Explain your impact assessment on those four pillars: social, economic, environmental, and natural resources. And, explain how this assessment will influence your project concept and goals.
Does your prototype directly address a specific need or improve the quality of life for its target audience?
Yes, the wooden hand-grasping stimulation device is designed to provide entertainment and therapeutic benefits, such as improving hand-eye coordination, fine motor skills, and stress relief. It can enhance the quality of life for users, particularly those seeking a tactile and engaging activity.
Have you considered inclusivity or accessibility to ensure your solution benefits a diverse group of people?
The design can be adapted to accommodate users of different ages, abilities, and hand sizes. For example, adjustable grips or varying difficulty levels can make it accessible to children and adults
Is your prototype designed to be affordable and cost-effective for its intended users?
Yes, the use of wood as the primary material makes it cost-effective to produce. The simplicity of the design also keeps manufacturing costs low, ensuring affordability for a wide range of users.
Does your project contribute to local economic growth, such as supporting local manufacturing or jobs?
If produced locally, the project can support local artisans, carpenters, or small-scale manufacturers, contributing to the community's job creation and economic growth. also Affordable Rehabilitation Tools: By providing a cost-effective solution for hand rehabilitation, my project can support local healthcare providers, such as physiotherapy clinics and hospitals, in offering better services to patients at a lower cost.
Training and Maintenance Jobs: Local technicians can be trained to assemble, maintain, and repair the device, creating additional employment opportunities.
Have you taken/going to take steps to use materials efficiently, reduce waste during production, or repurpose leftover materials from your prototype?
Wood is a renewable resource, and the design can incorporate efficient material usage to minimize waste. Leftover wood scraps can be repurposed for smaller components or other projects, reducing environmental impact.
Does your solution promote environmental awareness or encourage sustainable practices in its intended use?
By using sustainably sourced wood and emphasizing eco-friendly production methods, the project can raise awareness about sustainable practices and encourage users to value environmentally responsible products.
Are you going to responsibly use sourced or recyclable materials in your prototype?
Yes, the project will use responsibly sourced wood and can incorporate recyclable or biodegradable materials for additional components.
Does your solution help conserve essential natural resources like water or energy?
The production process can be designed to minimize water and energy usage. Additionally, the durability of the wooden design ensures a long product lifespan, reducing the need for frequent replacements and conserving resources over time.also Home-Based Rehabilitation: The device allows patients to perform rehabilitation exercises at home, reducing the need for frequent visits to healthcare facilities, which in turn reduces transportation-related energy consumption and carbon emissions.
My project is a function training for hand grasping in the entering way.
many patients with hand impairment like fractures have problems gripping the hand by the way, hand grasping is the most important function of the hand for a patient's daily activity.
so I decided to make a machine that will asses and train hand grasping by when we power the machine orders like ( grab the component for 20 scend/grasp 5 times/hold and relax 6 times) will appear on the LCD screen also the force sensor (in the hand grasp component ) will calculate the power of hand grabs by numbers and show it in the LCD screen and that's will be helpful for educate and encourage the patient to do the task also will give me biofeedback about the progress of the patient hand.

Describe how your project will leverage maker tools like laser cutters or 3D printers to reduce waste, and increase maintainability. Also, explain your choice of materials such as fabric, plastic filament, or recycled plastic sheets to support green innovation. Select materials with low environmental impact, and explain their relevance to your project.
Laser Cutters:
Precision Cutting: Laser cutters will be used to precisely cut wooden components for the hand structure, minimizing material waste by optimizing the layout of parts on the wooden sheets.
Reusable Templates: Digital design files for the wooden parts can be reused for future iterations or repairs, ensuring long-term maintainability.
Minimal Waste: Any offcuts or scrap wood from the laser cutting process will be collected and repurposed for smaller components or decorative elements.
3D Printers:
On-Demand Production: 3D printers will be used to create small, intricate parts (e.g., joints or connectors) only when needed, reducing overproduction and material waste.
Repairability: Broken or worn-out 3D-printed parts can be easily reprinted, extending the lifespan of the project and reducing the need for complete replacements.
Material Efficiency: 3D printing allows for lightweight, hollow structures that use less material without compromising strength.
Waste Reduction: By combining laser cutting and 3D printing, we ensure efficient material usage and minimize offcuts. Scraps will be reused or recycled wherever possible.
Maintainability: Modular design principles will be applied, allowing individual components to be replaced or upgraded without discarding the entire hand. This extends the product's lifespan and reduces waste.
Low-Impact Materials: The use of sustainable wood, recycled plastics, and organic fabrics ensures that the project has a minimal environmental footprint while still being functional and visually appealing.

Describe how you’ll use Arduino programming, along with sensors and actuators, to create functions that improve your project’s efficiency, reduce resource use, or monitor environmental impact.
By integrating Arduino programming, sensors, and actuators, the wooden hand becomes a smart, energy-efficient, and sustainable device. This approach not only enhances functionality but also aligns with the project's goals of reducing resource use and promoting environmental responsibility.
Energy Efficiency: The Arduino will be programmed to optimize power consumption.
Force-Sensitive Resistors (FSRs): Embedded in the fingertips and palm, FSRs will detect the pressure applied during grasping. This allows the hand to adjust its grip strength dynamically, preventing damage to objects and reducing wear on the actuators
Servo Motors: Energy-efficient servo motors will control the hand's fingers and wrist. The Arduino will regulate their speed and torque to minimize power consumption while ensuring smooth and precise movements.
Resource Efficiency: By using sensors and Arduino programming, the hand will only use the necessary amount of force and energy for each task, reducing wear on materials and extending the lifespan of components.
Waste Reduction: The Arduino can monitor the condition of components (e.g., servo motor performance, sensor accuracy) and alert users when maintenance is needed, preventing premature failure and reducing waste.
Environmental Monitoring: If environmental sensors are included, the Arduino can log data on operating conditions (e.g., temperature, humidity) and suggest adjustments to improve durability and performance.
