesson.
