Optimus (Tesla) vs ELIXIS W (Addverb)

Optimus features a bipedal design with dimensions of 173cm x 55cm x 38cm and 57 kg weight, optimized for human-like mobility in varied terrains. ELIXIS W employs a wheeled humanoid architecture at 175cm x 60cm x 50cm and 75 kg, emphasizing industrial stability and integration into warehouse infrastructure without structural changes. The wheeled base of ELIXIS W enhances energy efficiency for repetitive tasks, while Optimus prioritizes general-purpose versatility. Optimus carries 20 kg and can deadlift 68 kg. ELIXIS W has 41 degrees of freedom, carries 10 kg and can deadlift 15 kg.

Optimus achieves a maximum speed of 8 km/h using Tesla FSD-based vision, stereo cameras, and internal proprioception for navigation. ELIXIS W reaches 5.4 km/h with Visual SLAM, LiDAR mapping, and Indoor SLAM, suited for precise movement in structured environments. Optimus offers higher speed for broader applications, whereas ELIXIS W's wheeled system improves uptime in warehouses. Optimus reaches 2.2 m/s. ELIXIS W reaches 1.5 m/s. Optimus's mobility type is bipedal. Optimus navigates with Tesla FSD-based vision system, stereo cameras and internal proprioception. Optimus stands 173 cm tall and weighs 57 kg. ELIXIS W stands 175 cm tall and weighs 75 kg.

Optimus perceives the world mainly through cameras, backed by an IMU, tactile sensing in its fingers and force and torque sensing in its feet and joints. ELIXIS W uses 4x stereo depth cameras, 1x 3D LiDAR, 2x 9-axis IMU, dual-encoders per joint, and optional tactile finger sensors. Both employ multi-modal sensing, but ELIXIS W emphasizes SLAM for indoor mapping, while Optimus focuses on FSD vision integration. Optimus's sensors include vision cameras and tactile sensing on the fingers. Optimus runs for about 8 hours per charge and recharges in 1–2 hours.

Optimus runs on Tesla's custom OS with AI and FSD integration, enabling fully autonomous control with remote supervision options. ELIXIS W supports autonomous operation, teleoperation, and learned behaviors via ROS2 and proprietary stack with Python APIs. Optimus leverages vehicle-derived AI for real-time planning, contrasting ELIXIS W's focus on ROS2 for industrial adaptability. Optimus is listed as semi-autonomous to fully autonomous. Optimus's control method is listed as fully autonomous with optional remote supervision. ELIXIS W's control method is listed as autonomous, teleoperation, learned behaviors. Optimus runs Tesla custom OS with AI and FSD integration.

Optimus provides approximately 8 hours of operational use from its battery. Wheeled design in ELIXIS W contributes to higher energy efficiency compared to Optimus's bipedal power demands. ELIXIS W runs for 1.5–2 hours per charge and recharges in 2 hours. Optimus's safety features include emergency stop, obstacle detection and compliant actuators. ELIXIS W's safety features include force limiting, collision detection, emergency stop and collaborative mode. ELIXIS W's sensors include 4x Stereo Depth Cameras, 1x 3D LiDAR, 2x 9-axis IMU and tactile Finger Sensors. ELIXIS W's listed uses include industrial inspection, warehouse material handling and package sorting.

Optimus targets manufacturing, research, logistics, infrastructure inspection and remote operations, with the versatility of a biped. ELIXIS W, a wheeled robot, is built for intralogistics, warehouse material handling, package sorting, industrial inspection and collaborative assembly on factory floors. Its wheeled base suits flat, high-frequency warehouse tasks, while Optimus's legs address broader, less structured spaces. ELIXIS W is listed as fully autonomous at Level 4 indoors, carries 10 kg and can lift 15 kg momentarily.

Optimus is listed at $20,000 to $50,000 and is not yet on sale. ELIXIS W is listed at $11,000 to $16,000, and Addverb sells the wheeled variant through a contact form, with no price shown. Its lower price gives better value for structured warehouse deployments, while Optimus's price reflects bipedal reach and a 2.3 kWh pack that runs about 8 hours, against ELIXIS W's 1.5 to 2 hours.

Optimus has an emergency stop, obstacle detection and compliant actuators. ELIXIS W has force limiting, collision detection, an emergency stop, a collaborative mode and two-layer safety, with six STM32 safety controllers running alongside its Jetson Orin and Intel i7 computers. ELIXIS W is rated for indoor use from 0 to 50 °C. Its collaborative emphasis and dedicated safety controllers support human-robot work in factories, while Optimus's compliant actuators give way on contact.
