KUAVO-MY vs D7: Key Differences in Humanoid Robots

KUAVO-MY is a compact biped, 166 cm tall and 55 kg, with 22 degrees of freedom, or 28 on the exhibition version with a moving head and dexterous hands. D7 is a semi-humanoid of 165 cm and 45 kg whose 30 degrees of freedom, or 50 with dexterous hands, all sit in an upper body on a wheeled base. They are almost the same height, but D7 puts all of its joints into its arms and torso, which reach 65 cm and place their tips to within 0.1 mm. KUAVO-MY spends its joints on legs, so it can walk where D7 rolls.

KUAVO-MY walks at 0.4 m/s, can run at up to 5 km/h and maps its surroundings with a 3D LiDAR and a depth camera. D7's 360° omnidirectional chassis reaches 2 m/s and copes with slopes of up to 10°. D7's top speed is five times KUAVO-MY's walking pace, which matters for carrying items across a building. KUAVO-MY's legs suit research into walking and demonstrations where a human-like gait is the point. KUAVO 4PRO (KUAVO-MY)'s mobility type is legged. Pudu D7's mobility type is wheeled-based.

KUAVO-MY's sensors are fully listed: an Orbbec Gemini 335L depth camera, a Livox Mid-360 3D LiDAR, an IMU, a six-microphone array that locates sounds in 360° and temperature sensors in its joints. D7's sensor hardware has not been listed by Pudu. KUAVO-MY is therefore the easier robot to evaluate and to build on for perception research. Ask Pudu for D7's sensor details before comparing the two on vision. KUAVO 4PRO (KUAVO-MY) has 22 degrees of freedom. Pudu D7 has 30 degrees of freedom, carries 10 kg and can deadlift 50 kg.

KUAVO-MY learns tasks by imitation from recorded demonstrations and answers questions through a large-model Q&A system, with AI running on an NVIDIA Jetson Orin NX. D7's control is layered: high-level planning decides the approach, low-level control responds to its sensors in real time, and Pudu says the robot improves its skills from data. KUAVO-MY suits teams that want to teach the robot new tasks themselves. D7 is designed to arrive with service skills such as lift operation already in place.

D7 runs far longer: its battery of more than 1 kWh gives over eight hours of continuous work. KUAVO-MY's 60 V, 6 Ah battery gives about an hour of walking and recharges in 1.5 hours or less. That is roughly eight times the runtime in D7's favour. KUAVO-MY works for sessions and demonstrations, while D7 can cover a full working day. Pudu D7 runs for more than 8 hours per charge. KUAVO 4PRO (KUAVO-MY) stands 166 cm tall and weighs 55 kg. Pudu D7 stands 165 cm tall and weighs 45 kg.

Leju aims KUAVO-MY at research labs, exhibition and shopping guidance, education and industrial trials. D7 is meant for service spaces and industrial sites, where Pudu has it riding lifts, carrying items and sorting goods. KUAVO-MY is a development and demonstration platform, while D7 is a working service robot. Choose KUAVO-MY for research, demonstrations and guided tours, or D7 for all-day service, lift operation and sorting on flat floors. KUAVO 4PRO (KUAVO-MY)'s listed uses include bipedal walking, obstacle traversal, tote carrying and customer guidance. KUAVO 4PRO (KUAVO-MY) runs for about 60 minutes per charge and recharges in 1.5 hours.

KUAVO-MY uses Leju's open ROS-based kuavo-ros-control stack for secondary development, and the KUAVO-MY edition runs the OpenHarmony-based KaihongOS. D7 runs Pudu's own embodied-AI system with high-level and low-level planning. KUAVO-MY is the clear choice for developers who want to modify control code. Pudu has not published D7's developer access, so ask before planning custom applications. KUAVO 4PRO (KUAVO-MY) runs leju's ROS-based kuavo-ros-control stack. KUAVO 4PRO (KUAVO-MY)'s safety features include low-battery audio alert and joint temperature monitoring. KUAVO 4PRO (KUAVO-MY)'s sensors include Orbbec Gemini 335L depth camera, Livox Mid-360 3D LiDAR, body IMU and joint temperature sensors.

KUAVO-MY has an emergency stop button on its body, a low-battery audio alert and temperature monitoring in its joints, which together guard against a drained pack or an overheated joint during long demos. D7 rides on a 360° omnidirectional wheeled base, so it does not have to balance on legs and has far less risk of falling on flat floors. Both are indoor machines: KUAVO-MY works in exhibition halls, shops, labs and factories, and D7 in service spaces and industrial sites with slopes up to 10°. D7's stable base is the lower-risk option around the public.

KUAVO-MY is listed at $50,000 to $150,000 and D7 at $100,000 to $150,000, so KUAVO-MY starts at half the price and ends in the same place. At the low end it is the cheaper way into a full-size walking humanoid with an open ROS-based stack. D7's higher floor buys over eight hours of continuous operation, a 10 kg lift per arm and elevator operation for service work. For research budgets KUAVO-MY is the better value; for working service roles D7 offers more per dollar. Pudu sells D7 through its sales team.
