Cassie height describes the vertical dimensions and proportions of the Cassie robot developed by Agility Robotics. Understanding these measurements helps teams integrate the robot into human-centric workspaces and design safe navigation paths.
Engineers and planners use standardized values for Cassie height to evaluate door clearances, elevator availability, and human-robot interaction zones. The following summary outlines key dimensional specifications at a glance.
| Height Reference | Metric Value | Imperial Value | Relevance |
|---|---|---|---|
| Standing Hip Level | 1.22 m | 48 in | Everyday interactions and side access |
| Standing Shoulder Level | 1.65 m | 65 in | Upper reach and equipment clearance |
| Maximum Height with Stretch | 1.75 m | 69 in | Tall shelf or overhead bin access |
| foot to hip | 0.61 m | 24 in | Stable base for load handling |
Engineering Design Around Cassie Height
The Cassie height specification guides mechanical layout, sensor placement, and center of mass control. Designers align leg segments and torso components so that the robot maintains stability while reaching for objects at various elevations.
Clearance envelopes derived from Cassie height define safety margins near fragile fixtures or overhead obstructions. Teams simulate multiple scenarios to confirm that planned paths keep the machine within validated spatial limits.
Navigation in Human Spaces
Cassie height influences how the robot perceives and shares corridors, doorways, and stair landings with people. Operators translate dimensional data into speed and trajectory rules that minimize sudden movements in crowded areas.
For multi-floor operations, Cassie height determines whether standard elevators and ramps can accommodate the robot without modifications to existing infrastructure. Facilities teams verify dimensional compatibility before deployment schedules are finalized.
Task Planning and Use Cases
In inventory and inspection roles, Cassie height maps directly to reachable zones on shelving units and equipment racks. Planners segment tasks by elevation band to maximize throughput while preserving ergonomic compliance.
During exterior or rough terrain operations, the same dimensional profile supports stable traversal over uneven ground and small obstacles. Engineers balance Cassie height against payload capacity to ensure safe climbing and descending on gradients.
Operational Best Practices
- Map task locations to vertical bands aligned with Cassie height specifications.
- Validate door, elevator, and corridor clearances using measured hip and shoulder dimensions.
- Program speed and stopping points to account for the robot’s reach envelope.
- Schedule periodic spatial audits to ensure clearances remain sufficient after layout changes.
FAQ
Reader questions
How does Cassie height affect door selection for robot access?
Standard door clearances must exceed Cassie height at the shoulder level to allow safe passage; teams typically specify doors with at least 305 mm of additional vertical space.
Can Cassie fit inside standard passenger elevators?
Yes, Cassie height is compatible with most building elevators, but planners must also verify width and doorway alignment for unassisted entry and exit.
What clearance should be kept above Cassie during overhead operations?
A minimum of 150 to 300 mm above the maximum height with stretch is recommended to protect sensors and prevent contact with fixtures.
How does Cassie height influence human-robot spacing in shared areas?
Workspaces should provide lateral margins of at least 600 mm around Cassie to accommodate its height profile and allow comfortable human movement.
