Summary A friend challenged me to make him a DJ Roomba as seen in the TV show "Parks and Recreation", so I gladly took on the project! You can see details about the assembly in this video or you can check out the whole design process in this playlist! My design considerations for the mount were:

• Removable: Roombas and the like are not cheap products, so I didn't want to glue or screw into it.
• Adaptable: There is a variety of vacuum robots out there, so any of them should make a good DJ Roomba! You can easily edit the clamps to your robot's height.
• Unobstructive: The brace should not interfere with the normal operation of the robot. All sensors, buttons, and ports should be accessible.
• Versatile: Vacuum robots can be great platforms for a variety of projects! The brace should allow anyone to build any type of robot they can imagine!

To assemble DJ Roomba brace you'll need some hardware:

• 1/4"-20 x 1/2" screw (x1)
• 1/4"-20 nuts (x3)
• 1/4"-20 lock-nuts (x3)
• 1/4"-20 x 6" threaded rod (x3)
• washers (x3)
• glue

Additionally, you could print a figurehead for your Roomba's "prow"! all you need is to do add a socket for a 1/4"-20 nut in your favorite model and screw it in! You can look at my Harambe Head, for example.
