3 If you have already built the Basic Driving and Steering Robot... These are the NEW parts you will need: These are the parts you will NOT use: Steps with asterisks (Step 100*:) are steps that vary from the Basic Driving and Steering Robot. Students should implement the changes denoted in these steps to make their basic robot into the maze robot. Page 3 of 22

14 Step 22*: Step 23 (Step 16)*: (Note the yellow rubber band this part may be hard to put on. It can be found in your kit.) Page 14 of 22

15 Step 24 (Step 17)*: Step 25*: (The 2x2 blocks displayed here represent the ends of Lego wires) Page 15 of 22

17 Step 28 (Step 21)*: Step 29*: Page 17 of 22

18 Step 30 (Step 22): Step 31 (Step 25): Page 18 of 22

20 Step 34*: Step 35*: Page 20 of 22

21 Step 36*: Attach the blue rubber band from the ½ bushing on the lever arm you built in steps to the dark grey peg on top of the touch sensors. The idea is to make the lever arm trigger the touch sensor when it is NOT touching a right wall. Step 37 (Step 26)*: Page 21 of 22

22 Step 38: Important Points: 1.) The block and peg in step 38 help prevent the robot from wandering too far right. If it interferes with the bump sensor, you may remove it. 2.) The orientation of the wire connections to the RCX and Motors MATTER. 3.) In step 34, you may move the piece that holds the 2 wheels in step 35 and the bushings on the rod to whatever distance you want. 4.) If you have already built the basic robot, you may find it easier to disassemble the old robot entirely to make sure you have all the pieces you need laying in front of you. Page 22 of 22
