Bowling Better
for Everyone.
Bowl4All is an assistive technology project created by CU Boulder engineering students to make bowling more accessible, more independent, and easier to share with others.
Inclusive Bowling for Everybody.
We are a team of engineering students at CU Boulder building an assistive technology device to increase participation in the Special Olympics and beyond. Our primary goal is to make this project easy for others to recreate using accessible materials and clear, simple instructions.
Affordable
The product can be made for less than $120 and utilizes a switch families already have.
Portable
Compact enough to fit inside a standard-size bowling bag and lighter than 10 pounds.
Reproducible
Built to be recreated with easy-to-find materials and straightforward instructions.
