Introduction
The Wireless Smart Cart is a combination wireless
USB device that connects to a computer or tablet
through Bluetooth® (version 4.2 or later), or to a
computer or USB charger with a micro USB cable
(included). The Smart Cart has a durable ABS body, a
three-position plunger, and nearly frictionless wheels. It
includes built-in sensors that measure force, position,
velocity, and three degrees of freedom in acceleration.
The Smart Cart also includes a gyroscope-type sensing
element that can measure rotational motion. The Smart
Cart can make its measurements on or off a dynamics
track and transmit them wirelessly. For easy identification, the Smart Cart is available in red or blue.

The Smart Cart is designed by PASCO
in California and assembled in China.
The accessory tray on the top of the Smart Cart can hold
any of the accessories designed for a PASCO cart. The
Smart Cart dimensions are the same as other PASCO
carts and can be used with any PASCO track. The
Smart Cart can be stacked with any PASCO cart and its
mass is approximately 0.250 kilograms (about 250
grams). It has attachment points on the top and bottom
of both ends, and Velcro® tabs for inelastic collisions on
one end. The Magnetic Bumper, Bumper Attachment,
and Hook Attachment fit into the threaded hole in the
end of the Smart Cart opposite to the tabs.
The built-in sensors measure force in the range between
-100 newtons (N) and +100 N, acceleration in the range
between -16g and +16g (g = ±9.8 m/s
2
), and angular
rotation rate up to ±245 degrees per second (dps). It
measures force as a push or pull along its X axis and
measures acceleration in three dimensions (X, Y, and
Z). The PASCO Data Collection Software can also show
the resultant acceleration. The encoder wheels on the
Smart Cart measure motion to a maximum of 3.0 meters
per second with a resolution of 0.2 millimeters (mm).
The positive direction of motion is the same as the
X-axis in the graphic that represents the acceleration
sensor’s position

The Smart Cart is designed to optimize the battery
usage time. Since each Smart Cart has a unique Device
ID number, more than one can be connected to a
computer or tablet at the same time.

Initial Step: Charge the Battery
• Connect the Cable: Use the Micro USB Cable to
connect the micro USB port on the Wireless Smart
Cart to a USB port or USB charger such as the
PASCO PS-3501 USB Charging Station. Charging
begins automatically. The charger circuit inside the
Smart Cart turns itself off when the unit is fully
charged. The battery status LED will shine yellow as
the battery is charging, and will shine green when
the battery is charged. The battery is partially
charged at the factory. Initial charging time may be
three hours or longer depending on the power
source and the condition of the battery.

Zero (Tare) the Smart Cart
At the beginning of an experiment, the measurement
from the built-in force and acceleration sensors may not
be zero when the force or acceleration is actually zero.
This is a normal behavior that is corrected when you
zero (or tare) the sensor using the PASCO Data
Collection Software. See Appendix B for information
about setting the built-in sensors to zero.
Collect Data
• In the SPARKvue Home Screen, select a
measurement from the list under the sensor’s name.
A graph of the measurement versus time opens.
• In SPARKvue, select the Start button ( ) to begin
collecting data.

setting up the software:
Collect Data
• In PASCO Capstone, select a display in the main
window or from the Display palette. In the display,
use the <Select Measurement> menu to pick a
measurement to be shown.
•Select Record to begin collecting data.
Troubleshooting the Wireless Smart Cart
• If the Wireless Smart Cart loses Bluetooth
connection and will not reconnect, try cycling the ON
button. Press and briefly
status LEDs blink in sequence, and then release the
button. Start the Smart Cart in the usual way.
• If the Smart Cart stops communicating with the
computer software or tablet application, try
restarting the software or application. If the problem
remains, press and hold the ON button for 10
seconds and then release. Start the Smart Cart in
the usual way.
