Answers: Can a robotic soccer goalie block a penalty kick from Cristiano Ronaldo?

• robotic soccer goalie
• motion tracking cameras
• soccer penalty kicks
• Cristiano Ronaldo
• motorized goal system
• retroreflective markers
• engineering design and testing

What it concludes

• A robotic goalie using 22 high-speed infrared cameras and 50-horsepower motors can successfully block a penalty kick from Cristiano Ronaldo.
• Forklift vibrations and extraneous ground movement can severely disrupt the accuracy of precision motion-tracking cameras.
• Sandwiching a piece of dense foam between two sheets of carbon fiber creates an ultra-lightweight and strong material suitable for high-speed robotic components.
