Bucki is not the first iteration of a 18 lb Bent Bar Shuffler. Bucki is unfortunately the first iteration of the 12 lb pneumatic flipper. The purpose of this guide is to explain all of the reasoning behind the design decisions during the creation of Bucki. This guide will go in depth on why certain designs were chosen as well as explaining some of the calculations used to support those decisions.

Design Overview
As a flipper, Bucki launches its opponents into the air using rapid, impulsive force. To this end, it utilizes a liquid CO2 system to power an air cylinder and actuate its flipping motion. The liquid CO2 is stored in pre-filled 20 gram cartridges, which are inserted into a specialty regulator to reduce the operating pressure to an amount manageable by the most fragile elements of the design.
Upon exiting the regulator, the decompressed CO2 is held upstream of a 3 port/2 state solenoid valve, which allows for intake of air into the piston and exhaust following the end of its stroke. This solenoid is controlled using signals from a standard RC controller interpreted by a microcontroller.
Also upstream of the solenoid valve, the system features a bleed valve to empty the system following operation and a pressure gauge to monitor the regulator’s output. These components are connected with a variety of connectors and lengths of tubing.
Design Decisions
- A liquid CO2 system was chosen for its small form factor and reduced weight relative to the standard HPA design.
- HPA necessitates a larger tank that needs to be recharged, while CO2 cartridges can be switched out rapidly.
- Recharging a HPA tank would require a more powerful air compressor (such as a SCUBA or paintball one) than the ones that are easily available on campus.
- HPA operates at pressures and capacities that are excessive for the other limits imposed on the system.
- The specialty regulator was chosen for its ability to pierce CO2 cartridges and convert their input to a standard NPT size.
- The solenoid valve chosen was decided based on its low weight and size, but other options (such as some valves from Parker) would have been superior in terms of pressure and power.
- The system was primarily constrained by weight and size and would've been better served with a larger piston and greater pressure.
- NERC rules were relatively loose, but they required the use of a gauge and a method to bleed the system.

Notes:
Naming Inspiration: Nothing good; should've been Topsi Turvi
Took least amount of damage of any bot in Motorama history
