                                    the charger and plugging the charger into an electrical socket. This will ensure
                                    that the batteries are ready for you when the robot is complete.

                         Building the Frame
                                    Start by finding the IR rangers, and the parts to connect the ranger to the alu-
                                    minum frame. For each ranger you will need two 5/8-inch screws, two nylon
                                    washers, two nylon spacers, two lock washers, and two nuts. These parts will
                                    be in bag one of the kit. Attach one ranger to each aluminum frame piece. Start
                                    by inserting both screws through the frame, then adding the washers and
                                    spacers. Place the sensor onto the screws and fasten it with the lock washers
                                    and nuts.















                                      Now you will attach the three frame pieces together to make a single frame.
                                    Notice that each piece has a long arm and a short arm. When the pieces are ori-
                                    ented correctly, the long arm on one piece will line up with the short arm on an
                                    adjacent piece. Align the holes in each arm, and connect the pieces using a
                                    screw, washer, and a nut from bag two of the kit. Tighten the nuts just enough
                                    to hold everything together; we will tighten them completely in a later step.















                                      The next step is to attach the servos to the frame. Each of the three servos
                                    will be attached to the frame through the rectangular hole that is on each side
                                    of the frame where the frame pieces connect. You can see that the hole is offset
                                    from the center of the side; when the servo is placed correctly in the hole, the
