This Romi Chassis accessory offers a convenient way to expand your Romi robot vertically by adding new tiers. The expansion plate has the same diameter as the base plate, but we made it only a half circle to give you more expansion options. For example, when used as part of the Romi robot arm kit, it supports the arm in the back while leaving the front half of the Romi open. For a full-sized expansion platform, just combine two expansion plates. A mixture of mounting holes and slots give you the flexibility to mount components in a variety of orientations almost anywhere on the plate.

This expansion plate for the Romi chassis is made from black ABS.
