Raspberry Pi Pi Cruiser User manual

Pi Cruiser Assembly Instructions
Tools needed
•A PH #1 screwdriver is required for most assembly. Included in the kit
•A small plier to hold the nuts
•A smaller screwdriver (PH #00) is required for attaching the ultrasonic sensor to the
mounting plate

Caster Wheel Assembly
•Identify the bottom plate
oAttach the two caster wheels to the bottom plate using eight M3 x 8 screws and
nuts. You may have to hold the nuts using a plier while using the screw driver.
oAttach two 20-mm hexagonal standoffs (female-female) for the line sensor array
using two M3 x 8 screws.

Line Sensor Assembly
oConnect five wires to the line sensor as shown. One for power, one for ground
and three are signal wires from each sensor.
oNotice the line sensor assembly can be mounted in one of the two sides (servo
wheel side or caster wheel side) depending upon your need.
oAttach the line sensor array using two screw M3 x 8 screws.
Route the wires through the slot.
Set aside this subassembly for now.

Servos
•Locate the chassis
oPosition a servo motor on the slot as shown. Notice how the servo wires are
oriented. Make sure servo motor tab is outside the chassis.
oSecure the servo using four M3 x 10 screws and nuts. To make assembly easy,
start with the lower screw and then go to the upper screw. Do not tighten the
screws until all the screws are in place and the servo is secured properly. Once all
the screws are in, tighten it. If the nuts spin, you may need to use a plier to hold
the nut as you tighten the screw.
oSecure the second servo exactly as the first servo. Do not flip the servo. Make
sure the wires are oriented in the same direction as the first servo.

oAttach the wheels to the servo using two small black screws that come with
servos.

Brackets
•Locate the two brackets. They are in a bag with rotating flanges.
oKeep the brackets on top of the chassis lining up with the holes and using two M3
x 8 screws secure the brackets

Install the Battery
•Place two weather strips or similar material in the slot designed for battery.
•Route the battery power wire through the slot (along with the servo wires). The battery
charger cable can be secured to the underside of the chassis.

•Place the battery in the compartment in a way that the battery wires come out of the open
side of the compartment and are close to the slot on the right. Refer to the photo.
•Close underside of the chassis using the plate. Make sure the eight holes on the plate are
aligned with the screw posts on the chassis. Place all the screws. Don’t tighten them
until all the screws are in place.

•Turn your chassis and place it on a flat surface. Your chassis supported by two servo
wheel and casters must be stand even and sturdy.

Electronics
•Mount the power board using three or four M3 x 8 screws on the top of the chassis as
shown. Be careful not to damage the electronic components while tightening the screws.
•Connect the servos to the Motor 1 ad Motor 2 ports.
•Connect battery power to the board
•Mount the break out board using four M3 x 8 screws on the top of the chassis as shown.
•Connect two female-female jumper wires to the power board
