PING))) Kit for Stingray (#28985)

This kit gives the Stingray Robot the ability to sense its surroundings while in operation; with the addition

of these modules, the Stingray can actively maneuver, avoid, or find objects that could not previously

detected. The 3 PING))) sensors are attached to the front of the Stingray mounting panels giving it a

wide field of view; with various mounting holes you can customize or install the modules in a manor

which best suits the needs of the robot.

Features

 PING))) Ultrasonic Range Finders

 3-pin extension cables for easy

connections

 Nylon spacers to ensure proper

installation on the chassis

 Ultrasonic vision for the Stingray Robot for

up to 9 meters

Key Specifications

 Power requirements: ~60mA @ 5 VDC

(~20mA each PING))) sensor)

 Communication: Positive TTL Pulse

 Operating temperature: +32 to +158 °F (0 to +70 °C)

Application Ideas

 Ultrasonic vision for a robot

 Robotic distance detector

Assembly Instructions

Step 1: Part Verification

Unpack everything from the packages and

make sure you have all the parts and that

you have the tools listed below.

 1 – Built-up Stingray Robot

 3 – PING))) Ultrasonic Range

Sensors

 6 – 4/40 Zinc nuts

 6 – 4/40 1/2” zinc pan head scre ws

 6 – 3/16” #8 Plastic Spacers

 3 – 10” Extension cable

 6 – Nylon Washer #4

 3 – Rubber Grommet

 1 – Parallax screw driver *

 1 – 1/16” Hex Key *

Note: Tools indicated with a * are provid ed

in the Stingray Robot Kit and not included in

the PING))) Kit.

Step 2: Disassemble

Using the 1/16” Hex key that came with the

Stingray Robot kit; start by unscrewing the

front sensor mount plates, hereafter referred

to as plates or plate.

Each plate will have 4 screws connecting to

the chassis, two on top and two on bott om.

Once removed, keep these screws in a

secure place.

Once all 3 plates are out, you should h ave a

total of 12 screws as well as 3 lose front

plates.

Step 3: Connecting Cable

Connect a10” extension cables to the

PING))) sensor. The pins on the module

should be connected to the cable as

followed:

Black connects to GND

Red connect to 5V

White connects to SIG

Place a rubber grommet in the circular area

of plate and insert the connection cable

through the grommet.

If in step 4 you chose to install the PING)))

in a different orientation, it is suggested that

the grommet be still used to protect the

cable from getting damaged.

Step 4: PING))) Sensor Assembly

Place the nylon spacers as pictured to align

the PING))) sensor. It is possible to install

the sensors in various place s on the plate,

the middle was chosen for versatility;

however if the PING))) sensors are inst alled

to close to a surface, they are likely to

encounter false echoes.

Using a screw, nylon washer, and hex nut;

connect the PING))) module to the plate. Do

not tighten the screws all the way until you

have adjusted the PING))) to make sure it is

being installed straight.

Once you have installed the PING)))

module, the plate should look similar to the

one pictured.

Step 5: Repeat (x 2)

Once you have completed the first plate,

use the previous step to build the other two

plates. When you are finished with this step,

you should have 3 sensor mount plates that

look similar to those pictured.

Step 6: Sensor Mount Plate Re-Assembly

You can use the circular cutout on the top of

the Stingray to route the cables to connect

to the I/O pins.

Note: Remember which PING))) uses which

cable; the white wire of the cable will

connect to an I/O pin in step 8.

Using the same screws from step 2,

connect plate back on the Stingray.

Note: When connecting the plate, do not

tighten the screws until all 4 are in; this will

installing the sensors straight easier.

Step 7: Repeat (x 2)

Connect the other two plates in the same

manner as the first.

Once completed, you should have no ex tra

screws and the robot shou l d look similar to

this example.

Step 8: Connecting PING))) to I/O

With the Stingray oriented so that the

PING))) modules are facin g away from you;

the numbering goes as followed:

Left PING))) to I/O pin 0

Center PING))) to I/O pin 1

Right PING))) to I/O pin 2

Step 9: Download Samples

Download PING)))s on a Stingray robot -

Archive (.zip ) from the Downloads and

Resources area on the product page, item

code #28985.

Save all 3 files. Once the zip is extracted to

a folder, open Stingray Demo.spin; this is

the top level program leaving PING))).spin

and PWMx8.spin as the object files.

Step 10: Turn On & Run Program

Turn the Stingray power switch to POWER

ON/MOTORS OFF.

Download the top level program (Stin gray

Demo.spin) to the Propeller by pressing F11

or selecting run => compil e current => Load

EEPROM.

The Stingray is ready to roam.

Device Information

Theory of Operation

The demo program displays how the Stingray can avoid obstacles using the ultrasonic sensors. The

Stingray can maintain a course of forward progress and can be programmed to perform a various number

of other tasks while still keeping the proper distance; if stuck in a corner or similar type obstruction then

the Stingray will spin while finding the best option. Once you have verified that everything works and is

functional; continue and enjoy creating your custom applications.

Precautions

 Do not rely solely on the PING))) sensors to see an object to halt operation; if you feel there is

any way of possible damage to either the robot or bodies, please exercise extreme caution while

using the Stingray Robot. If you have any question s, feel free to contact technical support to get

any questions answered.
