Core Viewpoint - The trend towards robot lightweighting is becoming a consensus in the industry, driven by the need for improved performance such as endurance and response speed, as exemplified by Tesla's Optimus Gen2 robot which has reduced weight and increased speed compared to its predecessor [1] Group 1: Lightweighting Materials - Magnesium alloy is identified as an ideal lightweight material for robots, with a density of 1.74g/cm3, which is about two-thirds that of aluminum and less than a quarter of steel, providing significant lightweighting advantages [2] - A new magnesium alloy robot launched by Estun at the 2024 World Intelligent Manufacturing Conference demonstrated a weight reduction of approximately 33% for similar components compared to aluminum alloy, and an overall weight reduction of 11% [2] - Lijin Technology has signed a strategic cooperation agreement with four companies specializing in magnesium alloys and humanoid robot development to initiate a joint research project focused on magnesium alloy humanoid robots [2][3] Group 2: Technological Advantages - Magnesium alloy offers three main advantages for lightweighting in robots: superior weight reduction compared to aluminum, cost advantages due to low raw material prices, and the applicability of semi-solid processes to address corrosion resistance [3] - A joint research center will be established to focus on key technologies such as magnesium alloy shell forming, process optimization, and lightweight structural design [3] Group 3: Industry Growth Potential - Elon Musk has expressed confidence in the humanoid robot industry's growth potential, predicting that Tesla's Optimus robot will achieve mass production at a low cost, with a target output of millions of units priced potentially under $20,000 [5] - According to optimistic forecasts, global humanoid robot sales could reach 900,000 units by 2029 and exceed 1.5 million units by 2030, with projections of 8 million units by 2035 as the industry matures [6] - Dongwu Securities noted that the adoption rate of magnesium alloys in humanoid robots is expected to outpace that in the automotive sector due to various factors, including lower corrosion resistance requirements in ToB scenarios and the smaller size and weight of robot components [7]
