Hardware and technical overview
Sentio OS is software. You can buy it on its own for your own computer, or as a ready-made backpack where everything is wired up and tested. This page explains what Sentio is technically and what you need for it.
What Sentio OS is
A single Docker container image for the arm64 architecture. Installing means pulling the image and starting it; nothing is compiled and no dependencies get scattered over the system. The image runs three services:
- web — the complete browser-based control on port 8000 and the API
- vision — cameras, object and AprilTag detection, localhost only
- speech — Piper text-to-speech on the device itself, no cloud
It talks to the robot over DDS on the wired network 192.168.123.0/24, which is why the containers share the host network. Your data, scenarios, black-box records and licence stay in a directory on disk, not in the image.
Runs without internet
Control, speech, vision and the licence check are all local. Internet is only needed to download updates and for optional cloud services.
One-command updates
./sentio aktualizuj
downloads the new version and switches to it. If it doesn't start, it rolls back to the previous one by itself.
The robot stays untouched
Sentio runs alongside the robot's original software and doesn't overwrite it. It can be switched off at any time and the robot works as before.
How to get Sentio
Sentio Backpack
A ready-made kit the robot carries on its back: a Jetson Orin Nano Super computer, power from the robot's battery, camera, Sentio gripper and installed, tested software. The free version works right away; the Sentio licence is ordered separately for the backpack's device ID.
- arrives wired up and tested, nothing to assemble
- one party responsible for both hardware and software
- the gripper is our own device and is matched to the backpack
EUR 2,990excl. VAT · kit, licence separate
Additional grippers and other quantities on request.
Licence only
If you have your own computer, you buy just the software. The Sentio licence is annual, belongs to a specific device and unlocks everything Sentio can do.
- for the second computer inside the G1 robot (Jetson Orin NX)
- or for your own board meeting the requirements below
- manual control and robot care are free and never expire; you can try Sentio for 14 days
EUR 5,900excl. VAT · robot / year
Valid for a year from issue, updates included. If you don't renew it, the free version remains after a 30-day grace period and nothing is deleted.
The order is deliberate: you install the software first, it shows you the device ID in Settings, and only then do you order the licence with it.
Pricing
| Item | Price excl. VAT | Note |
|---|---|---|

How much space Sentio takes
| Item | Size | Note |
|---|---|---|
| Download from the registry | 0.83 GB | compressed image, once; updates only download changed layers |
| USB stick package | ~1 GB | offline installation: image, voices, detection model, installer |
| Unpacked image | 3.7 GB | space used on disk |
| Voices and detection model | 0.19 GB | Czech and English voice, object detection |
| Data and black box | up to 1.5 GB | fixed cap, older records are deleted automatically |
| Recommended free space | 16 GB | fits two versions side by side for rollback |
The first installation takes minutes, depending on your connection. Updates are faster because only changed layers are downloaded.
Your own hardware: what the board needs
- 64-bit ARM processor and Linux with Docker
- at least 8 GB RAM. With the arm and detection running at the same time, 16 GB is more comfortable
- NVMe disk from 64 GB. An SD card is slow and the black box wears it out
- wired Ethernet for the connection to the robot, ideally two ports: one for the robot, one for the network
- two or more USB 3 ports for the RealSense camera, gripper and microphone
- power from the robot's battery via a 48 V converter
Sentio doesn't need a GPU today, so boards without NVIDIA are an option too.
Specific boards
Verified means Sentio runs on it in our lab. For the others we are confident about the requirements but don't operate them ourselves. Write to us first so we can confirm it makes sense for you.
| Board | Cores, RAM | Status | Note |
|---|---|---|---|
| Jetson Orin Nano Super | 6 cores, 8 GB | verified | today's Sentio backpack |
| Jetson Orin NX | 8 cores, 16 GB | verified | second computer inside the G1 robot |
| Seeed reComputer J30/J40 | Jetson Orin in an enclosure | will run | cooling and NVMe included |
| Jetson AGX Orin | 12 cores, 32–64 GB | will run | expensive and power-hungry, overkill for a backpack |
| Orange Pi 5 Plus (RK3588) | 8 cores, up to 32 GB | should run | two Ethernet ports and NVMe |
| FriendlyElec NanoPC-T6 (RK3588) | 8 cores, up to 16 GB | should run | two Ethernet ports, compact |
| Radxa ROCK 5B+ (RK3588) | 8 cores, up to 32 GB | should run | NVMe on the board |
| Radxa ROCK 5 ITX (RK3588) | 8 cores, up to 32 GB | should run | better for stationary use than on the back |
| Raspberry Pi 5 | 4 cores, 8–16 GB | with tweaks | cheapest, see below |
| NXP i.MX 8M Plus boards | 4 weak cores | borderline | manual control yes, arm and detection will be slow |
Outside Jetson, for a backpack we would try RK3588 with two Ethernet ports, i.e. Orange Pi 5 Plus or NanoPC-T6. They are closest to the Orin Nano in performance, and one port goes to the robot, the other to the network.
Raspberry Pi 5: a standard installation with three tweaks
A regular system is enough — 64-bit Raspberry Pi OS or Ubuntu — plus Docker. Keep the following in mind:
- Kernel with 4 kB pages. The Pi 5 boots a kernel with 16 kB pages and some ARM programs in Docker
crash on it. It is fixed with one line in
/boot/firmware/config.txt:kernel=kernel8.img
We don't know yet whether Sentio really needs it, but it is the most common Docker problem on the Pi 5. - NVMe disk via the M.2 HAT+; the board has no connector of its own.
- 5 V / 5 A power via a converter from the robot's battery. The RealSense camera draws extra current over USB.
