Take the two completed spring-loading mechanisms and attach
each one to a servo that has been modified for continuous rota-
tion. Use the servo screw that came with the servo horn to secure
the mechanism in place on the servo shaft, as shown in Figure
4.44.
Take one of the servos with the spring-loading mechanism
attached and secure it to a servo mount, using four 6/32-inch
1/2-inch machine screws, lock washers, and nuts. Attach the sec-
ond servo to the second servo mount, also using four 6/32-inch
1/2-inch machine screws, lock washers, and nuts, but note that
the servo is attached so that it mirrors the first one, as shown in
Figure 4.45.

Attach the servo mounts to the frog’s body using four 6/32-inch
