Great start on the prosthetic leg design!

• What activities will this prosthetic leg support? think about different scenarios, like walking, running, or balancing, and how the prosthetic might adapt to each. think about the range of motion and flexibility needed for different tasks.
• Who is the target user? Is this designed for children, adults, or athletes? Different users will have unique needs in terms of weight, durability, and flexibility. For example, some prosthetics are designed for only walking, while others allow running or climbing stairs.
• What materials are you using for the prototype and in real life what would it be made of.Have they considered shock absorption or cushioning?think about lightweight but strong materials, such as aluminum or carbon fiber, for durability without adding too much weight. Consider the foot’s surface or grip, as different textures (like rubber or textured cardboard) could help with traction and prevent slipping.For prototype use cardboard with foam.

What unique features can they add to make it stand out?

• Adding storage for small items.

Incorporating light sensors or small LEDs for visibility at night.

• Adding a shock-absorption feature if the user will be on different types of terrain.

Prototyping

•  You could simulate a knee joint by connecting two cardboard pieces with a paperclip hinge or using rubber bands for flexibility.Try out their prototype and observe where it feels stable or unstable, what parts work smoothly, and what could be improved. This approach can help you refine their design.
• Keep iterating and testing to see how it performs!

Cool idea!

Concept/shape

• What specific activities or tasks do you envision users accomplishing with this cyborg thumb?
• Have you considered how easy it would be for users to put on and remove the cyborg thumb? Could the shape or attachment method be adjusted to make it more user-friendly?

Functionality 

• Could there be a locking mechanism to hold the thumb in place once it grips something, allowing the user to rest their leg without losing the grip?
• How comfortable is it to use over long periods? Would adding padding to the attachment point on the leg improve comfort?
• Have you thought about making the thumb detachable for easy storage or transport? 
• What materials are you considering for the thumb and strings if this was to be built in the future ? 
• Could there be a safety release mechanism if the spring or string pulls too hard to prevent potential injury?
• Over time, could this design be adapted to include electric motors or sensors? This would allow the thumb to operate autonomously without needing manual pulls, potentially controlled by subtle movements or pressure sensors.

Ideas for Prototyping

• For an initial prototype, try using lightweight, flexible materials like cardboard and soft foam to create a comfortable, functional version.
• Lights could provide feedback when the thumb is in use. For example, LED lights could turn on when the thumb grips something, signaling activation.
• A servo motor could enable more precise control over the thumb’s movement, making it more versatile. Here’s how to approach it:

1. Type of Servo:

   • Micro Servo: A small, lightweight servo is ideal for this project, as it would provide adequate torque without adding too much bulk or weight.

   • Continuous Rotation Servo: If you want the thumb to rotate freely in one direction, a continuous rotation servo is an option, but it may not be as effective for precise gripping.

2. Power and Control:

   • Battery Pack: A small battery pack can power the servo. A 5V power supply would work well with most micro servos.

   • Arduino or Microcontroller: To control the servo, you’ll need a microcontroller like an Arduino or a smaller alternative like an Adafruit Trinket. This will allow you to program movements and trigger actions.

These resources will be important for prototyping and inspiration

• How does the shape of the jetpack accommodate the user’s body? Are there any parts that need padding or a curved design to improve comfort?
• How does the shape affect aerodynamics? Would a more streamlined design reduce drag?

• Emergency Features: How does the jetpack handle sudden power loss or emergency landings? Features such as automatic hovering or a backup battery could enhance safety.
• Propeller Safety Mechanisms: Since the design operates with open propellers, exploring additional shielding or sensors to detect nearby obstacles could improve safety for both the user and others.

Prototyping Suggestions:

• Propeller and Thrust Simulation: Use lightweight cardboard or plastic discs for propellers and attach them to thin wooden dowels or skewers to represent the rotating mechanism. You can manually turn them to show the concept of directional thrust. Mount these on a foam or cardboard frame to illustrate the overall shape and function.
• Joystick and Throttle: Craft a joystick and throttle lever using small blocks of wood, foam, or clay. You could mount them with rubber bands or hinges to allow slight movement, simulating user interaction.
• Battery and Central Case Use a small box or piece of foam for the central case. Mark it with areas where the battery, charging port, and small computer would be located. This can help demonstrate the internal layout.
• Adjustable Parts and Movements: Pipe cleaners, twist ties, or floral wire are great for representing adjustable components. You can bend them to show possible movement, like adjusting thrust direction.
• Material Simulation: Use different textures or colors of cardboard or foam to represent the various materials in the design (e.g., lightweight metal, aluminum casing for propellers).

