Build the Boe-Bot Robot

Follow the steps below to build your Boe-Bot robot chassis.

Step 1: Mount the Topside Hardware

(1) robot chassis
(4) 1″ standoffs
(4) pan-head screws, 1/4″ 4-40
(1) rubber grommet, 13/32″

Insert the 13/32″ rubber grommet into the hole in the center of the chassis. The groove on the edge of the grommet sits over the metal edge of the hole.
Use the 1/4″ screws to attach the standoffs to the top of the chassis near each corner, as shown.

(2) Parallax continuous rotation servos.

Use a Phillips screwdriver to remove the screws that hold the servo control horns on the output shafts.
Pull each horn upwards and off the servo output shaft.
Save the little screws; you will need them again soon.

(1) Boe-Bot Chassis, partially assembled.
(2) Parallax continuous rotation servos
(8) pan Head Screws, 3/8″ 4-40
(8) nuts, 4-40
masking tape
pen

Slide the servos into the chassis. Look at the little arrows: the servo’s mounting tabs set outside, and the little holes in the servo case are facing the triangle end of the chassis.
Attach the servos to the chassis using the Phillips screws and nuts.
Use pieces of masking tape to label the servos left (L) and right (R), as shown.

(2) flat-head Phillips screws, 3/8″ 4-40
(2) nuts, 4-40
(1) 4-cell battery pack with 2.1 mm center-positive plug

Insert the battery pack inside the chassis positioned as shown in the picture below.
Insert flat-head screws from inside the battery pack, and secure them in place with the 4-40 nuts and tighten securely.
Add batteries to the battery pack.

(1) 1/16″ cotter pin
(1) tail wheel ball
(2) rubber band tires
(2) plastic machined wheels
(2) screws saved when removing the servo horns

Pull the servo cords and battery pack cord up through the grommet hole in the center of the chassis.
Line up the hole in the tail wheel with the holes in the tail portion of the chassis.
Run the cotter pin through all three holes (chassis left, tail wheel, chassis right).
Bend the ends of the cotter pin apart so that it can’t slide back out of the hole.
Press each plastic wheel onto a servo output shaft until it sinks into the wheel’s recess, then secure with the saved servo screws.
Stretch each rubber band tire and seat it on the outer edge of each wheel.

The brain of your robot is a tiny computer called the BASIC Stamp microcontroller.

The BASIC Stamp plugs into the Board of Education development board. It lets you easily connect the BASIC Stamp to:

Mount the Board of Education to the Boe-Bot’s standoffs as shown, using (4) 4-40 pan head screws.

Place the board on top of the standoffs, so that the white breadboard is close to the large wheels.
Use the screws to attach the board to the standoffs at each corner.
