Visualising, Design, and Creation of Components
            Visualising, designing, and creating robotic components involves several steps and considerations. Here is an
            overview of the process:
               • Identify the Purpose: Determine the specific function and purpose of the robotic component. It understand
              their intended role and how they will interact with other parts of the robot or the environment.
               • Conceptualisation: Create a conceptual design of the component. This can be done through sketches, diagrams,
              or using Computer-Aided Design (CAD) software. It consider factors such as size, shape, range of motion, and
              any specific mechanical or electrical requirements.
               • CAD Modelling: Use CAD software to create a detailed 3D model of the robotic component. This allows you to
              refine the design, visualise its appearance, and simulate its behaviour. CAD software provides tools to create and
              manipulate parts, apply materials, and assemble components.
               • Mechanical Design: Consider the mechanical aspects of the component, such as structural integrity, load-
              bearing capabilities, and range of motion. Ensure that the design is robust enough to withstand expected forces
              and movements.
               • Electrical Design: If the robotic component includes electronic or electrical elements, plan the wiring, circuitry,
              and connections. Consider factors  such as power requirements, signal transmission,  and compatibility with
              other components or control systems.
               • Material Selection: Choose appropriate materials for  the  component  based on  its function,  mechanical
              properties, and environmental factors. Consider factors like weight, strength, durability, and cost. The common
              materials used in robotics include metals, plastics, composites, and specialised materials like carbon fiber.
               • Prototyping: Create a physical prototype of the component using rapid prototyping techniques such as 3D
              printing or CNC machining (Computerized Numerical Control). This allows you to evaluate the design, test its
              functionality, and identify any necessary modifications or improvements.
               • Testing and Iteration: Test the prototype to validate its performance and functionality. Identify any issues or
              areas for improvement and iterate on the design as necessary. This may involve making adjustments to the CAD
              model and creating subsequent prototypes for further testing.
               • Production: Once the design is finalised and validated, prepare the necessary manufacturing specifications.
              Depending on the complexity and quantity of the component, it can be manufactured in-house or outsourced
              to a specialised manufacturing facility. Techniques such as injection molding, CNC machining, or additive
              manufacturing may be used, depending on the requirements.
               • Integration: Integrate the robotic component into the overall robot system. Ensure proper alignment, fit, and
              functionality with other components or systems. This may involve mechanical assembly, wiring, and programming
              or configuring any control interfaces.
            Throughout the process, it is essential to consider factors such as safety, cost-effectiveness, and manufacturability.
            Collaboration with multidisciplinary teams, including mechanical engineers, electrical engineers, and robotics
            experts, can help ensure a comprehensive and successful design and creation of robotic components.

            Tinkercad is a free-of-charge, online 3D modelling program that runs in a web browser, i.e., it is a web-based
            Computer-Aided Design (CAD) software that allows users to create 3D models for various purposes, such as
            3D printing, electronics, and engineering projects. Since it became available in 2011, it has become a popular
            platform for creating models for 3D printing as well as an entry-level introduction to constructive solid
            geometry in schools.
