## 🖥️ Frontend Architecture (Next.js 16)
### Next.js 16 Features Implementation
#### 1. **App Router with Server Components**
```typescript
// app/dashboard/page.tsx (Server Component)
export default async function DashboardPage() {
// Server-side data fetching with ISR
const robotData = await fetchRobotsFromROS({
next: { revalidate: 30 } // ISR with 30s revalidation
})
return (
<Dashboard robots={robotData} />
)
}
// app/api/robots/route.ts (Route Handlers)
export async function GET(request: Request) {
const robots = await getActiveRobots()
return NextResponse.json(robots)
}
export async function POST(request: Request) {
const robot = await createRobot(await request.json())
return NextResponse.json(robot, { status: 201 })
}
```
#### 2. **React 19 Concurrent Features**
```typescript
'use client'
import { Suspense, useTransition } from 'react'
import { ErrorBoundary } from 'react-error-boundary'
export function RobotControlPanel() {
const [isPending, startTransition] = useTransition()
const handleEmergencyStop = () => {
startTransition(async () => {
await emergencyStopAllRobots()
})
}
return (
<ErrorBoundary fallback={<ErrorFallback />}>
<Suspense fallback={<LoadingSkeleton />}>
<RobotControls
onEmergencyStop={handleEmergencyStop}
disabled={isPending}
/>
</Suspense>
</ErrorBoundary>
)
}
```
#### 3. **Advanced TypeScript 5.6 Features**
```typescript
// Advanced type utilities for robotics
type RobotState<T extends RobotType> = {
[K in keyof T]: T[K] extends Sensor
? SensorReading<T[K]>
: T[K] extends Actuator
? ActuatorCommand<T[K]>
: never
}
// Generic robot control interface
interface RobotController<T extends RobotCapabilities> {
connect(): Promise<Connection<T>>
execute<K extends keyof T>(
command: K,
params: T[K]['params']
): AsyncGenerator<T[K]['result'], void, unknown>
disconnect(): Promise<void>
}
// Type-safe ROS 2 message handling
type ROS2Message<T> = {
header: {
stamp: { sec: number; nanosec: number }
frame_id: string
}
data: T
} & (T extends Array<infer U> ? { length: number } : {})
// Real-world usage
const scoutController: RobotController<ScoutCapabilities> = new ScoutController()
// Type-safe command execution
for await (const result of scoutController.execute('move', {
linear: { x: 0.5, y: 0, z: 0 },
angular: { x: 0, y: 0, z: 0.1 }
})) {
console.log('Movement result:', result)
}
```
#### 4. **Tailwind CSS 4.0 with CSS-in-JS Hybrid**
```typescript
// styles/globals.css
@layer components {
.robot-card {
@apply bg-gradient-to-br from-slate-900 to-slate-800;
@apply border border-slate-700 rounded-xl;
@apply shadow-2xl shadow-slate-900/50;
@apply backdrop-blur-sm;
}
.sensor-indicator {
@apply relative;
&::before {
content: '';
@apply absolute inset-0 rounded-full;
@apply bg-gradient-to-r from-emerald-400 to-cyan-400;
@apply opacity-20 animate-pulse;
}
}
}
// Component with styled-jsx integration
export function RobotStatusCard({ robot }: { robot: Robot }) {
return (
<div className="robot-card">
<style jsx>{`
.status-indicator {
background: ${robot.online ? '#10b981' : '#ef4444'};
animation: ${robot.online ? 'pulse 2s infinite' : 'none'};
}
`}</style>
<div className="status-indicator" />
<h3>{robot.name}</h3>
</div>
)
}
```

## 🔄 Real-time Communication (WebRTC 1.0)
### WebRTC 1.0 Implementation
#### 1. **QUIC Transport Protocol**
```typescript
// WebRTC configuration with QUIC transport
const rtcConfiguration: RTCConfiguration = {
iceServers: [
{ urls: 'stun:stun.cloudflare.com:3478' },
{
urls: 'turn:turn.cloudflare.com:3478',
username: 'robotics-user',
credential: 'secure-token'
}
],
iceTransportPolicy: 'all',
bundlePolicy: 'max-bundle',
rtcpMuxPolicy: 'require',
// QUIC transport (WebRTC 1.0)
