She never has to press anything.
A wearable that reaches someone she trusts, in seconds, without her having to say a word. It listens on the device for threatening language and distress. When it fires, the parent and the school get a WhatsApp alert with her location, and the guardian can listen in live.
No button · no screen · no speaker · in development at Travis Labs, Lusaka
Harm happens where adults cannot see or hear.
At home, in transport, in school corridors. The youngest children often cannot explain what is happening to them, and today’s response begins after the harm. Abby is built to close that gap: a guardian on the child, not just on the bus.
Light enough to go unnoticed.
On the wrist. Nothing to press.
A slim capsule curved to the wrist, with a prismatic cell and a single amber status line. No button, no screen and no speaker, so there is nothing for the child to operate and nothing to draw attention. Design target: 42 × 20 × 5.5 mm.
On the uniform or the bag. With an SOS key.
The same listening intelligence in a clip for uniforms and school bags, with a lanyard loop and an SOS key for older children who want to raise the alarm themselves.
From sound to safety in seconds.
It listens. It does not record.
Analysed on the device
Audio is processed inside Abby. Nothing is stored on it, and no audio leaves it.
Only two things go out
A location message when trigger words fire, and a live call that the guardian answers.
A microphone, no speaker
By choice. No adult can talk to a child through Abby.
Built for Zambia’s law
Designed around the Data Protection Act (2021), with trained models per region: Lusaka and the Copperbelt first, in English, Nyanja and Bemba.
Route43 protects the school run. Abby protects the child.
Route43 gives schools a QR tag per child, offline scanning at pickup and drop-off, WhatsApp live links for parents and an office dashboard for every bus. Abby extends that to the moments between the stops: the walk home, the corridor, the house. Same tag, same links, same login, now with a guardian on the child.
Location is the start. Listening is the point.
Imported GPS watches track location only, need a smartphone app and know nothing about the school. Abby listens, needs no phone for the child, and lives inside the system the school already runs.
AI
On-device intelligence that listens for harm.
Biometric
A second read on distress.
Beacon
Her location, shared with the people who matter.
Young
Made for the youngest learners, who are too young for a smartphone.
Designed on a bench that has shipped real hardware.
Abby comes from the same Lusaka bench that reverse-engineered a discontinued control card for Lusaka Water and now exports self-designed electronics. Abby is in development: next come a working unit, pilots with schools and type approval before any sale.
What parents and schools ask.
What is Abby?
Abby is a child-safety wearable from O’Sense and Travis Labs, the hardware division of HERO Control Systems in Lusaka. It listens on the device for threatening language and distress, and alerts the parent and the school with the child’s location.
Does the child have to press anything?
No. Abby Band has no button, no screen and no speaker. It listens on its own. Abby Clip, for uniforms and bags, adds an SOS key for older children who want one.
Does Abby record children?
No. Audio is analysed on the device and is not stored. Only two things leave it: the location message when trigger words fire, and a live call the guardian answers.
Does a child need a phone?
No. Abby works without a smartphone, which makes it right for the youngest learners. Guardians get alerts on WhatsApp.
Does it work where there is no mobile network?
Abby uses LTE where there is coverage and LoRa as a fallback where the network fails.
How does Abby connect to Route43?
Abby is the hardware layer of Route43, the O’Sense school-transport app. Alerts reach the same WhatsApp links and school dashboard parents and schools already use.
Is Abby available to buy?
Not yet. Abby is in development at Travis Labs. Schools and parents who want to be part of the pilot can message us on WhatsApp.
Every child deserves to be heard.
