If you are following this tutorial and using the Wheel Encoder Kit, you will want 2x 4" zip-ties to connect the wheel encoder to the motors included in the RedBot kit.

Suggested Reading

To better understand the RedBot and all of its parts, we recommend checking out the Getting Started with the RedBot tutorial.

**Wheel Encoder**

Read on if you are using the Wheel Encoder Kit. If not, skip to the next section.

The Wheel Encoder Kit is a simple add-on to any wheeled robot that can help measure the speed or distance the chassis travels. For the RedBot, we found that it is easier to use this wheel encoder.

Locate the Following:

2x Motor 2x 4" Zip-Tie 1x Wheel Encoder Kit
Motor Zip-ties Female Servo Headers

Adding the Wheel Encoder to Motors

First, you will want to grab a 4" zip-tie (a smaller zip-tie will work as well). Push the zip-ties inside the opening between the clear plastic and the motor. Make sure the zip-tie is going through the opening that isn't on the same side as the black and red wires soldered to the motor.

Zip ties through plastic

Next, slightly close the zip-tie. Make sure not to fully tighten the zip-tie yet.

Slightly close zip tie

Grab the hall effect sensors, terminated with 150mm cables and a 3-pin female servo header, from the Wheel Encoder Kit. Bend the hall effect sensor side downward at a 90 degree angle, as shown in the photo below.

Bent wire

Bend the hall effect sensors cable again, so it is laying horizontal on itself. Bending the cable again makes this setup sturdier and the hall effect sensor less likely to move around.

Second bend on encoder wires

Place the bent hall effect sensors cable through the zip-tie loop created earlier. You will want to line up and point the hall effect sensor to the middle of the shaft of motor.

PLacement of the encoder wire

Tighten the zip-tie firmly. Make sure the hall effect sensor is still pointing inward to the shaft of the motor. Using flush cutters, cut the zip-tie's extra end hanging out.

Cut zip tie

Add the neodymium 8-pole magnet with the rubber hub to the shaft of motor. The hall effect sensor should be horizontal.

Encoder top

Go ahead and do the same the wheel encoder setup to the other motor.

Second motor is the same

Double check the hall effect sensors are nice and lined up between the motor and magnet with the rubber hub. Also be sure that it is pointed inward toward the shaft of the motor.

Motors

In this section, you will be placing the two motors on the bottom side of the bottom chassis piece.

Locate the Following:

1x Bottom Chassis Piece 4x Motor Holder 2x Motor
Bottom Chassis Piece Motor Holder Motor
2x 4-40 x 1 1/4" Flat Head Screw 2x 4-40 Hex Nut
Screw - Flat Head M3 Nut

Please note: ** Pay close attention to which screws you are using. There are two different screws in the RedBot Kit. (30x** of the 4-40 x 1/4" Phillips screw and 4x of the 4-40 x 1 1/4" flat head screw).

Adding the RedBot Sensor - Mechanical Bumper? You will have 3x of the 4-40 x ⅜" Phillips screw.

Adding the Motors

Find the correct location on the bottom chassis piece.

Bottom Motor Graphic

Place one of the motor holders through the chassis at that location.

Motor holder in the correct spot

Push the motor holder all the way down.

Motor holder placed down

Place the first motor on the bottom side of the chassis piece. It is important to make sure the side of the motor with the wheel encoder is pointing to the back side of the RedBot bottom chassis piece. To tell the difference between the back and front of the chassis, the chassis's back is flat and the chassis's front is curved. (The back of the chassis is where the metal ball caster will go. You will be putting that on later.)

Line up the two motor holes with the two motor holder holes. Make sure that the red wire soldered onto the motor is on top and away from the chassis piece.

Motor placed on board

Place the 4-40 x 1 1/4" flat head screw through the top motor holder and motor holes.

Screw going through top hole

Using a screwdriver and 4-40 hex nut, tighten the screw.

Using screwdriver to tighten screw

Double check the side of the motor with the wheel encoder is pointing to the back side of the RedBot bottom chassis piece.

Following the same steps as the first motor, add the second motor holder on the other side.

Second motor screwed in

Place the motor's black and red wires through the bottom chassis so the wires come through to the top side of the chassis.

Motor jumper wires through chassis holes holes

Now, push the wheel encoder's wires through to the top side of the chassis. It is best to push through the chassis opening that is closest to the motor, as shown below.

Encoder jumper wires though chassis holes

As you can see, the wires are now through the top of the chassis piece. It is highly recommended to have the wires push through the same chassis openings as shown below. This way it is easier to connect to the RedBot Mainboard toward the end.

Please note: ** Pay close attention to which screws you are using. There are two different screws in the RedBot Kit. (30x** of the 4-40 x 1/4" Phillips screws and 4x of the 4-40 x 1 1/4" flat head screws).

Adding the RedBot Sensor - Mechanical Bumper? You will have 3x of the 4-40 x ⅜" Phillips screws.

There are also different standoffs in the RedBot Kit and add-ons. The RedBot Kit comes with 7x 4-40 x 1" metal standoffs, 4x 4-40 x ⅜" metal standoffs, and 3x 4-40 x 1 1/2" metal hex standoffs.

