After three years and thousands of FindBall sensors now being used around the world, it was time that we refreshed the products available and made space for new products later this year.

When TRIS10 robotics started, the aim was, and still is, to provide products not readily available elsewhere, especially in the educational robotics market. As such, products such as the TrackMotion IMU sensor, KickBall devices and the ProtectCircuit power supply no longer align with this aim - compared to in 2014, IMUs are readily available, easy to use, and no longer break the bank. By no longer actively selling these products, we can focus on developing new and exciting products in 2017. We'll have more information on these new products later this year.

We'd like to thank all of our customers for their ongoing support since TRIS10 ROBOTICS started. We've shipped to users across the world - from Austria to more…

It has taken longer than expected, but we are pleased to announce we now have a greater range of mini blade fuses available: both the 3A and 7.5A versions are now available. Like all of our ProtectCircuit fuses, they light up if the fuse blows, so you can easily see when something goes wrong.

The 10cm ConnectNXT cables - they're red!

When working with the NXT and EV3 platforms, one of our biggest annoyances was the long NXT/EV3 cables that got in the way. We found that 10cm and 15cm cables were the ideal lengths for most robots, so we made them. We now have packs of 5 and packs of 20 of each length available for sale.

Unlike some other cables available, these NXT/EV3 cables have proper insulation, and in keeping with the brand, they're even red! They also have the correct colour coding of each wire and high quality connectors, making them durable and easy to use.

We have just received a large shipment of Vishay TSOP31140s for our FindBalls, and we now have enough stock to make them available for sale. The TSOP31140s are the sensors used in our FindBall sensors to detect and lock on to the ball. They are 40kHz infrared receiver sensors that have a digital output and are ideal for detecting the RoboCup Junior soccer ball. The TSOP31140 is identical (in all ways) to the deprecated TSOP1140.

We are selling the TSOP31140s in two pack sizes: packs of 5 and packs of 50. We are pleased to say that our prices are up to 80% less than that of of other electronics stores and we look forward to seeing the custom soccer robots and other systems that utilise these sensors. For those looking for an easier to use system with onboard signal analysis, more…

Xander Soldaat, of Bot Bench (and RobotC driver) fame, has written an excellent article about the FindBall and EmitIR devices. The article also includes lots of photos of his teardown of the sensor, showing both the structure of the case and the electronics. Following his suggestion of changing the pin alignment, we have modified the case to make the pins an odd number of spaces apart, so the sensor is easier to center. All FindBalls now being sold have this case.

He's also written a RobotC driver for the FindBall for us, which makes interacting with the sensor really easy, and has included it in the RobotC third-party driver suite. The sample programs included in the driver suite show how to read all of the important registers. To read the best sensor and its strength using his driver, it's just more…

This is the second of four posts that will demonstrate using the FindBall NXT (or FindBall Open) with a LEGO® NXT, a LEGO® EV3, an NXT and RobotC, and an Arduino. This post covers how to use the FindBall with an Arduino, or similar microcontroller. A FindBall Open has an easily accessible header on it for connections, however to use a FindBall NXT, a ConnectNXT Breakout is required.

Wiring it up

Arduino and FindBall wired up for testing

Although the photo above shows a FindBall NXT, a FindBall Open can also be used just by using the header connections on the FindBall PCB. The connections have the same names.

FindBall Open / ConnectNXT Breakout Arduino
Vcc 5V
GND GND
SDA SDA (normally A4)
SCL SCL (normally A5)

On recent Arduinos the internal pull-ups are fine, however on other microcontrollers, external 10k pull-up resistors should be used on the SDA and more…

It's been one week since we launched and we've been busy building up our stock levels and working on more blog posts demonstrating our products (coming soon). We haven't stopped making new products though and we are happy to announce the newest product: TrackMotion.

The TrackMotion is a nine-axis Inertial Measurement Unit (IMU) based on the MPU-9150 by Invensense. It has an on-board accelerometer, gyroscope and magnetometer that provide very accurate readings at up to 1000Hz. By combining all three sensors, you can often avoid the compass calibration issues that plague soccer robots. As each sensor is three-axis, the TrackMotion can also provide motion data on the X- and Y-axes as well, which is useful for other robots like UAVs. The TrackMotion has an I2C interface and operates at 3.3V (this version is not 5V tolerant).

We have more products in the pipeline that we hope more…

FindBall NXT Example NXT Robot

This is the first of four posts that will demonstrate using the FindBall NXT (or FindBall Open) with a LEGO® NXT, a LEGO® EV3, an NXT and RobotC, and an Arduino. This post covers how to use the FindBall with the LEGO MINDSTORMS NXT software. The FindBall NXT is also fully compatible with an EV3 and the LEGO MINDSTORMS EV3 software. To use it on an EV3, just use the EV3 ultrasonic block that is available for download.

To demonstrate the FindBall NXT, we built and programmed an NXT to chase the standard RoboCup Junior (RCJ-05) soccer ball in RCJ pulsed mode (Mode A). To keep it simple, the program is the bare minimum and there are a number of changes we can think of that would make it faster and smoother.

The Robot

Welcome to TRIS10 ROBOTICS, an Australian robotics and electronics business. After nearly one year of extensive development and prototyping, we are extremely proud to launch our initial product line and our new website.

After gaining years of experience competing in the RoboCup Junior competitions nationally and internationally as part of team TSR, we found there was a significant gap in the market for products designed for use in RoboCup Junior, especially above the introductory level, and we realised this was a serious shortfall. We wanted to lower both the cost and level of experience needed to participate in robotics so that more schools, more teams and more people could get involved. To achieve this, we analysed what many teams needed and worked with them to develop and provide the best products for the competition, without limiting the learning experience (that is why we provide many as unassembled kits). more…