sdpSemantics: 'unified-plan',
peerIdentity: 'robotics-webapp'
}
// Connection establishment
class RoboticsPeerConnection extends RTCPeerConnection {
private dataChannels: Map<string, RTCDataChannel> = new Map()
async connectToRobot(robotId: string) {
const offer = await this.createOffer({
offerToReceiveAudio: false,
offerToReceiveVideo: true
})
await this.setLocalDescription(offer)
// Send offer to robot via signaling server
const answer = await this.signalingServer.sendOffer(robotId, offer)

})
this.createDataChannel('sensor-stream', {
ordered: false, // Allow packet reordering for performance
maxRetransmits: 0 // No retransmits for real-time data
})
}
}
```
#### 2. **Real-time Robotics Control**
```typescript
// OSC over WebRTC implementation
class OSCWebRTCBridge {
private oscClient: OSC.Client
private rtcConnection: RTCPeerConnection
private controlChannel: RTCDataChannel
constructor(robotIP: string, robotPort: number = 9000) {
this.oscClient = new OSC.Client(robotIP, robotPort)
this.rtcConnection = new RoboticsPeerConnection()
this.setupDataChannel()
}
private setupDataChannel() {
this.controlChannel = this.rtcConnection.createDataChannel('osc-control', {
protocol: 'osc',
negotiated: true,
id: 0
})
this.controlChannel.onmessage = (event) => {
const oscMessage = OSC.Message.fromBuffer(event.data)
this.handleOSCMessage(oscMessage)
}
}
async sendRobotCommand(command: RobotCommand) {
const oscMessage = new OSC.Message('/robot/control')
oscMessage.add(command.type)
oscMessage.add(command.value)
if (this.controlChannel.readyState === 'open') {
this.controlChannel.send(oscMessage.toBuffer())
} else {
// Fallback to direct OSC
await this.oscClient.send(oscMessage)
}
}
private handleOSCMessage(message: OSC.Message) {
switch (message.address) {
case '/robot/status':
this.updateRobotStatus(message.args)
break
case '/sensor/imu':
this.processIMUData(message.args)
break
case '/camera/frame':
this.displayCameraFeed(message.args[0])
break
}
}
}
```
#### 3. **WebRTC Data Channels for Sensor Streaming**
```typescript
interface SensorStreamConfig {
sensorId: string
dataType: 'imu' | 'lidar' | 'camera' | 'audio'
sampleRate: number
compression: 'none' | 'gzip' | 'lz4'
priority: 'low' | 'normal' | 'high'
}
class SensorDataStreamer {
private streams: Map<string, RTCDataChannel> = new Map()
private compressionWorkers: Map<string, Worker> = new Map()
async createSensorStream(config: SensorStreamConfig): Promise<RTCDataChannel> {
const channel = this.peerConnection.createDataChannel(
`sensor-${config.sensorId}`,
{
ordered: config.dataType === 'imu', // IMU needs ordering
maxPacketLifeTime: config.priority === 'high' ? 100 : 1000,
maxRetransmits: config.priority === 'high' ? 3 : 0
}
)
// Set up compression if needed
if (config.compression !== 'none') {
const worker = new Worker('/workers/compression-worker.js')
worker.postMessage({ type: 'init', algorithm: config.compression })
this.compressionWorkers.set(config.sensorId, worker)
channel.onmessage = (event) => {
worker.postMessage({ type: 'decompress', data: event.data })
}
worker.onmessage = (event) => {
this.handleSensorData(config.sensorId, event.data)
}
} else {
channel.onmessage = (event) => {
this.handleSensorData(config.sensorId, event.data)
}
}
this.streams.set(config.sensorId, channel)
return channel
}
private handleSensorData(sensorId: string, data: ArrayBuffer) {
// Process sensor data based on type
const sensorConfig = this.getSensorConfig(sensorId)
switch (sensorConfig.dataType) {
case 'imu':
this.processIMUData(new Float32Array(data))
break
case 'lidar':
this.processLidarData(new Uint16Array(data))
break
case 'camera':
this.displayCameraFrame(data)
break
