3.1 Need Statement: MECHANIZED SMART LAMP

Conventional lamps require user interface command with automatic adjustment to change the direction or position of light, has mechanical movement, electronic control, and smart user interaction to provide adjustable lighting. lamp should allow the user to conveniently control the lamp's movement and light direction, making it suitable for study tables, workspaces this is the next generation of IOT coming in the future.

Traditional desk lamps require manual adjustment of position, brightness, and operation. This can cause inconvenience and may not provide proper illumination when the user's position changes.

Therefore, there is a need to develop a Mechanized Smart Lamp that can detect the user, automatically direct the light, adjust brightness, and provide simple manual control.

The proposed system uses sensors, servo motors, and a microcontroller to provide convenient, directional, energy-efficient, and portable lighting.

Stable movement requires proper balancing.

Identified Requirements: User detection.

Automatic directional movement.

Pan and tilt mechanism.

Variable brightness control.

Warm and cool lighting.

Manual button/touch control.

Battery and AC operation.

Lightweight compact structure.

Stable mechanical base.

Low-power components.

Safe enclosed mechanism.
