Description

Bumper Cage Kit for Balboa 32U4 Balancing Robot.

Overview

Protect your Balboa robot from falls with this bumper cage kit, which includes:

  • four bumper skids
  • four bumper cage cross bars
  • two bumper skid spacers
  • twelve 12 mm M3 screws and nuts

The pieces for this kit are already included in the Balboa 32U4 Robot Kit, but we have made them available separately for those who need replacements or want a set to use with the Balboa Chassis Kit, which does not include the bumper cage. The bumper cage skids mount to the side of the Balboa chassis or stability conversion add-on and can be arranged in a wide variety of positions, configurations, and orientations, enabling a wide variety potential uses. The primary purpose of the bumper kit is to absorb an impact before your electronics do, which is especially important for balancing applications, where hard falls can be a frequent occurrence. In addition to this, they can be positioned to prop your robot at just the right angle for it to be able to kick itself back up to vertical, or you can just use them as skids for your Balboa to drive around on.

The bumper cage skids and cross bars include a number of holes and slots sized to work with #4 and M3 screws, which gives you a lot of flexibility in how you can put them together and what you can mount to them (see the bumper cage kit dimension diagram (152k pdf) for more information). The following example shows them holding a QTR-8RC reflectance sensor array in front of the Balboa 32U4 Robot with the Stability Conversion accessory:
