L7 by Robot Era vs T800 by EngineAI

L7 measures 171 x 50 x 40 cm and weighs 65 kg, using alloy frame and polymer shells with 55 degrees of freedom and 12-DoF hands for dexterous manipulation. T800 is slightly taller at 173 cm and heavier at 75–85 kg, suited for heavy-duty tasks. L7's quasi-direct drive joints provide high torque up to 400 N·m and peak speeds of 25 rad/s, while T800 emphasizes robust build for industrial environments.

L7 achieves 14.4 km/h speed with SLAM-based navigation via multi-sensor fusion, including 3D LiDAR and stereo vision for agile movement. T800 reaches 2 m/s or more using visual SLAM and LiDAR mapping, prioritizing stability in heavy-duty scenarios. L7's higher speed supports dynamic tasks like tool handling, contrasting T800's focus on reliable locomotion in logistics.

L7 features stereo RGB-D cameras, LiDAR, IMU, gyroscope, force sensors, and ultrasonic sensors for real-time environmental sensing. T800 includes RGB cameras, stereo cameras, LiDAR, ultrasonic sensors, IMU, gyroscope, force sensors, and temperature sensors. Both enable obstacle avoidance, but L7's panoramic vision enhances 360° spatial perception.

L7 uses custom AI software with ERA-42 embodied AI computer, supporting Linux-based OS, ROS integration, and APIs for autonomous control. T800 employs proprietary OS with ROS2, Python, and C++ for learned behaviors and teleoperation. L7 integrates LLM for vision and language, while T800 focuses on collaborative human-robot interaction.

L7 uses typical lithium-ion batteries, supporting extended operations in factory settings. Both emphasize long-term power without specified runtime per charge, suitable for automation tasks.

L7 targets factory automation, sorting, tool handling, and research labs with agile dexterity for precise manipulation. T800 suits heavy-duty industrial tasks, robot boxing, retail assistance, human-robot interaction, and logistics. L7 excels in speed-demanding environments, while T800 handles broader interactive and robust applications.

L7's software includes custom AI with ERA-42, likely Linux OS and ROS integration, plus APIs for programming. T800 runs proprietary OS alongside ROS2, Python, and C++ for flexible development. Both support teleoperation and autonomous modes, enabling varied control interfaces.

L7 is priced at $120,000, offering high speed and dexterity for its cost. T800 ranges from about $25,000 for the base model to $80,000 for the top configuration, reflecting its larger build and heavy-duty focus. Value differs by application, with L7 providing agility at lower entry price.

L7 includes emergency stop, obstacle avoidance, real-time sensing, and torque-limited joints. T800 features force limiting, collision detection, emergency stop, and collaborative mode. Both prioritize safe operation in shared human environments.
