Retired Engineer Builds Necktie-Tying Robot: A Mechanical Marvel

The transcript describes a 65-year-old engineer, Goldstein, who spent six years creating a necktie tying robot with 350 movements. Inspired by a childhood visit to a chocolate wrapping machine, Goldstein pursued mechanical engineering. Despite the robot's complexity, it is impractical, taking nine minutes to tie a tie and costing $250,000. Ironically, Goldstein dislikes ties. The robot will be displayed at the Franklin Institute.

What inspired Goldstein to pursue mechanical engineering?

• A visit to a chocolate bar wrapping factory

• A school project on robotics

• A fascination with neckties

• A family tradition in engineering

What was one of the main challenges Goldstein faced while building the robot?

• Designing the robot's appearance

• Programming the robot's movements

• Finding the right materials

• The unpredictable way the tie would fall

How long does the necktie tying robot take to complete its task?

• 9 minutes

• 5 minutes

• 15 minutes

• 20 minutes

What is the approximate cost of the necktie tying robot?

• 250,000 U.S. dollars

• 500,000 U.S. dollars

• 100,000 U.S. dollars

• 50,000 U.S. dollars
