Nosy Monster… & Pals!

The Nosy Monster was revamped and given a couple of friends for the occasion of the 2019 Thayer School of Engineering Open House.

Introducing: Nosy Monster,  Croc Dundee, and Later Gator

The idea of piloting a rover through a maze happened serendipitously last year, as a cobbled together Nosy Monster driven by relays was an extra to the booth I was running. I figured it’d run until it broke and that’d be that. It turned out to be very popular when I realized I could throw it in the messy room next door and send it “to Mars”. Kids had a blast and it was a huge hit.

I improved handling further this year by purchasing a few L298Ns. These things are the best thing since sliced bread. I still intend on documenting the build at some point in the near future. The rovers gained speed control, back direction, and much better turning.

Keeping with what we know works well, we built an actual Mars themed maze in a messy room

No pictures from the event unfortunately, it was just too busy.

I just have to post

This Dragon which found its way into the Mandalagaba digest. I haven’t seen anyone really touch recursion yet, and then this shows up.

This is my absolute favorite thing about adding features to Mandalagaba: seeing them used in ways I didn’t even realize were possible. Here recursion is used to create ethereal traits. Of course mirror symmetry is used for the face too but that I had seen before :). The hours spent hammering out recursion are all of a sudden, absolutely worth it.

Recursive Drawing is out

It’s only available on the “pro” facet of Mandalagaba. Oh yeah, Mandalagaba has been broken down into several facets for the purpose of simplifying and focusing activities. The facet where all the brain hurting stuff goes is the pro one. Pro is where one can draw a “radially symmetrical tessellation recursively”.

I tried to keep the menu simple and icon based but it’s still the most complex. Thankfully we have words to describe all that these things do.

Along with recursion, is out too, using recursion, symmetries and a newly developed center placement to create plants & trees. This one still needs a bit of polish but the main idea is working. I touched a lot of the core engine of Mandagaba to introduce all this, development went pretty well. It was nice to test the flexibility I gave myself during last Winter’s rewrite for a major feature add.
