Pre Step: Peel Your Plastic

Some of your plastic pieces will have paper masking on one or both sides. Peel the masking paper off before getting started.

There also may be some dust on your parts. This is from the laser cutting manufacturing process. It is harmless and can be cleaned up by wiping with a rag or being washed with water.

Each plastic piece will have 2 sides - a matte side and a glossy side. When you're assembling your kit, the matte side should point up while the glossy side should point down.

  • Mount the Servo to the Side Bracket using 4 M2*5 bolts and 4 M2 Nuts. You can also use M2*6 or M2*8 bolts.
  • Place the 4 M2 Nuts into the 4 side slots on the Servo
  • Mount the Servo onto the side frame with the Nut Holder in between them.
  • Make sure that the servo orientation is as shown in the picture.
  • Screw the bolts in half-way (Do not fully tighten the bolts or you will lock the Nut-Holder in Place)
  • Remove the Nut-Holder, then tighten the bolts in all the way.

Step 4: Attach the Wheel Plates

  • Fit the Rubber Tire over the two Wheel Plates

Step 6: Mounting the Wheel Kits

  • There are two ways to mount your Servo Wheel Kits: Topside Mounted and Underside Mounted. Pick the way that works best for your project.
  • The 'Left Configuration' and 'Right Configuration' pictures refer to the Topside Mount. For the underside mount the left/right positions will be reversed.
  • Underside mount is recommended. It allows you to mount the battery packs under the robot chassis where it is easy to change the batteries without disassembling the robot.
