The Arcade Style Button Pusher Game
Designed and built an automated linkage system to press arcade buttons in rapid sequence
The Record Breaking Performance
The Criteria:
Performance (# of correct buttons pressed in a one minute span)
Volume minimization
Craftsmanship
The Challenges:
Achieve predictable, FAST motion while preventing absolute failure
Hyper-optimize for maximal performance
Project Acheivements
Fig. Assembly CAD Model, Fusion360
Fig. linkage electronics
Unique Design
Only group to implement non-traditional four-bar linkage
Actuated by just a servo motor and DC motor, transmission through a timing-belt system
→ MOI reduced 2.5x
→ High speed actuation
→ Adjustable transmission
Final Design
Fig. compact ground plate
Craftsmanship
Manufacturing using the CNC lathes and mills for metal components
3D printing prototypes and POCs
→ Precision machining + manufacturing techniques
→ Maintains optimal performance
→ SLS Printing! (main linkage)
The Result
Fig. final assembled linkage with electronics
Learned the challenges of mechanical optimization
balancing speed, inertia, transmission ratio, and system volume
Strengthened ability to design mechanisms that are both precise and repeatable
translating kinematic concepts into a manufacturable model
creating a reliable system through iteration and prototyping
