to 90 degrees. (From here on out, we will refer to

our motor mounted on the left side of the base as

motor 2 and the motor mounted on the right side

of the base as motor 3.)

STEP 7: ATTACHING THE LINK 2 COMPONENTS

Once motors 2 and 3 have been successfully set

to 90 degrees, it’s time to begin assembling the

components that will make up the second link of

our system. The first piece you will need, pictur ...
