Inspiration
One of our best friends is a wheelchair user, so we chose to create CosmoBot to make wheelchair maneuvering as easy and accessible as possible.
What it does
Users can wear their Emotiv headsets, and concentrate, thinking of four different motor images: pushing an object, pulling an object, turning left, and turning right. These commands are then translated to our Arduino, which controls the wheels of our prototype wheelchair.
How we built it
Our Emotiv Insight headset detects commands such as push, pull, left, and right. These are then run through our Node-Red workflow to integrate them to linear instructions such as forward, backward, left, and right for our Arduino. After running our script, users can use the Emotiv headset to control CosmoBot with our minds.
Challenges we ran into
Setting up our hardware was definitely the most challenging part, as we had a limited supply of components available, and were complete beginners to the process.
Accomplishments that we're proud of
We're proud that we got our Arduino working! As people who had absolutely no experience starting off, we learned a lot, not just about the technical circuitry process, but also about working under pressure and persevering.
What's next for CosmoBot
We'd like to add more robust headset control, and refine the movements of our DC motors. Afterwards, we'd like to scale up our hardware to test with real wheelchairs, and possibly look towards controlling 4 wheeled vehicles and aircrafts in the future.
