Dora

Dora, developed by Noetix Robotics, a Beijing-based startup founded in September 2023, represents a compact, product-level humanoid robot optimized for embodied intelligence applications. Launched in May 2024, Dora stands approximately 100-120 cm tall and weighs 20-25 kg, featuring a lightweight aluminum alloy structure with plastic shell options in variants like EVA, Deep Space Black, and Bumblebee. Its architecture centers on 20-26 degrees of freedom (DOF), with 6 DOF per leg, 4-7 DOF per arm (optional dexterous hands with 11 DOF), enabling agile bipedal locomotion including straight-leg walking, anthropomorphic running, stair climbing, and multi-terrain navigation over grass, snow, slopes, and obstacles. Powered by an NVIDIA Jetson Orin edge-AI module (8GB GPU, 40 TOPS, 6-core Arm Cortex-A78AE CPU with Ampere GPU featuring 1024 cores and 32 Tensor Cores), Dora processes 3 structured-light depth cameras (two downward-slanting, one forward) for millimeter-precise 3D vision, supporting autonomous obstacle avoidance, visual recognition, and navigation. Motion control leverages deep reinforcement learning (RL) and imitation learning algorithms, developed in-house, allowing dynamic balance, payload handling up to 5-10 kg, peak joint torques of 120-150 N·m, and speeds up to 1.5 m/s (3.6 km/h). A 7-inch front display, 6-mic array, single speaker, and LLM integration enable low-latency speech-visual interaction, voice commands, and multimodal dialogue. The all-electric drive system uses force-controlled joints for safe human coexistence, with a 48V/10Ah quick-release battery providing 2-4 hours runtime. Interfaces include 4 USB, 2 Ethernet, and 1 HDMI ports, facilitating secondary development on a presumed Jetson SDK with open-source elements. Noetix's background in competition robots like N1 informs Dora's design, with early milestones including multi-terrain tests by late 2023 and grasping teleoperation by June 2024. While primarily prototyped for R&D, Dora targets commercialization in education, elder care, home assistance, reception, and family services, with company financing exceeding 100 million yuan supporting scaling. Real-world deployments remain limited to internal tests and exhibitions (e.g., Beijing displays), but its sub-$10,000 pricing positions it for ToB/ToC markets amid China's humanoid boom. Future integrations promise expanded LLM capabilities and dexterous manipulation, bridging research to practical utility.
