4. How does Tinkercad support educational purposes?
Ans. Tinkercad is widely used in schools and educational institutions to teach design, engineering, and 3D modeling, offering
resources, tutorials, and projects for students.
5. What is the primary focus of Tinkercad's interface design?
Ans. Tinkercad's interface is designed to be user-friendly, particularly for beginners or those without prior CAD experience.
6. How does a prismatic joint differ from a revolute joint in terms of motion?
Ans. A prismatic joint allows linear sliding motion along a single axis, while a revolute joint permits rotational motion.
7. What is the purpose of creating a physical prototype during the robotic component design process?
Ans. The purpose of creating a physical prototype allows for the valuation of design, functionality testing, and identification
of necessary modification or improvements.
B. Long answer type questions:
1. How does a prismatic joint contribute to translational motion in mechanical systems?
Ans. A prismatic joint allows translational motion along a single axis, much like the motion of a sliding drawer. It restricts
relative motion between two connected parts to linear sliding or translation along a specific direction. For example,
Think of a simple sliding drawer found in a desk or cabinet. The drawer slides in and out along a fixed direction. This
sliding mechanism is achieved by using a prismatic joint, where one part of the drawer is connected to the fixed
structure via the prismatic joint, allowing linear motion in a specific direction.
2. How does visualising motion benefit the understanding and refinement of autonomous systems' movement?
Ans. Visualising motion adds a dynamic dimension to creations. It is essential for understanding and refining the movement
of autonomous systems. From mobile robots to robotic arms, capturing and analysing motion data, it aids in optimising
performance, safety, and efficiency.
3. How does a revolute joint function in terms of motion?
Ans. A revolute joint allows rotational motion about a single axis, like a hinge or a door. It restricts the relative motion
between two connected parts to rotation only, and the axis of rotation remains fixed. This type of joint is often used
when you need to create rotational movement in a robotic arm or a mechanical system. For example, Consider a
robotic arm used in manufacturing processes. Each segment of the robotic arm is connected to the next segment using
revolute joints. This allows the arm to move in a series of rotational motions at each joint, similar to how a human arm
moves at the elbow, shoulder, and wrist.
4. What are the key steps involved in the process of visualising, designing, and creating robotic components?
Ans. The process includes identifying purpose, conceptualisation, CAD modeling, mechanical and electrical design, material
selection, prototyping, testing and iteration, production, and integration into the robot system.
C. Competency-based/Application-based questions: #Problem Solving & Logical Reasoning
1. In the context of using robots for creating art, how could a robot be programmed to produce a painting? What factors
are essential to ensure the resulting art is both creative and expressive?
a. Programming the robot with a set pattern and using random colors for creative outcomes.
b. Equipping the robot with a pre-designed template and using fixed color palettes for consistent expressions.
c. Programming the robot with algorithms that enable exploration of various brushstrokes and colors.
d. Instructing the robot to replicate famous paintings to ensure historical relevance.
Ans. c. Programming the robot with algorithms that enable exploration of various brushstrokes and colors.
2. Develop a concept for a robot that can monitor pollution levels in a water body. Describe how the robot could collect
data, analyse it, and transmit the information to authorities for further action.
Ans. The underwater robot is equipped with sensors for measuring water temperature, pH levels, dissolved oxygen, and
pollutant concentration. It communicates using satellite signals or buoys, sending real-time data to research centers.
This helps scientists assess marine health and respond to environmental threats promptly.
