PASCO Wireless Smart Cart Overview


[PASCO Wireless Smart Cart Overview] Brett: Hi, this is Brett Sackett and… J.J.: J.J. Plank. B: …with PASCO scientific. We’re here today to tell you about the PASCO
Wireless Smart Cart. J.J., Let’s have a look at this. J: All right! B: The Smart Cart comes with some accessories. We’ll talk about those in a little bit. Let’s talk about features of the Smart Cart. The Smart Cart is wireless. It has internal
sensors. The sensors are an encoder on the wheels that’s going to give us position, velocity,
and acceleration. And you can use those measurements on a track
or off a track. There’s also a force sensor on the front of
the cart here. It’s a plus or minus 100 N load cell. There is an internal accelerometer. It’s a
three-axis accelerometer and gyro, so we can get linear accelerations in all
three directions, we can get the resultant of the acceleration,
and also rotations. Now going around the cart on the front there’s
the plunger you expect, and it’s easy to lock, easy to load. There’s the Velcro tabs, and then there are tie points around the cart
so you can tie string, like if you’re going to do a mass over a pulley and you want to pull the cart that way you
can do that. At the top of the cart there’s a mass tray
for changing the mass of the system. Then also this cart you can get in red and
also blue, so when you’re doing conservation of momentum
experiments you can tell the two carts apart. There’s an internal rechargeable battery, and this cart is of course compatible with
all of PASCO’s cart accessories. So this really is PASCO’s legendary low friction
cart, reimagined for the modern physics lab. J.J., let’s hook it up. J: Before we get this guy connected, let’s talk a little bit about what came in
the box with the cart. There are four little pieces that came with
it, four accessories. One of them is a USB charging cable. So inside the Wireless Smart Cart is a rechargeable
battery. We’re going to keep that guy connected when
we’re not using it. In addition to that, we’ve got three accessories that we can mount to the force sensor that’s
on our Wireless Smart Cart. Two of these here you’ll see they look familiar: they’re the same accessories that come with
the PASCO force sensors currently. One is a rubber bumper, and the other is a
metal hook. Like I said, all of them can mount to the
front of the cart just like it mounts to the front of our force
sensors. Then a third and a new accessory is a magnetic
bumper that we can also mount to that force sensor, and we can use that magnetic bumper for experiments
in collisions, or conservation of momentum, and stuff like
that. Now that we know a little bit about the cart’s
sensors, and a little bit about the cart’s accessories, let’s take a look at how we connect the cart
to our software. The Wireless Smart Cart’s onboard sensors can connect to either SPARKvue software or Capstone software. For this purpose we’re going to be using PASCO
Capstone software. I’m going to go ahead and fire up the software
on my computer. Brett, would you mind firing up one of the
Smart Carts? B: On this side of the Smart Cart there is
a power button, there is an accessory port here for optional
Smart Cart accessories, and then the USB charging port. J: Once the cart’s turned on it starts broadcasting
via Bluetooth 4.0 Low Energy, and that’s a very useful tool for this purpose
because it allows the Bluetooth connection between the computer and the Wireless Smart
Cart itself to be very simple. In this software all we do is open up our
Hardware Setup window, like you see here. It lists the Bluetooth devices here under
that Available Wireless Devices heading. All you do is just click once and then it
connects via Bluetooth to that Wireless Smart Cart. B: What’s great about this is this is in app
proximity pairing, so you don’t need to go through the operating
system’s Bluetooth settings. It’s right in the software. J: You see here there are three sensors. These are those three onboard sensors that
Brett was mentioning. Once the Wireless Smart Cart is connected,
it talks to the software just like any other sensor does. I’m going to create three graph displays, and we’re going to take a look at the position,
velocity, and acceleration measurements made by the cart. We’ve got that, I’m just ahead going to go
ahead at click Start here, and roll that cart over there to Brett. B: I’m going to roll it back. J: As we know, the cart uses a motion encoder
and it can work on a track or off a track, just like this. B: So that’s the introduction to the PASCO
Wireless Smart Cart. Thanks for watching. If you’d like more information, go to www.pasco.com/smartcart.

  1. Thank you for this video. It's very helpful.
    If I buy enough carts for my classes, is the Wireless Force-Acceleration Sensor then still useful, or could I also do other force measurements with the carts?
