  1. Operator
    The panel shows error E-217 and the tractor is losing power.
  2. Assistant

    E-217 means low pressure in the fuel circuit. Try this, in order:

    1. 1.Check the primary fuel filter and drain water from the separator.
    2. 2.Make sure there is no air in the priming pump (left side valve).
    3. 3.If the code stays on after starting, don’t push the engine.

  3. Operator
    I already changed the filter and it’s the same.
  4. Assistant

    Then it may be the high-pressure pump. This needs a technician.

    A ticket will be opened with this conversation’s history.

A leading agricultural machinery distributor partnered with AlamedaDev to develop an AI-powered conversational chatbot capable of resolving complex technical issues by interpreting fault indicators, error codes, and technical documentation. The system was designed to provide real-time support to both operators and distributors, increasing user autonomy and reducing the workload on technical support teams.

The Problem

  • Faster technical support response

    When a machine is down, operators need an immediate solution to minimize downtime. Traditional support does not always meet this urgency, especially during peak agricultural seasons.

  • Limited access to technical knowledge

    Not all users have full manuals or experience to accurately interpret machinery failures.

  • Complex error codes

    Error codes in agricultural machinery are complex and not easily accessible to operators, slowing down diagnosis.

  • High dependency on specialized technicians

    Support for common issues relies heavily on qualified technicians, creating bottlenecks and additional costs.

Phase 1: Integration and structuring of technical documentation

  • Integration of technical manuals

    Official manufacturer documentation: user manuals, service manuals, and technical schematics.

  • Technician knowledge base

    Real cases and resolved tickets from technicians, structured to enrich the AI model.

  • Error code catalog

    Updated catalog of error codes and possible technical solutions.

  • Multilingual support

    Multilingual support for operators and distributors in different markets.

Phase 2: Development of NLU models and agent orchestration

  • Natural Language Understanding (NLU)

    NLU models fine-tuned to understand technical language, symptoms, and terminology specific to the agricultural sector.

  • Speech-to-Text and Text-to-Speech

    Voice-to-text and text-to-voice conversion optimized for field use, even in noisy environments.

  • Technical response generation

    LLM + RAG with agent orchestration to generate responses based on manuals and technical expertise.

  • Business customization

    Adapting the models to each brand, machinery line, and technical context.

Phase 3: Model training with real examples

Users describe the issue via text or voice (e.g., 'tractor shows error code E212 at startup').

The system transcribes voice inputs and extracts intent, context, error codes, and symptoms.

Responses are generated using LLM + RAG with agent orchestration, combining official manuals and expert knowledge.

The system delivers guided solutions or diagnostics in text or voice, adapted to the user's environment (field, workshop, office).

Phase 4: Field optimization for voice + text interaction

Transfer learning techniques and real-world conversation samples were used to optimize understanding of technical language in diverse environments.

  • Integration of ticket histories

    Ingestion of past support tickets with incident descriptions and applied solutions.

  • Email analysis

    Processing of emails received by technical support to extract common issue descriptions.

  • Use of images and videos

    Integration of images and videos sent by customers to enhance understanding of incident context.

  • Recorded support calls

    Where available, processing of recorded calls to extract linguistic patterns and technical vocabulary.

  • Transfer learning and continuous adaptation

    Use of pretrained models progressively fine-tuned with sector- and company-specific data.

What we delivered

1. An assistant that identifies machine error codes and explains the likely cause and the fix.

2. Answers grounded in the manufacturer’s technical manuals, including scanned documents read through OCR.

3. Real-time answers for operators and dealers working in the field.

Future Enhancements

  • Emotion recognition

    Detecting tone in user queries to adapt responses in critical situations.

  • Proactive support

    Integration with telemetry systems to anticipate failures and recommend preventive actions.

  • CRM integration

    Logging incidents and queries into CRM for better customer traceability.

The Potential of AI-Powered Technical Chatbots in the Industrial Sector

NLU models extract intent, context, error codes, and symptoms, ensuring accurate comprehension.

Responses are generated using LLM + RAG, orchestrated by agents, drawing on official documentation and technical expertise.

The multimodal pipeline enables accurate and natural interactions via text or voice, tailored to the user's environment (field, workshop, office).

Applications Across Multiple Support Scenarios
