Summary

TLDRThe video script details the creation of a trick bowling ball that can be steered by the bowler's body movements. The inventor, inspired by the asymmetry of a standard bowling ball, collaborates with a toy designer to engineer a mechanism resembling BB-8. The ball is equipped with an inertial measurement unit that communicates with a servo motor, altering its center of gravity to turn. After initial trials, the team perfects the ball's performance, achieving strikes by hitting pins at a specific angle. The video concludes with a fun bowling session where the inventor's 'Jedi powers' impress friends and family.

Takeaways

  • 🎳 The bowling ball described in the script is designed to turn in the direction the bowler leans, suggesting a high-tech modification.
  • 🛠️ The ball is constructed from a real bowling ball, which is found to be asymmetrical with the center of mass not at the center point.
  • 🔩 A friend with a machine shop, Mark, hollows out the ball to make room for the internal mechanism.
  • ✈️ The creator travels to London to collaborate with James Bruton, a mechanical and electrical engineer with a background in toy design.
  • 🤖 The mechanism inside the ball is inspired by BB-8 from Star Wars, aiming for a similar functionality.
  • 📡 The bowler controls the ball's direction by leaning, which is detected by an inertial measurement unit (IMU) on their back.
  • 📶 The IMU sends signals to the ball via radio waves, which are received and processed to adjust the ball's direction.
  • 🤖 An Arduino and a servo motor inside the ball work together to rotate a heavy pendulum, changing the center of gravity and turning the ball.
  • 🎯 To achieve a strike, the ball must hit the pins at an angle between three and six degrees off center.
  • 😅 Initially, the creator struggles to get strikes due to incorrect technique but eventually masters it.
  • 🎉 The final test with family friends at a local bowling alley demonstrates the ball's effectiveness and the fun it brings.

Q & A

  • What is the main feature of the bowling ball described in the script?

    -The bowling ball has a mechanism that allows it to be steered by the bowler's body movements, specifically by leaning in the desired direction.

  • How long has the idea for this bowling ball been on the creator's bucket list?

    -The idea for the bowling ball has been on the creator's bucket list for over three years.

  • What was the first step in creating the trick bowling ball?

    -The first step was to understand the internal structure of a regular bowling ball, which revealed that they are not symmetrical.

  • Who helped hollow out the bowling ball?

    -The creator's friend Mark, who owns a machine shop, hollowed out the bowling ball using a lathe.

  • Why did the creator need to go to London?

    -The creator went to London to meet James Bruton, a mechanical and electrical engineer genius who used to be a toy designer, to help with the engineering design of the ball.

  • What is the role of the inertial measurement unit in the bowling ball system?

    -The inertial measurement unit is attached to the bowler's back and senses the bowler's orientation, sending commands to the ball to turn in the direction the bowler leans.

  • How does the ball receive commands from the bowler?

    -The ball has a receiver that gets the signal from the inertial measurement unit via radio waves.

  • What component in the ball controls the movement of the heavy pendulum?

    -An Arduino, which serves as the brains of the operation, tells the servo motor how much to rotate.

  • How does the heavy pendulum affect the ball's trajectory?

    -The servo motor rotates the heavy pendulum, which alters the center of gravity of the ball, causing it to turn in the direction the bowler leans.

  • What is the optimal angle for the ball to approach the pins for a strike?

    -The optimal angle for the ball to approach the pins for a strike is between three and six degrees from the point directly in front of the pins.

  • What is the purpose of the limit switch on the bowling ball system?

    -The limit switch is used to toggle the ball's steering ability on and off, allowing the bowler to bowl normally without assistance when needed.
