Summary of Key Points from the Conference Call Industry Overview - The conference call discusses the robotics motion capture industry, focusing on data collection methods and challenges faced by companies in this sector [1][2][4]. Core Insights and Arguments - **Data Collection Modes**: There are four primary modes of data collection in motion capture systems: 1. Real human motion capture with a physical robot, yielding 30% to 50% effective data but at a high cost. 2. Combination of real motion capture and virtual engines, allowing for 15 to 20 minutes of data collection per day at a lower cost. 3. Pure motion capture systems without physical robots, resulting in a lower effective data ratio. 4. Use of synthetic data for large-scale training, which is currently debated [2][19]. - **Data Validity Measurement**: Validity is assessed through initial human motion verification followed by robot posture validation. There is no industry standard, and the process involves multi-sensor information fusion to ensure reliability [5]. - **Data Collection Efficiency**: The efficiency of data collection is low, with 1,300 seconds of data requiring experienced motion capture experts to work continuously for several days. The main issues are the immaturity of virtual body software and challenges in interacting with real objects [6][3]. - **Cost of Data Collection**: The cost of effective data collection is approximately 300 yuan per second, with repeated data costing around 60 yuan per second. Future projections suggest costs may drop to around 200 yuan in 1-3 years, potentially below 100 yuan with student involvement [3][22]. - **Mapping Challenges**: The primary challenge in motion capture technology is the mapping of human actions to robotic actions. Current solutions often prioritize accuracy over posture, which can lead to discrepancies in execution [7][9]. - **Role of Data Factories**: Establishing data factories can significantly enhance data collection efficiency, allowing for the use of hundreds to thousands of devices to gather extensive data, which is crucial for training algorithms [10]. - **Customer Demand**: The most significant current demand comes from companies like Shiyuan, which has placed a large order of 1,000 sets, while most other companies remain in the verification stage [16]. Other Important but Overlooked Content - **Application Prioritization**: Data collection priorities are determined by customer needs and application scenarios rather than specific actions [11][12]. - **Domestic Companies' Focus**: Major domestic companies are concentrating on data collection in areas such as home services, healthcare, and rescue applications, tailoring their data collection environments accordingly [13]. - **Integration of Data Types**: The integration of motion capture data with force and tactile information is being explored to enhance the capabilities of motion capture devices [18]. - **Challenges in Mapping Solutions**: Companies face challenges in understanding human biomechanics when designing mapping solutions, often outsourcing this work to specialized motion capture firms [25]. - **Future Cost Reduction Strategies**: Cost reduction in data collection can be achieved through bulk production and collaboration with educational institutions to utilize student labor [21].
