How were inverse kinematics used in calibrating the hoop?
Press to flip
Inverse kinematics were used to calculate cable lengths based on the target backboard position for precise movement.
Describe a challenge encountered with ball tracking in the 3D hoop system and how it was addressed.
Ball tracking initially had issues with inaccuracies, which were addressed by using reflective markers and software improvements.
How does the cable and motor system function in adjusting the hoop?
The system adjusts the cable lengths to move the backboard to the desired position in real-time.
What is the key function of the microcontroller in the basketball hoop system?
The microcontroller controls the motor directions necessary for the hoop's movement.
What role does the big boss program play in the basketball hoop system?
It runs on a separate computer to predict the ball's trajectory and direct the hoop's movements.
What technology was used for precise ball tracking in the hoop system and why?
The OptiTrack camera system was used for precise ball tracking because of its high accuracy.
Explain the significance of using six degrees of freedom (six DOFs) in the hoop design.
Six DOFs allows for full movement and rotation in 3D space, enabling precise positioning of the hoop.
How did the use of overpowered motors affect the design process?
Overpowered motors were used because of their availability, impacting the design by increasing complexity.
Why was a power distribution box necessary in the prototype?
Due to the high power needs of the motors, a power distribution box was needed to manage and supply the power properly.
What was one of the initial design ideas before settling on a moving hoop?
The initial concept involved a specially shaped hoop that corrected for missed shots.
Why was a cable actuated robot chosen for the 3D hoop's movement?
It was chosen for its lightness and stiffness, crucial for efficiently adjusting the backboard.
What was the motivation behind making the 3D moving basketball hoop?
The motivation was to impress the speaker's wife by creating a hoop that corrects for missed shots.
What improvements are suggested for the future of the 3D hoop project?
Potential improvements include increasing speed and creating more dynamic interactions.
What was the primary goal of designing the 3D moving basketball hoop?
To create a basketball hoop that ensures every shot goes in by moving in 3D.
What was the purpose of using a disc brake system in the design?
A disc brake system was integrated for safety, to halt movement when necessary.
