Build Base Pt23. 4.

Attach Bottom pieces and Back Horizontal Reinforcers to Motors. Note: the Motors have been placed upside down in the picture!

The bottoms of the Motors are a light gray, if you see white on top then flip the Motors over.

Attach Pivot Wheel to Base

Flip the Base over so that the white tops of the Motor are showing!

The Pivot Wheel should attach to the bottom Back Horizontal Reinforcer

Upper wheel shows deeper impression. Lower wheel shows the shallower impression. This side should face the motors

Build Wheel and Axle Assemblies: Put#7 Axle through Large Wheel and then slide on bushing. Repeat for the other wheel. 2. Put the Wheel and Axle Assemblies through the center hole of the Motors. Note: some wheels have a deeper impression on one side than the other. The Shallower side should face TOWARDS the motors

. 1.

Attach Large Wheels (Drive Wheels)

Older wheels may need a bushing on both sides to hold the wheel on.

Build Side Assemblies Pt 23.

Attach 7-Hole Lift Arms to 3x5 L Shaped Bent Lift Arms. The 7-Hole Lift Arms should cover 4 holes of the 5-hole arm of the L Shaped Lift Arms. See upper left image. 4. Connect the 2x4 L Shaped Bent Lift Arms to the exposed ends of the 7Hole Lift Arms. The 7-Hole Lift Arm should cover 3 holes of the 4-hole arm of the L Shaped Lift Arm. Note: The completed Side Assemblies should be mirrored and form an“S” shape when viewed from the side. A backwards“S” may also work.

Attach Side Assemblies and EV31.

Attach Side Assemblies to the“Necks” of the Motors, as seen in the picture on the left. Note: Do not push Long Pins w/ Bushings fully in yet.

2.

Connect EV3 by lining up top most forward side holes with the top of the Side Assemblies and pushing in the Long Pins w/ Bushings.

Note: The screen of the EV3 should be over the back of the Motors and the ports labeled 1 through 4 should be facing the same direction as the Large Drive Wheels.13

Attach Wires to Motors and EV31. 2. 3.

Rotate the EV3 so you are looking at it from the back and can see ports A, B, C, and D Connect a wire to Port C of the EV3 and the left side motor. Connect a wire to Port B of the EV3 and the right side motor.14
