Apa ini

Unitree.Net memberi aplikasi .NET akses penuh ke robot Unitree — kuadruped (Go2, B2) dan humanoid (G1, H1, R1) — mulai dari perintah torsi per-motor pada 500 Hz sampai navigasi waypoint dan antarmuka bahasa alami.

Format kabel (wire format) diimplementasikan ulang di C# dan diverifikasi byte-per-byte terhadap tata letak struct C++ Unitree, sehingga CRC yang dihitung SDK ini persis sama dengan yang dihitung firmware. Ini penting: firmware membuang perintah dengan CRC salah tanpa pesan error apa pun.

Instalasi

dotnet add package Unitree.Net

Paket Unitree.Net adalah paket payung: ia menarik seluruh SDK sekaligus. Kalau hanya butuh sebagian, pasang paket per-modul saja (lihat tabel di bagian Packages).

Unitree.Net.Ml sengaja tidak ikut dalam paket payung — ML.NET dan TorchSharp membawa ratusan megabyte runtime native, dan hanya aplikasi analisis gait atau lokomosi hasil pembelajaran yang memerlukannya:

dotnet add package Unitree.Net.Ml

Untuk berbicara dengan firmware robot sungguhan masih dibutuhkan native shim Cyclone DDS, yang dibangun terpisah dengan CMake — lihat native/README.md. Transport murni-managed bawaan SDK hanya bisa bicara dengan simulator.

Mulai cepat

Tidak punya robot? Jalankan simulator dulu — ada tampilan 3D-nya, dan telemetrinya sungguhan:

dotnet run --project apps/Unitree.Net.Simulator          # simulator 3D (Windows)
dotnet run --project samples/Unitree.Net.Samples.VirtualRobot   # versi headless

Lalu di terminal lain:

dotnet run --project apps/Unitree.Net.Cli -- status     # snapshot telemetri
dotnet run --project apps/Unitree.Net.Cli -- monitor    # dashboard langsung
dotnet run --project apps/Unitree.Net.Dashboard         # dashboard web

Mau langsung bikin aplikasi robot? Buka Unitree Robot Wizard — editor kode dengan 16 template yang semuanya jalan di simulator tanpa perlu diubah:

dotnet run --project apps/Unitree.Net.Wizard

Perintah pertama yang harus dijalankan kalau robot "tidak terhubung":

dotnet run --project apps/Unitree.Net.Cli -- diagnose

Perintah ini tidak memerlukan robot dan langsung menunjukkan penyebab paling umum: interface jaringan salah, native library belum dibangun, atau multicast diblokir.

Contoh kode

var services = new ServiceCollection();
services.AddUnitreeRobot(configuration);

await using var provider = services.BuildServiceProvider();
var robot = provider.GetRequiredService<UnitreeRobot>();

await robot.ConnectAsync();
await robot.Sport.StandUpAsync();
await robot.Sport.BalanceStandAsync();

// Stream mengirim ulang perintah 20 kali per detik — robot meng-expire perintah kecepatan sekitar
// setengah detik setelah menerimanya. Kalau proses ini mati, request berhenti dan robot ikut berhenti.
using VelocityStream stream = robot.Sport.StartVelocityStream();
stream.Command = new VelocityCommand(Forward: 0.4f, Lateral: 0f, YawRate: 0.2f);

await Task.Delay(TimeSpan.FromSeconds(3));
stream.Stop();

Fitur

Perkakas

Semua template di wizard sudah diverifikasi bisa dikompilasi:

dotnet run --project tools/Unitree.Net.TemplateCheck

Keselamatan

Robot ini berbobot puluhan kilogram dan bergerak di ruang nyata. Beberapa hal yang dibangun ke dalam SDK:

• Envelope keselamatan membatasi kecepatan, torsi, gain, dan laju perubahan setpoint per tick.
• Stream kecepatan menjaga perintah tetap mengalir; kalau proses mati robot berhenti sendiri.
• Deteksi jatuh dan batas suhu motor memicu emergency stop yang terkunci.
• Fungsi gerak untuk LLM dinonaktifkan secara default — harus diaktifkan secara sadar.

Baca docs/safety.md sebelum menjalankan kontrol low-level.

Dokumentasi

Dokumentasi lengkap ada di docs/, termasuk simulator dan Robot Wizard.

PROGRESS.md sengaja memisahkan "build dan test lulus" dari "tervalidasi di hardware". Belum ada yang dijalankan di robot sungguhan.

