T5x40 torx screwdriver (provided)
no. 3 hex-head key (metric; provided)
hex-head wrench no. 8
main electronics box
camera shield gasket
4x self-tapping torx screw (smallest in the kit)
T5x40 torx screwdriver (included)
Put the camera shield gasket on the shield. Mind the gasket 'tooth'.
Position the shield with pins to correspond with main electronics box holes.
Push the camera cover all the way to the cutout.
Tighten the self-tapping torx screws.
step 1 assembly
fisheye camera (may come with IR lights mounted)
plastic camera mount
4x 2.2x6.5 self-tapping screws (cross-headed)
Detach IR lights from the camera.
Align the camera with the camera mount holes and screw 2x 2.2x6.5 screws (or 3x depending on the kit). Mind the side of the mount.
Assemble the camera mount to the main electronics box using two corresponding standoffs and 2x 2.2x6.5 self-tapping screws.
step 2 assembly
power cable (3pin socket with barrel plug and green cable soldered)
miniUSB socket with USB-A connector
Unscrew power socket nut.
Push the nut through barrel plug.
Route barrel plug and then green cable through a corresponding cutout in main electronics box wall.
Push the socket in place. Mind how the socket is positioned - white dot.
Thread the socket nut back through the barrel plug and green cable. Tighten the nut (tightening by hand is enough).
Disassemble miniUSB socket nut.
Put the socket in a corresponding MEB floor cutout.
Tighten the socket nut. You can do it by hand.
step 3 assembly
antenna cable with o-ring, nut and toothed washer (put o-ring on the socket if needed)
flat wrench no. 8
Put some vaseline on the socket o-ring.
Place the socket in a dedicated cutout in MEB floor. Rotate it to meet the cutout shape. Don't push it - we'll do it by tightening the socket nut.
Put the toothed washer and socket nut on the opposite side (external wall) and tighten it using no. 8 wrench. Make sure the socket pulls equally in the cutout (looking from internal side).
step 4 assembly
4x rubber bushing
Put vaseline grease on the main electronics box sidewalls holes.
Press the bushings by hand.
step 5 assembly
4x wheel cable (with goldpin socket)
Put some vaseline on the cable ends.
Push the wire through rubber bushing from inside to outside of the main electronics box.
Pull the wire keeping the end of black isolation still inside the box.
Do the same with the rest of wires.
Secure the ends of black isolation with zip-ties. This way the cable won't be pulled out during the rest of assembly process.
step 6 assembly
4x m4x5 distances
wrench no. 7
loctite glue (provided)
First add a little drop of Loctite glue to each thread in external side of MEB floor. Then tighten the distances.
step 7 assembly
4x m2.5x18 plastic distances
wide camera tape (white; from camera box)
microSD card extender (older version only)
Connect microSD extender to RaspberryPi microSD port.
Put RaspberryPi board in the main electronics box. Align to corresponding brass inserts and secure with threaded m2.5 distances. Tighten them by hand (don't use any tool as they are easy to break). Keep the microSD extender tape routed outside of MEB.
Prepare the white camera tape. Connect it to RaspberryPi port named 'camera'. Make sure there's a connection between the tape and the port pins.
Connect the tape to camera port. Route the tape so it won't come in a way when mounting next components.
Take USB-A plug and twist it to connect to the nearest RaspberryPi USB port.
Put microSD card in the card extender. We'll flash software to the card in Task 9.
Core2-ROS electronics board
4x m2.5x18 plastic distance
Core2-ROS is connected to RaspberryPi using GPIO. Make sure the pins of both boards mate clearly.
Put Core2-ROS in the main electronics box. Connect Core2-ROS pins to RaspberryPi GPIO.
Secure the boards together using 4x m2.5x18 plastic distances. Tighten them by hand.
Connect power plug to the board.
Connect green 1-pin cable to 'p1' pin of the board (as seen in the photo below).
MEB has each of the wheel cables named by the place where it's routed through external wall.
Connect the wheel cables to corresponding hMotor ports of Core2-ROS. Make sure you connect right 'letters' to the right ports. As well the 6-ping sockets should be positioned the way white cables mate with EncB and red cables with MotA labels of motor ports.
step 9 assembly
Wifi modem board
Wifi model USB cable
2x m2.2x6.5 self-tapping screws
4x m2.5 plastic screws
plastic modem adapter
Screw the modem to the modem adapter using 2x 2.2x6.5 self-tapping screws and cross-headed screwdriver. Make sure you position it as shown in the photo below.
Attach the modem adapter to plastic distances using 4x m2.5 plastic screws and cross-headed screwdriver. Position it as shown as well.
Connect Wifi modem USB cable to the modem and then to the most convenient USB port in RaspberryPi.
Plug the antenna cable to the modem socket and secure the cable with zip-ties.
Push microSD card extender between Core2-ROS board and Wifi modem adapter to keep it in place.
step 10 assembly
cyanoacrylate glue (optionally)
Push and route the seal in MEB groove all the way on the box outline.
Overlap the seal endings and cut it with 5 mm excess.
step 11 assembly
plastic box lid
4x m4x12 screws
hex-head key no. 3
Put the lid on top of the box assembly. Make sure the box rubber seal is pressed equally and the endings don't come out the outline.
Secure the lid using 4x m4x12 screws and no. 3 key.
Depending on the Kit setup you'll be provided with either 1x6 goldpin plugs or 2x6 goldpin. In case of 2x6 connect mating pair of wheels into one plug.
Find the proper wheel name on Core2ROS driver to connect. The connectors are located in left bottom of the image below.
