I. Performance Matching Challenges
1. Trade-off between lightweight and rigidity: metals are heavy, while standard plastics lack strength.
2. Poor fatigue and creep resistance cause deformation, cracking and precision loss under frequent motion.
3. Insufficient wear resistance and self-lubrication lead to abrasion, jamming and abnormal noise.
4. Low impact tolerance results in fragile structures and low collision fault tolerance.
II. Cost and Mass Production Challenges
1. High-end materials raise overall robot and joint costs.
2. Missing mid-range material systems, leaving no cost-effective mass-production options.
3. Premium materials face supply shortages and low molding yields for complex structures.
III. Environmental Adaptability Challenges
1. Poor thermal stability causes deformation and precision degradation under temperature changes.
2. Weak oil, dust and corrosion resistance accelerate material aging and delamination.
3. Inferior weatherability leads to yellowing and embrittlement in UV and humid environments.
IV. Human-Robot Interaction and Biomimicry Challenges
1. Rigid structures lack cushioning, increasing human-robot collision risks.
2. Flexible covers suffer from wear, shedding and yellowing with poor tactile and anti-fouling performance.
3. Immature soft-hard bonding causes delamination, failing commercial durability requirements.
V. Precision and Reliability Challenges
1. No specialized robotic material database leads to inaccurate simulation and high iteration costs.
2. Unstable batch consistency causes positioning deviation and low production yield.
3. Domestic high-end materials are limited, relying heavily on imports for precision components.
VI. Electrical Safety Challenges
1. Conventional materials lack flame retardancy and insulation for high-density electronics and battery systems.
2. Insufficient electromagnetic shielding causes signal interference and low positioning accuracy.
3. Traditional flame-retardant modification weakens mechanical performance, failing dual safety and structural demands.
VII. Pain Points in Process Standardization
1. Absence of robot-specific material standards; general materials cannot fit high-precision, high-frequency operation.
2. Thin-walled and complex-shaped parts suffer from molding defects such as warping and sink marks.
3. Poor repairability and recyclability increase replacement and maintenance costs.
Solution：
I. Mechanical performance dimension
- Mechanical Properties
- Low stiffness and easy deformation, not suitable for load-bearing metal substitution.
- Inferior fatigue and abrasion resistance, triggering cracks, creep, noise and dusting in long-term use.
- Weak anti-impact and low-temperature toughness, easy to break with low anti-risk ability.
II. Lightweight Structural Design
1. Metal parts add weight and cut battery life; common plastics are light yet not strong enough.
2. Hard to balance light weight and structural strength.
3. Thin-wall components warp easily, lowering assembly and movement precision.
III. Environmental Weatherability
1. Dimensions shift drastically amid temperature fluctuations.
2. Poor resistance to oil, dust and chemicals, susceptible to aging and surface peeling.
3. UV rays and humidity lead to yellowing, brittleness and performance decline.
IV. Safety and Electrical Properties
1. Subpar flame retardancy cannot satisfy safety criteria for batteries and control modules.
2. Flame retardant treatment weakens mechanical properties.
3. Unreliable insulation may cause electric leakage.
4. Absence of electromagnetic shielding disturbs sensors and positioning systems.
V. Human-Machine Interaction
1. Hard materials lack buffer protection against collisions.
2. Soft materials turn yellow, shed powder and wear out quickly.
3. Weak adhesion between hard and soft layers causes peeling and short service life.
VI. Mass Production Processes
1. Big batch discrepancies undermine product uniformity.
2. High-fiber materials flow poorly, raising reject rates for intricate molded pieces.
3. No dedicated robotic material grades; generic materials have poor adaptability.
VII. Cost and Commercial Viability
1. Premium materials are too expensive for large-scale manufacturing.
2. No cost-performance intermediate materials fill the product range gap.
3. Short service life and frequent breakdowns of standard plastics drive up after-sales expenses.