What this is

Unitree.Net gives .NET applications full access to Unitree robots — quadrupeds (Go2, B2) and humanoids (G1, H1, R1) — from per-motor torque commands at 500 Hz up to waypoint navigation and a natural-language interface.

The wire format is reimplemented in C# and verified byte-for-byte against Unitree's C++ struct layout, so the CRC this SDK computes is exactly the one the firmware computes. That matters: the firmware discards a command with a bad CRC without reporting anything at all.

Installation

dotnet add package Unitree.Net

Unitree.Net is an umbrella package that pulls in the whole SDK. Install the individual packages instead if you only need part of it — they are listed under Packages below.

Unitree.Net.Ml is deliberately not part of the umbrella: ML.NET and TorchSharp bring hundreds of megabytes of native runtime with them, and only applications doing gait analysis or learned locomotion need it.

dotnet add package Unitree.Net.Ml

Talking to real robot firmware also needs the Cyclone DDS native shim, which is built separately with CMake — see native/README.md. The pure-managed transport that ships in the box reaches the simulator only.

Quick start

No robot? Start the simulator first — it has a 3D viewport, and the telemetry it publishes is real:

dotnet run --project apps/Unitree.Net.Simulator                  # 3D simulator (Windows)
dotnet run --project samples/Unitree.Net.Samples.VirtualRobot    # headless equivalent

Then, in another terminal:

dotnet run --project apps/Unitree.Net.Cli -- status     # one-shot telemetry
dotnet run --project apps/Unitree.Net.Cli -- monitor    # live dashboard
dotnet run --project apps/Unitree.Net.Dashboard         # web dashboard

To start writing a robot application, open the Unitree Robot Wizard — a code editor with 16 templates, every one of which runs against the simulator without edits:

dotnet run --project apps/Unitree.Net.Wizard

The first thing to run whenever a robot "won't connect":

dotnet run --project apps/Unitree.Net.Cli -- diagnose

It needs no robot and immediately distinguishes the three usual causes: the wrong network interface, a missing native library, or filtered multicast.

Example

var services = new ServiceCollection();
services.AddUnitreeRobot(configuration);

await using var provider = services.BuildServiceProvider();
var robot = provider.GetRequiredService<UnitreeRobot>();

await robot.ConnectAsync();
await robot.Sport.StandUpAsync();
await robot.Sport.BalanceStandAsync();

// The stream resends the command at 20 Hz, which is what keeps the robot going — it expires a
// velocity about half a second after receiving one. If this process dies the resends stop and so
// does the robot. Pass commandTimeout when the command's source is remote and can vanish.
using VelocityStream stream = robot.Sport.StartVelocityStream();
stream.Command = new VelocityCommand(Forward: 0.4f, Lateral: 0f, YawRate: 0.2f);

await Task.Delay(TimeSpan.FromSeconds(3));
stream.Stop();

Packages

Tools

Every wizard template is verified to compile:

dotnet run --project tools/Unitree.Net.TemplateCheck

The simulator and the wizard are WPF shells and therefore Windows-only. The engines behind them — Unitree.Net.Simulation and Unitree.Net.Wizard.Core — are plain net10.0 and run anywhere.

Transports

Three transports sit behind one interface, so the same application runs against hardware, a host-only link, or an in-process loopback with only a configuration change:

ManagedMulticast carries CDR payloads inside Unitree.Net's own framing — it is not RTPS and cannot reach robot firmware. See native/README.md to build the native shim.

Safety

These robots weigh tens of kilograms and move in a real space. Built into the SDK:

• A safety envelope bounds velocity, torque, gains and per-tick setpoint slew.
• The velocity stream keeps commands flowing; if the process dies the robot stops within half a second, and an explicit commandTimeout covers a remote source that vanishes.
• Fall detection and motor temperature limits latch an emergency stop.
• LLM motion functions are off by default and require two separate opt-ins to enable.

Read docs/safety.md before running low-level control.

Building

dotnet build Unitree.Net.slnx
dotnet test  Unitree.Net.slnx

Requires the .NET 10 SDK. The native shim is optional and built separately with CMake.

Documentation

Full documentation lives in docs/:

• Getting started
• Architecture
• DDS networking — read this when nothing connects
• Low-level control
• Safety
• Navigation
• AI workflows
• ROS 2 bridge
• Simulator
• Robot Wizard
• VS Code extension

Project planning is in PLAN.md; current status in PROGRESS.md.

PROGRESS.md deliberately separates "builds and passes tests" from "validated on hardware". Nothing in this repository has been run against a real robot.
