Comparing Navigation Methods With Boe-Botics

Alexander Davies, Jessy Gardner, Ethan Hurley, Brad Marion, Conor Mauro, Gianna Muto, Alexis Steelman, and Greta Waitz

Pros:

• Seeing the other participants’ pets
• Virtual tours and activities at night
• Step-by-step guidance through labs
• Virtual backgrounds
• We could make our own courses
• We were able to keep the robots
• Lots of inside jokes in the chat

Cons:

• Communication limited
• Not socializing face to face
• Hard to see screen

The Impacts of Remote Learning The Impacts of Remote Learning

Attending the ARC/ORNL program from the computer instead of in person proved to be difficult. However, there were some positive aspects.

Using the Whiskers for Navigation for Boe-Bot

• Whiskers are feelers that are

connected to the circuit on the Boe-Bot

• When the Boe-Bot would run into

something the Boe-Bot would backup a little and turn either right, or left depending on what whisker was hit

• If the left whisker was hit it would

backup and turn right, and if the right whisker was hit then it would backup and turn left.

Labs Labs

Traffic Light Lab

• Imitation traffic light
• Used red, yellow, and green LEDs
• Consisted of two separate “traffic

lights”, following the same course as an actual traffic light.

Reaction Game

• Let users test their time to react

after an LED light flashes.

• After the button was pressed,

computer displayed time to react.

• Computer programming

included anti

• cheat software.

Phototransistors Usage

• Phototransistors were wired to the front of the Boe

Bot.

• These phototransistors were then used to guide the

Boe Bot towards or away from a light source. Click here to view a demonstration of the traffic light lab.
