Duo
Inspiration
A remote control pair of hands can be powerful in many fields. For example, it can be used for remote surgeries in rural areas, in space to repair parts without a manned mission, or in dangerous tasks such as underwater welding.
What it does
Duo mimics both left and right arms in real time using Leap Motion, node.js, and an Arduino Mega. In addition, a first-person perspective of the arms can be seen through a webcam connected to a VR headset. The webcam is capable of moving in two axes to point in the direction of the VR headset.
How we built it
Two modified open-source robotic arms were 3D printed. Servo motors were connected to an Arduino Mega. An inverse kinematics algorithm was coded in Node.js. Leap motion was integrated in Node.js. A webcam was fastened to two servo motors to allow first-person perspective. Much troubleshooting was needed.
Challenges we ran into
Motors not working
Inverse Kinematics
Time management
Accomplishments that we're proud of
Figuring out inverse kinematics Figuring out how to integrate VR with minimal equipment
What we learned
Hardware projects take twice the expected amount of effort to complete
What's next for Duo: Remote Control Pair of Hands
Better servo motors, smoother inverse kinematics algorithm, better VR experience
