A group of students from Iowa State University developed a device that enables a child with Cerebral Palsy to participate in basketball games with friends. The basketball shooter attaches to a wheelchair and is push-button activated.

Igubal® bearings from igus® are used in the shot mechanism. Specifically, igubal pillow blocks are used to hold the shaft that wraps aircraft wire and enables the shot mechanism to be pulled back. Even with a radial load of 250 lbs., the igubal bearings are low-friction, keeping a minimal amount of energy from being wasted when a transfer of energy from the motor to the pullback spring takes place. When the motor and clutch are disengaged, the low-friction also enables the shaft to freely spin at large angular velocities.

In addition to igubal, a DryLin® linear guide system was used. DryLin is used to engage and disengage the mechanical clutch of the basketball shooter.
