Week 4 Objectives:

Objective A:    – Wire up a motor

Objective B:    – Wire a 2 AAA battery pack

Objective C:    – Assemble your robot body

materials needed:

Wire strippers
1x Gearbox motor
1x Male-male wire

Objective A: Motor Wiring

Attach leads to your motor for plugging into the breadboard.

1. Cut a male-male wire in half and strip about 15 mm of insulation from each side.
2. Carefully twist one half wire onto each of the copper tabs on your motor – the tabs are very delicate.

Be careful not to let the bare wires touch each other, as this can short out your motor and stop it from working.

Objective B: Battery Pack

Attach male leads to your battery pack for plugging into the breadboard.

1. Cut a male-male wire in half and strip about 15 mm of insulation from each side.
2. Cut off the soldered tips of your battery pack wires and strip them by the same amount.
3. Twist one half wire together with each battery pack wire.

1x Medium breadboard
2x Wheel
1x Popsicle stick
1x Coroplast square
1x Piece of rebar wire
1x Bead

Objective C: Robot Body

Construct the body of your robot.

1. Attach both wheels to the motor.
2. With hot glue, attach the popsicle stick and square of coroplast to the motor.
3. Peel off the paper backing from the breadboard and stick it down on top of the coroplast.
4. With hot glue, attach the battery pack to the underside of the coroplast.
Important: Make sure when gluing the battery pack that you can still open it and reach the ON/OFF switch.

Add a bead wheel to the front of your robot.

1. Slide the bead onto the stiff piece of rebar wire.
2. Bend the two sides of the wire up into a square ‘U’ shape.
3. With hot glue, attach the bead wheel to the front of your robot.
4. When the glue is completely dry, bend the bead wheel down so that it supports the weight of the robot.
