3. Scope of Application

This policy applies to all users and deployers of Walker Tienkung Robots, regardless of where the robots are used.

4. User Obligations and Responsibilities

(1) Research Use and Commercialization Restrictions

1. Users undertake that the initial purpose of the robots is research only, including academic research, technology development experiments, and research project testing. Unless secondary development is performed in compliance with applicable legal and regulatory requirements for the target scenario, robots must not be directly used in any commercial activities, such as product promotion, commercial service delivery, or industrial production.
2. If users wish to use robots for commercial purposes, they must do so on the basis of compliant secondary development. Such development must comply with this AUP and all relevant laws and regulations, and users should proactively file the secondary development plan with the Company before starting.
3. For multi‑party research collaborations, users must ensure that the overall project scope complies with this AUP and must supervise partners’ use of the robots.

(2) Safety Obligations

1. Before using the robots, users shall carefully read and understand the User Manual, operation guides, and safety notices, and become familiar with the robot’s functions and potential risks. Users must follow the correct procedures for starting, operating, and shutting down the robots to avoid incidents such as physical collisions, personal injury, or property damage. For example, when starting the robot, ensure it stands on a stable surface with no nearby obstacles; do not arbitrarily modify motion parameters unless guided by qualified personnel.
2. To prevent harm to nearby people and the environment, users shall operate the robots only in suitable venues with adequate space, free from obstacles and hazards. Appropriate warning signs should be placed to remind bystanders to keep a safe distance. Indoor environments should be spacious enough to avoid collisions with obstacles; outdoor environments should feature flat, solid ground away from water, roads, and crowded areas.
3. Users shall regularly inspect and maintain the robots, including but not limited to checking battery status, mechanical wear, and software updates, to ensure that the robots remain in good working condition. If any fault or safety risk is found, the user shall immediately stop using the robot and contact the Company’s support team. Users must not attempt repairs on their own. Software updates should be applied in a timely manner to obtain the latest features and security patches.

(3) Data Use and Protection

1. Regardless of whether the Company collects them, data generated during the use of the robots (excluding proprietary data) are held by the Company. Without the Company’s written authorization, users may use such data only within the scope allowed by this AUP and must not disclose, sell, or share them with third parties.
2. Unless otherwise agreed, proprietary data collected by users for their own research belong to the users. However, users must ensure that the collection and use of proprietary data comply with applicable laws, regulations, and data‑security requirements.
3. For data involving personal privacy, deployers shall strictly comply with privacy protection laws and regulations and adopt encryption, access control, and other necessary measures to prevent data leakage. For example, biometric data (such as voiceprints, facial images, gait data, etc.) should be stored in encrypted form with strict access controls so only authorized personnel can access them.

(4) Responsibilities for Secondary Development

1. If users perform secondary development, they must ensure compliance with local laws, regulations, and this AUP. They must not maliciously modify safety mechanisms or functional limits, nor develop features intended for illegal purposes, such as infringing privacy or conducting malicious attacks.
2. Users shall file a secondary development plan with the Company before starting, providing necessary information such as the development purpose, expected outcomes, and data usage plans. Filing materials should include, but are not limited to: team member information, tools and technologies used, development schedule, data sources, and data usage scope. The Company reserves the right to restrict or stop unfiled secondary development activities, including limiting robot usage and requiring users to stop development and restore the robot to its original state.
3. For robots used commercially after secondary development, users are solely responsible for completing all required compliance approvals and certifications to meet commercial standards. All risks and liabilities resulting from secondary development and commercial use shall be borne by the users. The Company assumes no responsibility for faults, safety incidents, or legal violations arising from such activities, and users shall compensate the Company for any resulting losses, including reputational damage and legal costs.

5. Deployer Monitoring and Deployment Responsibilities

(1) Deployment Compliance

1. Deployers shall ensure that deployment scenarios comply with research and teaching use requirements or meet the conditions for commercial use after secondary development. Robots must not be deployed in prohibited commercial venues or used for military or terrorist activities. Before deployment, deployers shall thoroughly assess the environment to ensure safety, stability, and compliance with all relevant laws, regulations, and safety standards.
2. If multiple users operate the robots in the same deployment scenario, deployers shall establish usage rules and management procedures to ensure that all users are aware of and comply with this AUP and related rules. Deployers shall supervise user behavior and promptly correct any violations.

(2) Safety Monitoring

1. Deployers shall establish effective safety monitoring mechanisms to track robot status in real time, including (but not limited to) position, motion trajectory, and operation behavior. Technical means should be used to detect abnormal situations, such as the robot leaving its designated area or exhibiting abnormal speeds or movements.
2. Safety monitoring data shall be analyzed periodically to evaluate usage risks, identify potential hazards, and implement preventive and corrective measures. If misuse or abuse is suspected, deployers shall immediately halt robot operation, notify the user and the Company, and cooperate with investigations.

(3) Compliance with the EU AI Act

1. If deployment occurs within the EU or involves EU‑related business, deployers shall ensure that robots and related deployment activities comply with the requirements of the EU Artificial Intelligence Act. Deployers shall assess the risk level of the AI system; if the robot is classified as a “high‑risk AI system”, they must fulfill all obligations stipulated by the Act.

6. Handling of Violations

1. If the Company discovers that a user or deployer has violated this AUP, it may take the following measures:
   1. Issue a written warning requiring immediate cessation of the violation.
   2. Suspend or terminate the violator’s right to use the robots.
   3. Require the violator to compensate the Company for all losses caused by the violation, including (but not limited to) product recall costs, legal compensation, and reputation recovery expenses.
   4. If the violator is a developer, the Company may revoke their developer registration and prohibit further development activities using Company robots.
2. If a violation is suspected to be illegal, the Company will report it to relevant authorities and cooperate with law‑enforcement investigations. The violator shall bear all corresponding legal liabilities.

7. Disclaimer

1. The Company is responsible for product quality only when robots are used in accordance with this AUP and the User Manual. For any faults, damage, safety incidents, or losses caused by misuse, abuse, unfiled secondary development, or other violations, the Company assumes no responsibility.
2. While the Company strives to provide safe and reliable products, due to technical limitations and the complexity of real‑world environments, unexpected events may still occur. For incidents resulting from unforeseeable or unavoidable causes, the Company will assist users and deployers in handling the situation but will not assume full liability.
