Inspiration
Natural disasters and evacuation. We believe that in dangerous situations, it's better to send a robotic scout to check the conditions before sending people. We wanted MALL-E to report potential for fires or explosions- but reading temperature, humidity, and gas measurements of hard to reach areas. We hoped to make it remote operated through gesture control for a simpler control mechanism. To aid control, we would report back the ultrasonic distances of what it saw in front of it, and map where it has been moving.
How we built it
We used an Arduino as the main microcontroller. Depending on the angle of an accelerometer, the motors will move the robot forward, left/right and back. A gas, temperature, and ultrasonic sensor would be putting outputs to an LCD screen. The LCD screen would also display the map, based on the accelerometer control values.
Challenges we ran into
Sensor Integration: When to utilize one pin or another, as some sensors would rely on the same functionality.
Accomplishments that we're proud of
Mapping the accelerometer outputs Motor Control
What we learned
Integration is the difficult part- especially when limited with pins and timers of one microcontroller.
