  2. TASK DESCRIPTION • The objective of this task is to build a simple RCX one-motor car using a cross-gear system. • To prepare for this task, you may practice it as much as you need to, but you will be required to pass it off within 15 minutes whenever you decide you are ready. • The basic instructions are shown on the next few slides…practice this process until you have mastered it!

  3. Step 1 We’ll start by using the two side holes of the RCX brick with 4 special 1 ½ connectors. The “1/2” parts of the connectors fit into the RCX brick side holes.

  4. Step 2 Next find two size sixteen “holey” beams and connect them to each side of the brick aligned as shown.

  5. Step 3 Using four more size sixteen beams, connect two together and then to the existing beams on both sides.

  6. Step 4 To build the single motor assembly, find the plates shown…1 2X10, 2 2X6, and 2 2X4. Attach them as you see in the pictures.

  7. Step 6 Now attach the motor assembly to the brick as shown here.

  8. Step 7 To reinforce on the top side, first attach a 2X10 plate across the top of the motor to the two side beams.

  9. Step 8 Then put another piece on top of that with two more cross pieces attaching to the RCX brick.

  10. Step 9 Now its time for the cross gear assembly. Find the parts shown on the right…a 24-tooth crown gear, a 24-tooth stud gear, a size 12 axle, four bushings, and two wheels.

  11. Step 10 Attach the crown gear to the motor, and then insert the axle through the end hole of the middle beam and attach two bushings.

  12. Step 11 Push the axle all the way through, attaching the 24-tooth stud gear and the other two bushings as shown.

  13. Step 12 Now attach the wheels and a skid plate, similar to the one used for the two-motor car, but a bit taller. This extra height on the skid plate is necessary to provide clearance for the supporting brace plates on the bottom.

  14. Option If a lower profile is desired, the bottom braces can be removed and the skid plate reduced, as shown here.

  15. Time to practice! Practice this construction until you have mastered it and can accomplish it in 15 minutes or less. When you are ready, tell a mentor so you can pass it off. Good luck!
