Quadruped Robot CD-A2
Product Details
Constructed from high-quality aluminum alloy and engineering-grade plastics, the A2 achieves an uncompromising balance between strength and flexibility. Measuring 820 x 440 x 570 mm and weighing only 31 kg (37 kg without batteries), you might be surprised to find that this incredibly robust and durable robot can support the weight of an adult (100 kg).
Considering applications such as reconnaissance, exploration, investigation, and rescue, the A2 robotic dog can traverse the ground quickly-reaching speeds of up to 5 m/s, easily navigating obstacles up to 1 meter high, while also effortlessly stepping and sliding.
Furthermore, the CD A2 is equipped with dual LiDAR sensors for a full 360° field of view and a high-definition camera with forward-facing light, making it an ideal robot for inspection and search operations.
