HazardArm

Inspiration

Our inspiration for the HazardArm comes from working in laboratories. Many engineers, scientists, and technicians have to work with chemicals or other substances that are can be harmful if exposed. Chemical hoods do not safeguard against spills or other accidents.

What it does

The HazardArm is a robotic arm that can hold objects, such as beakers and test tubes. It is able to reflect the movement of the user’s arm. This enables the user to conduct experiments without risking potential exposure.

How we built it

We used materials mainly from the BE Lab. The main housing as well as the arm is laser cut MDF. The Arduino and the circuitry are housed in the main housing.

Challenges we ran into

Originally, the servos move all over the place. The cause of this is that the data from the accelerometer fluctuates quite a bit.

Accomplishments that we're proud of

Getting the IOT button to work consistently and robot arm to reflect arm movement.

What we learned

We learned to do live data processing. This is used to smooth the movement of the servos.

What's next for HazardArm

We could add a claw that has a load cell built into the claw. This would be convenient to the user as it can read the weight of the object being held. Also a smaller accelerometer could be added to the fingers to control the claw.
