robot top deck kit is a 17.875” diameter high density
polyethylene plate with all the mounting hardware required
to attach it and add additional decks. It is also easy to drill
and customize. It sports built-in handles to make it easy to
lift the robot up.
Sensing Your Environment
There are too many sensors to list here that could be
used with the Arlo, however, I will cover the options that are
already built into the platform. The Arlo base is pre-drilled to
fit some sensors with stands provided by Parallax. There are
positions for up to 10 of these sensors, and you can mix
and match. You also don’t need to fill all the positions; they
are just there for maximum coverage. The first option is the
PING))) ultrasonic sensor and protector stand. These are
aluminum and include the hardware for mounting. There is
also an acrylic stand available (hardware included), though
you would need to buy the PING))) sensor separately. If
you’re looking to mix ultrasonic and infrared sensors for
more reliability, Parallax offers the dual PING)))/IR acrylic
stand with sensors. This sensor combines the power of the
PING))) sensor with the Sharp IR distance sensor.
I Got the Power
If you recall at the beginning of the article I mentioned
an option being added that was not ready at press time.
Until recently, tying all the power connections together was
quite a task and required a lot of connectors to do so. The
new Arlo power distribution board will make things much
easier for the customer.
