4. With the front of the chassis (the part with the
45' bend) pointing straight up, tape the back of the chassis (the
part with the 90' bend) to the work surface with masking tape or
Scotch tape. Don't use the tape that came with the robot kit
5. With the wheels sitting on the work surface, place the servos
against the chassis with the servo wires toward the back of the
robot chassis. Using a sharp tipped marker, mark where the forward
edge of the servos lines up with the chassis.
6. Remove the servos and untape the chassis from the work surface.
Mark a line lengthwise down the middle of the chassis. The chassis
is 80mm wide, so the mark is 40 mm from either edge.
7. Set the servo and wheel assembly on the chassis, lining up the
gap between the servos with the center line, and the front of the
servos with the line that you made in step 5. Check to make certain
that everything is centered and square, the tires do not stick out
past the back of the robot chassis, and the wheel nuts do not hit
the edge of the chassis..
8. If everything lines up, clean the servos with Windex or alcohol
and apply one piece of double stick tape to each of the servos.
9. Very carefully, attach the servos to the chassis, using the
marker lines for alignment. Remember, you only get one chance with
the tape. Take your time, this step is very important.
10. Attach the four 7/8 inch aluminum stand-offs to the chassis
with four 4-40 pan head screws. Do not tighten the screws yet, just
put them in loosely.
