**Problem**:
Fire and gas Leakage can cause serious threats to the safety of people and property. In those emergency circumstances, it’s usually dangerous for firefighters to enter the scene directly, as the fire or toxic gas can be life-threatening. However, if the details of the situation remain unknown, it will be difficult for firefighters to plan to rescue or eliminate the danger.

**Solution Overview**:
We propose that a remotely-controlled robot equipped with cameras and sensors is needed to investigate and evaluate the dangerous environment. The robotic car can be controlled remotely. In our design, the cameras can be fitted to a robotic arm so that we can get images and videos from different views and perspectives. Our solution hopes to get real-time videos from cameras and data from multiple sensors. The images and sensor data can provide firefighters with detailed information about fire and gas leak scenes.

**Solution Components**:
- [Subsystem #1] Robotic car with motor control: We plan to use H-bridge and PWM to control the motion of the robotic car. Using ultrasonic sensors to detect obstacles and avoid crashing.
- [Subsystem #2] Wireless receiver and transmitter (Wi-Fi, cellular, or building our own RF): Receive the robot control instructions from the user, and transmit the camera images and sensor data back to the user.
- [Subsystem #3] Fire and gas leak detection: Using an infrared sensor, CO sensor, temperature sensor, etc., to detect the fire and gas leak.
- [Subsystem #4] Robotic arm: The cameras can be fitted to a robotic arm so that we can get images or videos from different views and perspectives and fully examine the environment.
- [Subsystem #5] User-end system and interface: Users should be able to control the robotic car wirelessly and get image and sensor data from the robotic car.

**Criterion for Success**:
- Users should be able to wirelessly control the moving speed and directions of the robotic car.
- Cameras and sensors installed on the robotic car should be able to send meaningful images and data back to users. Users should be able to receive those images and data.
- The robotic arm should be able to be controlled by users and help adjust camera angles and views.

**Additional Note**:
- Mechanical design is one difficult aspect of this project. We need to install cameras on the robotic arm and place the robotic arm on the robotic car.
- It seems impossible to demo the fire or gas leak situations in the ECEB lab. We plan to test the functionalities of this robotic car by ourselves (under safe conditions) and record videos for presentation.
- We decided to build our own RF.

Featured Project

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
