Drive Assemblies and Frame

Step 1: Build Drive Brackets

Parts Needed

• REV-41-1303 – Bracket, Motion (4)

• REV-41-1361 – Nut, Locking, M3 (8)

• REV-41-1359 – Screw, Hex Cap, M3, 8mm (8)

Hint

• Screw the nuts onto the screws just until it’s difficult to turn them; just so that the nuts don’t fall off. The screw heads will need to slide along the center of an extrusion in a later step.

Step 2: Build Motor Assemblies

Parts Needed:

• REV-41-1300 – Core Hex Motor w/cables (2; do not plug cables into the motors yet)

• Drive Bracket Assemblies (1 per motor, 2 total – use only two of the assemblies from step 1)

• REV-41-1359 – Screw, Hex Cap, M3, 8mm (3 per motor, 6 total)

Note

• Make sure that the brackets are facing the correct direction; the alignment ribs should be on the side away from the motor.

• Note that motor directions are reversed – the power plug of the motor pictured on the left is on the bottom; the plug of the motor on the right is on the top.

Step 3: Build the Right and Left Rail

Parts Needed:

• REV-41-1432 – Extrusion, 420mm, 90-90 degree (1 per side, 2 total)

• Motor Assemblies (1 per side, 2 total – from step 2)

• Drive Bracket assemblies (1 per side, 2 total –the two remaining from step 1)

• REV-41-1327 – Shaft Collar (1 per side, 2 total)

• REV-41-1326 – Bearing, Through Bore, Short (1 per side, 2 total)

• REV-41-1347 – Shaft, 5mm Hex, 75mm (1 per side, 2 total)

Hint

• Slide the head of the screws down the center of the extrusions.

• The brackets should be flush with the end of the extrusions.

• bracket, bearing, spacer, collar, two spacers, bracket with attached motor. (Order from the outside in.)

Step 4: Add Drive Wheels

Parts Needed:

Rail Assemblies (1 per side, 2 total – from step 3)

• REV-41-1354 – Wheel, Traction 90mm (1 per side, 2 total)

• REV-41-1327 – Shaft Collar (1 per side, 2 total)

• REV-41-1324 – Spacer, 3mm (1 per side, 2 total)

Hint

• Order from the outside in. (Collar, wheel, spacer, rail assembly.)

• Make sure that the wheels do not rub the nuts. If they do, then revisit previous steps to make sure the construction is accurate.

• Adjust axle length, so it is flush with the collar.
