Group 1 - The article emphasizes the necessity of integrating liquid cooling solutions in humanoid robots due to the presence of numerous heat-generating components within their chests, highlighting a company with automotive thermal management technology as having a significant technical advantage [1] - It points out that there is still room for improvement in the safety of humanoid robots, with the potential for the addition of electronic skin that mimics human touch, identifying a listed company as one of the leading firms in the electronic skin sector [1] - The core bottleneck for mass production of humanoid robots is identified as the dexterous hand, with tendon-driven mechanisms being one of the two major technological trends, and two companies are noted to have a first-mover advantage in this area, likely benefiting from the upcoming production wave [1]

Core Viewpoint - The incident involving the humanoid robot DeREK, which exhibited erratic behavior during a competition, raises significant concerns regarding the safety and reliability of robotic systems, particularly in emergency situations [1][34]. Technical Explanation - The robot's malfunction was attributed to the activation of a full-body strategy while being suspended, leading to a failure in recognizing the ground beneath it, resulting in loss of control [7][8]. - The remote emergency stop system, although present, was ineffective, taking 5 seconds to activate, which is deemed excessively long for emergency situations [13][15]. - The design documentation indicated that the robot should not operate in a suspended state, yet the system reverted to a walking mode, causing the malfunction [11][12]. Safety Concerns - The battery's location and design pose risks during emergencies, as accessing it requires proximity to the robot, which can be dangerous when the robot is out of control [18]. - The robot's motors are powerful, making it difficult for individuals to intervene physically without risking severe injury [21]. - The emergency stop system relies on wireless communication, which is not suitable for safety-critical applications due to potential signal interference [24][25]. Recommendations for Improvement - A multi-step safety solution is suggested, including adherence to safety standards such as PL(d) or ASIL-D for actuator and battery management systems [36]. - Continuous testing, failure mode analysis, and single-point failure protection should be integral to the development process of robotic systems [36]. - The implementation of a more reliable emergency stop mechanism that does not depend on wireless communication is recommended to enhance safety [36].
