Replay: Generate UI from Robotics Control Software Tutorials.

TL;DR: Replay enables developers to rapidly prototype and generate UI code directly from video tutorials of robotics control software, bridging the gap between learning and implementation.

Robotics control software is powerful, but mastering its UI can be a steep learning curve. Countless hours are spent watching tutorials, pausing, rewinding, and painstakingly replicating the demonstrated interfaces. What if you could simply record a tutorial and have the UI code automatically generated?

That's the power of Replay.

Replay is a video-to-code engine that uses Gemini to reconstruct working UI from screen recordings. Unlike traditional screenshot-to-code tools, Replay understands the intent behind the user's actions in the video, allowing for more accurate and functional code generation. This is especially critical in the complex world of robotics control software, where understanding the sequence of operations is just as important as the visual layout.

The Challenge: From Tutorial to Tangible UI#

Robotics engineers often rely on video tutorials to learn how to use specific control software. These tutorials showcase intricate workflows, parameter adjustments, and real-time data visualization. However, translating the visual information into functional code is a time-consuming and error-prone process.

Consider the following scenario: An engineer needs to implement a specific motion planning algorithm within their robotics control software. They find a tutorial that perfectly demonstrates the process. The tutorial shows the UI elements, the sequence of operations, and the expected output.

The traditional approach involves:

1. •Watching the tutorial multiple times.
2. •Manually identifying and recreating UI elements (buttons, sliders, graphs).
3. •Implementing the logic to connect the UI elements to the underlying control algorithms.
4. •Debugging and refining the UI to match the tutorial's behavior.

This process can take days, even weeks, depending on the complexity of the UI and the engineer's familiarity with the software.

Replay offers a radically different approach. By simply recording the tutorial, Replay can automatically generate the UI code, significantly reducing development time and effort.

Replay: Behavior-Driven UI Reconstruction#

Replay utilizes "Behavior-Driven Reconstruction," which treats the video as the source of truth. This means Replay doesn't just look at static images; it analyzes the sequence of actions performed in the video to understand the underlying logic and generate corresponding code.

Here's a comparison of Replay with other UI generation tools:

Replay excels in understanding the dynamic aspects of UI interactions, making it particularly well-suited for robotics control software.

Generating UI from a Robotics Tutorial: A Step-by-Step Guide#

Let's walk through the process of using Replay to generate UI code from a robotics control software tutorial.

Step 1: Record the Tutorial#

Use your preferred screen recording software to capture the tutorial. Ensure the video is clear and captures all relevant UI elements and interactions.

💡 Pro Tip: Record in high resolution and minimize distractions on your screen for optimal results.

Step 2: Upload to Replay#

Upload the recorded video to the Replay platform. Replay supports various video formats and resolutions.

Step 3: Replay Analyzes the Video#

Replay's engine analyzes the video, identifying UI elements, user interactions, and the overall workflow. This process may take a few minutes, depending on the length and complexity of the video.

Step 4: Review and Refine the Generated Code#

Once the analysis is complete, Replay presents the generated code. You can review the code, make adjustments, and customize it to fit your specific needs.

typescript
// Example of generated code for a button click event
const handleStartButtonClick = async () => {
  console.log("Starting the motion planning algorithm...");
  // Code to initiate the motion planning process
  try {
    const response = await fetch('/api/startMotionPlanning', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ /* parameters from the UI */ }),
    });

    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }

    const data = await response.json();
    console.log("Motion planning started successfully:", data);
  } catch (error) {
    console.error("Error starting motion planning:", error);
    // Display error message to the user
  }
};

// Example of generated code for updating a graph
const updateGraph = (data: number[]) => {
  // Logic to update the graph with new data points
  console.log("Updating graph with data:", data);
  // Assuming you're using a charting library like Chart.js
  const chart = new Chart(document.getElementById('myChart') as HTMLCanvasElement, {
    type: 'line',
    data: {
      labels: Array.from({ length: data.length }, (_, i) => i.toString()),
      datasets: [{
        label: 'Real-time Data',
        data: data,
        borderColor: 'rgb(75, 192, 192)',
        tension: 0.1
      }]
    },
    options: {
      scales: {
        y: {
          beginAtZero: true
        }
      }
    }
  });
};

This example demonstrates how Replay can generate code for handling button clicks and updating graphs, two common tasks in robotics control software UIs.

Step 5: Integrate with Your Project#

Copy the generated code into your project and integrate it with your existing codebase. Replay supports various frameworks and libraries, making integration seamless.

📝 Note: Replay also offers Supabase integration, allowing you to easily connect your UI to a backend database for data storage and retrieval.

Case Study: Streamlining Robot Arm Control Interface Development#

A robotics startup was developing a new control interface for their robot arm. They had a series of video tutorials demonstrating the key features of the interface. Using Replay, they were able to generate the initial UI code in a matter of hours, saving them weeks of development time.

The generated code included:

• •Buttons for controlling the robot arm's movements.
