LiDAR for robot dogs & quadruped robots
Legged locomotion means constant shock and vibration, and a body that occludes part of the sensor's own field of view. ZVISION's NZ series was built with both in mind.
Which ZVISION LiDAR is best for robot dogs / quadruped robots?
For robot dogs / quadruped robots, ZVISION recommends the NZ1 and NZ3. NZ1: Ultra-wide-FOV LiDAR for mainstream robotics — 40 m @10% reflectivity, 240° × 80° FOV. NZ3: Mid-range wide-FOV LiDAR for outdoor robotics — 70 m @10% reflectivity, 240° × 80° FOV. Ultra-wide coverage: NZ1's 240° horizontal and 80° vertical FOV cut the blind spot at the mount point and around the robot's own legs.
Recommended sensors
Where LiDAR fits
- 3D terrain perception on uneven, outdoor ground
- Navigation with minimal blind spots around the robot's own legs and body
- Obstacle avoidance during dynamic gait
- Mapping in unstructured, outdoor environments
What to look for
Ultra-wide coverage
NZ1's 240° horizontal and 80° vertical FOV cut the blind spot at the mount point and around the robot's own legs.
Shock and vibration tolerance
The sensor has to keep working through the impact and vibration profile of a walking or trotting gait.
Combined near-field and long-range coverage
One sensor needs to handle both far-field route planning and close-in foot placement.
In the field: Reference architecture used on quadruped platforms requiring all-terrain 3D perception with a single forward-mounted sensor.
Frequently asked
Can one LiDAR handle both navigation and near-field obstacle avoidance on a robot dog?
Yes — NZ1's 240°×80° field of view is specifically sized to cover long-range navigation and near-body blind spots with a single unit, avoiding the need to pair a 3D LiDAR with a separate depth sensor.
Is the NZ series suitable for the vibration of a legged gait?
Yes — the NZ series is already deployed on quadruped platforms and is designed for the shock and vibration of walking and trotting gaits.
