Directions: Design Challenge: Either as individuals or in group of two, design build and test a vehicle that will travel around the raceway in the shortest amount of time. The teacher should decide whether the class will work individually or in groups of two. The class, or teacher, should determine the number of laps the vehicle needs to complete for timing. In utilizing this kit a student will: Work with tools to process materials and assemble a product. Work independently and cooperatively. Incorporate engineering design techniques. Better understand some of the principles of design. Work safely.
-
Draw some preliminary sketches of the racer and review with your teacher.
-
Select the best idea.
-
Draw a full size plan of the vehicle frame.
-
Cut, drill, fabricate and assemble the parts for the frame.
-
Mount the motor. gears, battery holder and switch on the frame so that power is transferred to the wheels.
-
Before soldering the wires test to make sure the wheels are turning in the proper direction, if not reverse the wires to the motor.
-
Test the powered frame on the track.
-
At this time consider adding bumpers and their design to facilitate moving the vehicle around the track.
-
Re-test the frame on the track (Did the bumpers help?)
-
Make any other modification deemed necessary to the frame to improve the operation of the vehicle.
-
Re-test the vehicle with the new modifications.
-
Repeat steps 11 and 12 until optimal results are achieved.
-
Draw a full size layout of the body.
-
Cut out the body from the layout.
-
Fold, glue and otherwise assemble the body.
-
Attach the body to the frame using thumb tacks or push pins (some modifications to the body and/or frame may be necessary).
-
Test again and make necessary adjustments.
-
Prepare vehicle for competition.
