Cameron Clapp competes at the 2005 Endeavor Games with the help of C-Leg prosthetic devices. Microprocessors in the knee guide a hydraulic system that influences each step.

Processors have been used to add stability to prosthetic limbs since the mid-1990s. Otto Bock HealthCare has been successfully producing the chip-controlled C-Leg limb since 1999.
