Parts required
(1) robot chassis
(1) rubber grommet
(2) 1″ standoffs
(2) 1/4" pan-head screws
- Push the rubber grommet through the round hole in the chassis. A groove in the grommet fits over the edge of the metal, leaving a ring visible on both sides.
- Attach a 1-inch standoff to each outer-most hole in the front of the robot chassis. Use a 1/4-inch pan-head metal screw (these have a little dome on top with an x for the Philips-tip screwdriver). Insert the screw from underneath and twist the standoff on to it from the top.
