When curiosity is sparked...

This is the third year that I am teaching a course titled "Introduction to Robotics" as part of our regular curriculum at Sonoma Academy. Click here to access our class website. 

The goal of the first few weeks is to answer the question "What is Robotics?" Merriam-Webster defines a "Robot" as...  

...a machine that resembles a living creature in being capable of moving independently (as by walking or rolling on wheels) and performing complex actions (such as grasping and moving objects). 

I have always struggled to help students derive there own definition of what a "Robot" is using standard curricular materials.

The "...moving independently" portion of the definition is not a problem initially, as most systems (Lego Mindstorm, VEX EDR, etc.) feature the ability to autonomously program the robot to perform complex tasks. Not a problem. 

However, when relating a definition of the structure of robotic competitions such as those seen in FRC, and VEX I have always struggled.

Each of these competitions features a "telops" phase, where a driver is remote controlling the robot to perform a series of tasks in addition to an "auton" phase, where the robot performs the tasks individually. 

Logically explaining to students that remote controlling a system is a branch of robotics is difficult. 

If a human is in control, is the machine still performing a series of complex tasks? 
How do we rationalize the inclusion of a human controller into the field of Robotics? 

This year, I decided to tackle the conceptually challenging topic of rationalizing the role of the "telops" in robotics. Here is what I did for the first two weeks: 

1. Create remote controlled combat robots using the Finger Tech Viper Kit and a simple transmitter-receiver system. 
2. After our competition, ask students the following question: If we were to give our combat robots their own "brain" where would we plug it in? (After much discussion, all of the students noted that we would replaced the transmitter-receiver system with a microprocessor). 
3. Perform a series of lessons on the Arduino Uno system. 
4. Challenge students to replaced the receive with a programmed Arduino Uno and Ultrasonic sensor capable of controlling their robot to combat autonomously.
5. When done, pose the following discussion prompt: In the remote controlled robot, what program was controlling the robot? In the autonomous robot, what program was controlling the robot? 

Student responses were fascinating. All students understood that in the Arduino Uno controlled autonomous robot, the program written living on the microprocessor provided commands directly to the motor controllers, guiding the robots movements. 

The remote controlled robot "program" surfaced different, incredibly intriguing responses such as: 

God programmed us to send a signal to the receiver to control the robot. 
Evolution programed us to send a signal to the receiver to control the robot. 
Education programmed us to send a signal to the receiver to control the robot. 

Amazing questions also emerged: 

Is it possible to program the Arduino to fight more efficiently than the remote controlled robot? 
What happens when the intelligence of the Arduino Uno matches that provide by God, Evolution, etc.? 
Is this related to the Technological Singularity? AI? 

Although this unit laster longer than I would have liked, the physical motion of removing the transmitter-receiver system, and replacing it with a preprogrammed microprocessor opened up incredible discussion about what it means to be "...moving independently". 

I freaking love teaching. 

Campers spent day 1 using the Microbit to learn the basics of interfacing physical hardware with coding. Campers worked through a series of modules, leading to their own invention that they will showcase on our final day. Click here to see all modules via our leaderboard, and click here to see the handbook that contains links to all activities. A few images from today are shown below.  

During Day 1 of the STEM portion of "Soccer & STEM Camp", campers built ball pitching machine to experiment with the process of "gearing up". After building the same machine, campers were challenged to modify their projects to change the speed and/or structure of their machine. Today, Day 2, campers will apply their knowledge of gearing to build a Robotic Dragster. See a few images of Day 1 below.