• Consider adding red LEDs to simulate emergency indicators. These could be placed on the central case to represent alerts for low battery or other system issues.
• Propeller Simulation: Consider using small electric fans to prototype the effect of directional thrust and its control through the joystick.(powered by dc motors)
• Control Responsiveness: Testing joystick and throttle controls with simple servos can simulate the feel and response users might experience.
• Adjustable Power Pack: Mock-up a detachable battery module to test its ergonomics and weight distribution on the design.

Innovative Details: The adjustable wires and sensors integrated into the glasses indicate a thoughtful approach to both comfort and functionality. The inclusion of a sensor on one side suggests the glasses may have some form of interactive or augmented capability, which is an excellent foundation.: The idea of a chip that goes into the head is intriguing. This approach demonstrates an awareness of how technology can seamlessly integrate with the body, although it raises questions around feasibility and user safety.The adjustable wire is a smart choice, allowing users to fit the glasses according to their needs. This flexibility could make the glasses suitable for a broad range of users.The sensor on the glasses could potentially offer various functionalities, such as real-time data display or environmental scanning, but more details would help clarify its specific role and benefit to users.This design could serve multiple user groups, such as tech enthusiasts or individuals who benefit from augmented reality in professional settings. However, refining the design for a specific group, would make the product more impactful.

Leading questions for direction (to help enhance the design/concept)

Concept/shape

• Target Audience: Decide on a primary user group—such as individuals with visual impairments, outdoor enthusiasts, or general tech users. This can guide the design features. For example, if intended for visually impaired users, the glasses could include tactile or audio feedback
• Primary Functionality: Clarify what specific functionalities the glasses will offer. Are they meant for augmented vision (e.g., improving sight, displaying information), or are they targeting another sense or purpose? This clarity will help refine design choices.
• Sensor Role: Define the sensor’s role. For example, will it detect environmental cues (like proximity or light levels), provide user feedback, or display notifications? A well-defined sensor function can lead to a more effective design.

Functionality 

• What specific capabilities does the sensor provide to the user? (e.g., real-time data display, environmental analysis)
•  Think about adding environmental sensors, such as for detecting brightness or obstacles, if the glasses are intended for visually impaired users.
• If the design includes electronic components, consider where a small battery or charging port could be placed. This feature should be easy to access but discreetly integrated into the frame.

Prototyping Suggestions:

• Adjustable Components: Use thin, flexible materials like pipe cleaners, twist ties, or floral wire to simulate the adjustable wire elements in the glasses. These materials are easy to manipulate and can help you test how the design adapts to different head shapes.
• Frame Structure: For a lightweight, flexible frame, consider using cardboard or craft foam sheets. These can be easily cut and shaped to mimic the glasses frame and allow for adjustments.
• Sensor Simulation: To represent the sensor, you could use small, lightweight objects like bottle caps or pieces of craft foam attached to the frame. This can help visualize the placement and size of the sensor.
• Chip Integration: For the chip idea, you could tape a small piece of cardboard or use clay to represent how the chip would interact with the user’s head. This will let you test both comfort and positioning.

The Nano Arm concept sounds innovative and could definitely appeal to a broad audience. The idea of designing a device for "lazy people" could be broadened to include those with mobility issues, elderly users, or anyone who struggles to reach for items. This could enhance the marketability of the Nano Arm.Lightweight materials will be essential for ease of use, and a compact design will make it more practical for everyday tasks. A sleek, modern aesthetic could also appeal to a broader audience. I recommend they draw diagrams at the end or before the prototype that outlines how to use the Nano Arm, like a small storyboard or 3 frame showing how it extends, how it grips, and how it releases. 

Leading questions for direction (to help enhance the design/concept)

Concept/shape

• Who is the primary target audience for the Nano Arm (e.g., elderly, busy professionals, people with disabilities)?
• What specific tasks do you envision users needing assistance with, and how can the Nano Arm address these needs?

Functionality 

• What length and weight should the arm be to balance usability and portability?
• How will users control the arm? Would a pull-string mechanism be sufficient, or should you explore other control methods?
• What safety mechanisms will be integrated to prevent injury or damage to items being grabbed? Highlight a reliable gripping mechanism that ensures items won’t slip or drop when extended.
• How will you ensure the arm is stable and secure when extended to reach for items?
• What materials will you use to ensure the arm is lightweight yet durable?
• What features or benefits will be emphasized to attract potential users? Think of Interchangeable Attachments, where you offer various attachments (e.g., claw for grabbing, brush for cleaning, or a small scoop) that can be easily swapped out based on user needs.
• Maybe add Voice Activation: consider incorporating voice commands to extend or retract the arm, enhancing convenience.
• Consider features like LED lights for visibility in low-light conditions
