Robot Game Animals Catch Poachers

Hobby crossover alert! I found this National Geographic News article about robot deer, grizzlies, turkeys, moose (meese?), being used to catch poachers. (Picture is from the original article, given to NGN courtesy Custom Robotic Wildlife)

One of my other hobbies is hunting, so it is kind of neat and inspirational to find these hobby crossovers where someone is making the world a little bit better place.

Robotics Books

I saw a post on one of the robotics mailing lists that got me to thinking... I don't think I've ever mentioned what robotics books I like. Here's the list below. I created a Bot Thoughts Bookstore in case you want to order some of these from Amazon. :) :)
  • Intermediate Robot Building - Cook : lots of great explanation and circuits, some programming
  • Applied Robotics - Wise : programming, basic AI, circuits, mechanics
  • Insectronics - Williams : focused on building a walking robot; ideas for sensors
  • Mobile Robots: Inspiration to Implementation - Jones, Flynn : wide array of topics with a little more of the academics behind it all
  • 123 Robotics Experiments for the Evil Genius - Predko : literally 123 different things you can do robot-wise; the first few dozen are super basic, and it builds from there
  • Robots, Androids, and Animatrons - Iovine : some good inspiration but no technical detail
Anyway, hope this helps you on your robotics journey!

Squeaky - not forgotten

Squeaky < prev | next >
I haven't forgotten about Squeaky, the Record Cleaning Robot... hope you haven't either. Since I have about 500 records give or take 100, I have plenty of records I can use to practice manual cleaning. There's no worrying that I'll be done cleaning my collection anytime soon.

Now that I am getting the right technique figured out, I can start to design the robot. I figure the best approach is to build the machine to operate manually and add on the automatic controls a little at a time.

I'm using a small handheld vacuum similar to the one pictured. It comes with an extension hose and various attachments, one of which is wide enough to cover all the LP tracks. I wrap a microfiber towel around it to prevent scratching the LP surface. When it comes time to build the real thing, I'll create my own nozzle attachment and mount it on a moveable arm that will eventually be actuated by servos.

To apply cleaning fluid I am using a small discwasher squirt bottle. This will be replaced by a sprayer from a garden drip system, powered by a spare 12V car window washing fluid pump I have on hand (means I need to build another DC power supply).

I'll mount the sprayer on another arm that is servo controlled. Or maybe I will try to mount it to the same arm as the vacuum fitting. Not sure yet.

Before vacuuming and after applying fluid, I lightly hold a paint edger pad against the wet record to "scrub" and will do something similar with Squeaky, mounting an edger on the sprayer arm.

At least that is the plan so far.
