D7 by Pudu vs Walker Tienkung by UBTECH

D7 measures 170cm x 55cm x 38cm and weighs 50-80 kg, offering a slimmer profile than Walker Tienkung's 172 x 60 x 40 cm and 73 kg build. Both feature humanoid designs suited for human environments. Walker Tienkung maintains a fixed 73 kg weight, while D7 provides a variable range for potential configuration flexibility.

D7 achieves walking speeds of 1.5-3 m/s using visual SLAM, LiDAR mapping, and balance-assisted walking. Walker Tienkung reaches 7 km/h (about 1.94 m/s) with indoor SLAM, visual SLAM, and LiDAR mapping. D7 includes balance assistance for enhanced stability, while Walker Tienkung emphasizes indoor navigation precision.

D7 equips RGB cameras, depth camera, LiDAR, IMU, force/torque sensors, gyroscope, accelerometer, and joint encoders. Walker Tienkung adds stereo cameras, ultrasonic, and temperature sensors to RGB cameras, LiDAR, IMU, gyroscope, and force sensors. Walker Tienkung offers broader detection with ultrasonics and temperature monitoring.

D7 supports teleoperation, autonomous control, and learned behaviors on Linux-based OS with ROS 2 and Python SDK. Walker Tienkung uses autonomous control and learned behaviors with ROS2, proprietary software, Python, and C++. Both enable task adaptation through learned behaviors, differing in control flexibility.

Both D7 and Walker Tienkung provide 3-5 years battery life, supporting extended operations. No specific charging times or capacity details differ between them. This longevity suits prolonged use cases like research and logistics.

D7 applies to manufacturing, research, logistics, infrastructure inspection, and remote operations. Walker Tienkung serves scientific research, scenario innovation, logistics, rescue missions, and industrial automation. Overlapping logistics use contrasts with D7's remote operations and Walker Tienkung's rescue focus.

D7 runs Linux-based OS with ROS 2 support and Python SDK for development. Walker Tienkung supports ROS2, proprietary software, Python, and C++. Both leverage ROS2 for compatibility, with Walker Tienkung adding C++ for performance-critical tasks.

D7 prices at $50,000 - $150,000 estimated, broader than Walker Tienkung's $65,000 - $115,000 range. Overlap exists in mid-price points. Price variations may reflect configuration options or included features.

D7 includes force limiting, collision detection, emergency stop, and redundant sensors. Walker Tienkung features force limiting, collision detection, emergency stop, and collaborative mode. Both share core safety mechanisms, with Walker Tienkung adding collaboration support.
