Tesla's Optimus is positioned as a versatile humanoid robot for industrial and domestic applications, leveraging Tesla's expertise in AI and autonomous driving. It features a compact design at 173cm tall and 57kg, with a maximum speed of 8 km/h and up to 8 hours of battery life for operational use. Key differentiators include its Tesla FSD-based vision system for navigation and fully autonomous control with remote supervision options, targeting manufacturing, logistics, and infrastructure tasks.
EngineAI's T800 targets heavy-duty industrial and interactive roles, offering a larger frame at 185cm and 85kg suited for demanding environments. Priced from $25,000 to $80,000, it reaches 10 km/h speeds and claims a 4-year battery lifespan, though likely referring to total capacity rather than continuous use. Distinctive aspects include visual SLAM navigation, support for teleoperation, and applications in robot boxing, retail assistance, and human-robot interaction.
Detailed Analysis

Design & Build Quality
Optimus measures 173cm x 55cm x 38cm and weighs 57kg, providing a lighter and more compact build compared to T800's 185 x 60 x 40 dimensions and 85kg weight. T800 supports heavier payloads up to 5kg per hand, while Optimus emphasizes compliant actuators for precise movements. Both feature multi-degree-of-freedom joints, but T800 includes advanced neck and waist articulation for human-like motion.

Mobility & Navigation
Optimus achieves a max speed of 8 km/h using Tesla FSD-based vision with stereo cameras and internal proprioception for navigation. T800 reaches 10 km/h and employs visual SLAM combined with LiDAR mapping for environmental awareness. Both enable autonomous movement, though T800 adds omni-directional perception for real-time obstacle avoidance.

Sensors & Perception
Optimus integrates RGB cameras, depth camera, LiDAR, IMU, force/torque sensors, gyroscope, accelerometer, and joint encoders. T800 includes RGB cameras, stereo cameras, LiDAR, ultrasonic sensors, IMU, gyroscope, force sensors, and temperature sensors. T800's setup supports 360-degree LiDAR for multi-dimensional awareness with millisecond-level processing.

AI Capabilities
Optimus runs on Tesla custom OS with AI and FSD integration for fully autonomous operation and real-time perception. T800 uses proprietary OS, ROS2, Python, and C++ with high-performance computing like AGX Orin for onboard AI decision-making. Both support learned behaviors, but Optimus emphasizes neural networks trained on Dojo for manipulation tasks.

Battery & Power Efficiency
Optimus provides approximately 8 hours of operational use from its battery. T800 is specified with a 4-year battery life, potentially indicating total lifespan or swappable design rather than continuous runtime. Optimus battery details suggest 2.3 kWh capacity with 100W idle consumption, while T800 power specs align with intensive industrial use.

Use-Case Suitability
Optimus suits manufacturing, research, logistics, infrastructure inspection, and remote operations with its lightweight design. T800 targets heavy-duty industrial tasks, robot boxing, retail assistance, human-robot interaction, and logistics automation. T800's robust build fits high-payload scenarios, while Optimus excels in precision autonomous tasks.

Pricing & Value
Optimus is priced at $20,000 - $50,000, offering a potentially lower entry cost for versatile applications. T800 ranges from $25,000 base to $80,000 high-end, reflecting scalability for advanced configurations. Price differences align with Optimus's focus on autonomy and T800's heavy-duty capabilities.

Safety Features
Optimus includes emergency stop, obstacle detection, and compliant actuators. T800 provides force limiting, collision detection, emergency stop, and collaborative mode. Both prioritize real-time detection, with T800 adding force sensors for safer human interaction.
