Caster Wheels

Step 1: Build Caster Brackets

Parts Needed:

  • REV-41-1303 – Bracket, Motion (2 per side, 4 total)

  • REV-41-1361 – Nut, Locking, M3 (2 per bracket, 4 per side, 8 total)

  • REV-41-1359 – Screw, Hex Cap, M3, 8mm (2 per bracket, 4 per side, 8 total)

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: Add Caster Brackets to Chassis

Parts Needed:

Caster Bracket Assemblies

Hint

  • Brackets must be installed 2 cm from the end of the extrusion, if used for competition, to fit within the sizing cube.

  • Ensure that the pair of brackets on the same extrusion are the same distance from the end of the extrusion or the wheels will not rotate properly.

Step 3: Add the Omni Wheels

Parts Needed:

  • REV-41-1327 – Shaft Collar (2 per side – 4 total)

  • REV-41-1326 – Bearing, Through Bore, Short (2 per side – 4 total)

  • REV-41-1323 – Spacer, 15mm (1 per side – 2 total)

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

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

  • REV-41-1190 – Wheel, Omni 90mm (1 per side – 2 total)

Hint

  • Order from the outside in: collar, omni wheel, 3mm spacer, bearing, bracket, 15mm spacer, bracket, bearing, collar.

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