Adding the RedBot Sensor - Mechanical Bumper? You will have 3x of the 4-40 x 3/4" nylon standoffs.

Adding the Metal Ball Caster

Place a 4-40 x 1/4" Phillips screw through one of the ball caster's holes. The screw's head should be on the same side as the ball caster's metal ball. Then, screw in one of the 4-40 x 1" metal standoffs to the metal ball caster.

Screw through ball caster

Using a 4-40 x 1/4" Phillips screw, screw on the second 4-40 x 1" metal standoff on the other side of the ball caster.

Second stand off in

Locate the two positions on the chassis piece where you will be screwing down the metal ball caster.

Bottom chassis graphic for ball caster

Now, you can use two 4-40 x 1/4" Phillips screws to tighten down the metal ball caster to the bottom side of the chassis piece. The metal ball caster should be on the same chassis side as the motors.

There are also different standoffs in the RedBot Kit and add-ons. The RedBot Kit comes with 7x 4-40 x 1" metal standoffs, 4x 4-40 x ⅜" metal standoff,s and 3x 4-40 x 1 1/2" metal hex standoff.s

Adding the RedBot Sensor - Mechanical Bumper? You will have 3x of the 4-40 x 3/4" nylon standoffs.

Adding the RedBot Line Followers

Place a 4-40 x 1/4" Phillips screw through one of the line followers. Then, twist on the 4-40 x 1 1/2" metal hex standoff. Make sure to tighten the standoff on the line follower's header side. The top of the screw should be on the same side as the line follower's sensor.

Screwing stand off to line follower

Do this for the other two line followers.

All three line followers with stand offs

Locate three spots on the chassis where you will be adding the line followers.

Line follower locations

Place a 4-40 1/4" Phillips screw through the top side of the chassis piece. Tighten down the 4-40 x 1 1/2" metal hex standoff with a line follower into the bottom chassis piece. The line follower should be on the bottom side of the chassis piece. The headers on the line follower should be pointing in toward the chassis. Do this for the other two line followers.

All line followers in correct chassis locations

Adding Jumper Wires

Time to add some jumper wires! You will need to connect a jumper wire to each female header pin on the line followers. There will be nine total jumper wires.

You do not need to have the same color jumper wires as this assembly guide. However, following along with the jumper wire colors in this assembly guide may be helpful if this is your first time assembling the RedBot. See below if you are following along with the jumper wire colors to help lessen confusion when hooking up the RedBot Mainboard later in the guide.

Here is the view from the bottom side:

Added Jumper Wires

Take the jumper wires and place them through the chassis openings. The jumper wires should be sticking out on the top side of the chassis. We recommend that each group of three jumper wires, for each line follower, goes in a different chassis opening as shown below. This helps keep track of the different jumper wires when connecting to the RedBot Mainboard later.

**RedBot Sensor - Mechanical Bumpers**

Read on if you are using the RedBot Sensor - Mechanical Bumpers. If not, skip to the next section.

You will need to prepare the music wire by bending the wire itself. Then, you will add standoffs and screws to your mechanical bumpers, followed by adding the mechanical bumpers to the RedBot chassis.

Locate the Following:

6x 4-40 x 3/8" Phillips screw 2x 4-40 x 3/4" Nylon Standoff 2x 4-40 Hex Nut

Prepare the RedBot Sensor - Mechanical Bumpers

Screw a 4-40 x ⅜" Phillips screw and 4-40 hex nut to one of the two large mechanical bumper holes.

Screw and nut in one side of bumper

Time to bend the whisker! It is easy to bend the whisker with needle nose pliers. However, there is a trick to bend the whisker using the mechanical bumper PCB itself. First, stick one of the whiskers through one of the smaller side holes. It only needs to stick out a little bit.

wire through hole

Bend the whisker 90 degrees.

Benting the wire

Bend the whisker 90 degrees again.

Benting the wire even more

Now that the whisker is bent, take the wire out of the PCB hole. Add a 4-40 x ⅜" Phillips Screw from the bottom and loop the bent whisker around the screw. It is very important that you do not let the whisker touch the other side's 4-40 hex nut and 4-40 x ⅜" Phillips screw, since that is what triggers the sensor. Leave a little space between the wire and other side's nut.

Wire looped around screw

Twist a 4-40 x 3/4" nylon standoff on top of the screw to secure the wire.

Adding standoff

Double check that the wire does not touch the other side's 4-40 hex nut and 4-40 x ⅜" Phillips screw.

Do not let wire touch

Do this for the other mechanical bumper. Take note of which side your 4-40 x 3/4" nylon standoff is on for the first mechanical bumper. Do the opposite for the other bumper. Double check that there is one mechanical bumper that has a 4-40 x 3/4" nylon standoff on the right side of the "RedBot Bumper" silkscreen and one that has a 4-40 x 3/4" nylon standoff on the left side.

Do the opposite for the other music bumper

Adding RedBot Sensor - Mechanical Bumpers

Locate the two positions on the top chassis piece.

Top chassis locations for Mechanical Bumpers

Using two 4-40 x 1/4" Phillips screws, tighten down the mechanical bumpers with the two wires pointing in opposite directions on the bottom side of the top chassis piece. The mechanical bumpers' header pins should be pointing toward the chassis piece.
