Alpha Dog, the Alpha Robot

Robots have been around for several decades doing jobs that human can’t or simply won’t do. At first these robots were used purely for manufacturing but as technology advanced so did robotic potential. Robots are now breaching many sectors including the military. One these robots is Alpha Dog.

Dog is a robot designed by DARPA to carry equipment that the average soldier can’t. Alpha Dogs carrying capacity is approximately 400 pounds for 20 miles; Alpha Dog has to refuel every 24 hours. This year Alpha dog began its first outdoor test, before it was linked to a hydraulic system that confined it indoors.

It remains to be seen whether or not Alpha Dog will be effective in the field. Critics have said that its lack of armor would make it extremely vulnerable.

ROV: Underwater Robotics

When I was four I modeled for a book.  You know those progressive, interactive books for kids?  I posed for the back cover of My Little Blue Robot.  My friend Max and I stood in a hot studio for a few hours playing with this little cardboard robot.  Each page of the book contains a piece and the idea is to put the robot together as you go through the book.

Ever since then I’ve been fond of these little mechanical things.  They’re fun, easy, and don’t (usually) talk back to you.  It’s nice.  And personally, I like to make things in my free time so robotics seemed like an interesting subject.

The summer of 2009, I took R.O.V. at CIMI.  The class description said we could build underwater robots and I decided to try it.  Having no idea what I was getting into, I entered the course completely out of my element and loved it.

R.O.V. stands for Remotely Operated Vehicle.  We made simple ones at Sea Camp and the controls were already wired and ready for us.   All we had to do was make the frame out of PVC pipe and zip tie it together.

I decided to make one for my 8th grade science project.  Not so much for the science part, but just because it was fun to build.  My dad and I measured and cut all the pipe, laid out the dimensions, and glued each piece together.

We gathered a mountain of materials; zip ties, PVC pipe, drills, film canisters, propellers, a control box, piano wireelectrical wire,toggle switches, batteries, glue, scissors, a car battery, wax, wire cutters, wire strippers, screw drivers, rubber bands, an old razor phone, plastic zip lock bags, and food (of course).

This was our work table:
