Session 4 8th

In 3D modeling, why is it important to think about how parts connect before building the model?

• It saves internet data

• It helps reduce the number of shapes used

• It ensures the parts will fit and function correctly when printed

• It adds animation to the model

Which part of a humanoid robot helps it simulate bending or movement like a human?

• Brackets

• Joints

• Casings

• Screws

In TinkerCAD, what is the advantage of using basic shapes for designing robot components?

• They are animated automatically

• They are easy to combine into more complex structures

• They move on their own

• They change color when printed

How does 3D designing help before building a real robot?

• It adds sound effects to the robot

• It avoids the need for coding

• It helps visualize and test the structure virtually

• It creates a robot in augmented reality

What makes a robot design “humanoid”?

• It includes wheels and arms

• It has sensors and lights

• It resembles human features like arms, legs, and head

• It is taller than other robots

Why is alignment important when assembling parts in a 3D model?

• It makes the robot look more colorful

• It helps save shapes

• It ensures parts fit correctly and the robot stands upright

• It lets the robot float in the air

What happens if parts of a 3D model overlap without proper alignment?

• The model looks better

• The design becomes unprintable or unstable

• It uses fewer shapes

• It saves memory

What is the most important feature of a good 3D humanoid design in TinkerCAD?

• Bright colors

• Use of circles only

• Logical structure and balance

• As many shapes as possible

What type of shapes are most useful for designing robot legs and arms in TinkerCAD?

• Stars and hearts

• Spheres and pyramids

• Cylinders and boxes

• Donuts and text

How does TinkerCAD help in learning real-world robotics?

• By adding music to robots

• By offering coding simulations

• By allowing users to build, modify, and visualize robot parts virtually

• By showing cartoons of robots
