Getting a robotic arm to solve a puzzle might not seem like much, but two students in my CS328 Introduction to Robotics course have been learning how challenging stuff like this actually is. That's why I'm proud of what they have accomplished.
The classic "Towers of Hanoi" puzzle was invented by the French mathematician Édouard Lucas in 1883 and involves moving blocks or discs from one place to another according to certain rules. This is often difficult for a human to figure out -- just imagine programming a robot to solve it!
Here's a quick video of the robot in action:
The Towers of Hanoi is a common problem assigned to computer science students to help them organize their thinking about problem solving and iterative logic and most especially recursion.
The above video shows step one, which is to solve the problem by discrete programming moves. The next step, if they are up to it, is to take what they have learned and write the algorithms to solve this problem automatically. In any case, they are off to a fine start.
Yes, most of the equipment is older than they are, but it's all they need to learn the fundamentals. And it builds character!

That's Amy in the pink dress in front of the symphony orchestra last night. She's narrating George MacDonald's classic story of The Light Princess
, which she adapted into a narrative performance accompanied by a complete orchestral score, all written by her.
She also designed and commissioned the paintings on the screens so they could be displayed while she presents this work. It was very well received, and 700-800 people attended the world premier of The Light Princess.
Not to brag, but Kathy and I obviously have the most talented and hard-working daughters in the world.
For more highlights from the concert, you can check out Amy's blog here
And a couple more pictures for good measure:

One of the personal projects that has taken quite a bit of my time lately has been helping our symphony orchestra prepare for their mid-winter family concert.
This year, the all of the music including the featured work, The Light Princess" was written by my daughter, Amy, who is a music composition major at The Master's College.
Amy has been working for years on the arrangements for this concert which is called "Tunes, Tales, and Truths." The concert will feature the World Premier of “The Light Princess,” an adaptation of George MacDonald's beloved fairy-tale into orchestral music and narration.
The concert will also include a sweeping suite of original music: pirate legends, great awakenings, swinging jazz, and powerful tales of redemption and new life.
See that painting above? That's an original painting -- one of 10 -- that Amy commissioned for the concert. Working with the artist, Jay Wegter, Amy designed the theme and sketch for each piece of art which Jay then masterfully painted. These will be presented on giant screens during the concert. After the concert, the original score and the 10 paintings will be available in the lobby for closer inspection. Continue Reading "Of Tunes, Tales and Truths -- and The Light Princess" »

Imagine returning to your old college – seeing students learning what you learned so many years ago, maybe even from the same professors, getting the same education you did. Imagine returning to be part of their journey!
That's just what I've been doing for seven years as an adjunct professor at The Master's College
. Obviously, I have the best students in the world, and I love my subjects and the school's commitment to Biblically-based teaching.
The Biblical perspective shapes everything about teaching here, from how the material is presented to how professors engage with the students.

Not long after my Introduction to Robotics course started, it got its very first press coverage!
Three years ago, I was interviewed by Jason Cremeen, a student writing for The Master's Piece, a student publication of The Master's College. What I love about this article is how Jason emphasizes that this course is not an engineering program for computer nerds only -- it's a hands-on critical-thinking course for anyone.

We had a great first session of my Intro to Robotics class
last night at The Master's College! I have 17 upper-division computer science majors, and I think they're even more excited about this course than me!
The students were so engaged last night that I asked them whether they'd like to stay an extra half-hour, and every one of them said yes.
After the lecture, we spent time in the lab building our test robots. It's going to be a lot of fun helping them move from inanimate software development to moving parts!

Starting this evening, I'll be teaching Intro to Robotics at The Master's College once again. I love having this opportunity to teach students critical thinking and problem-solving in a very hands-on way -- by building robots that solve puzzles and attack each other!
I created this course at Master's a couple years ago. At the time, a few students from the College made this (admittedly silly) video to show in Master's chapel to promote the course:
Of course, this video is not wholly accurate. Students never watch cartoons in my class (though they have been known to eat M&M's).
And since we're on the subject of teaching...
Which TMC faculty and staff did you see in the video?
How many different robots were shown?
Bonus: whose lab was this shot in?
I look forward to sharing more about this class!
A fuller description of the course is available at masters.edu.
