Testing & Evaluation
1. Performance Criteria
The base subsystem is evaluated against the following performance criteria, derived from the system-level requirements:
| ID | Criterion | Target |
|---|---|---|
| RM-1 | Stability under punching loads | Remain upright under worst-credible punching loads (FoS ≥ 1.5) |
| RM-2 | Preserve user footwork space | Zero foot contact with base during active stance and pivot drills |
| BAS-AC-1 | Rigid mechanism mounting foundation | Provide a flat, rigid geometric datum for the mechanism stack |
| RM-3 | Practical transport | Support 1-person tip-and-roll transport between locations |
| N/A | Long-term structural solution | Clear load path, suitable fabrication, effective corrosion mitigation |
2. Test Procedures
Test 1: Physical Tipping Test (RM-1)
- Setup: Robot fully assembled and adjusted to maximum height extension.
- Procedure: Apply worst-case horizontal punch loads to the upper striking targets (head and torso).
- Success Criteria: The robot must remain upright without the base lifting or the system overturning.
Test 2: Footwork Clearance Assessment (RM-2)
- Setup: Robot placed in normal operating environment.
- Procedure: User executes a full range of boxing footwork around the robot, including forward steps, backward retreats, and lateral pivots in both orthodox and southpaw stances.
- Success Criteria: Zero interference or contact between the user's feet and the robot's base.
Test 3: Transport & Relocation Test (RM-3)
- Setup: Robot fully assembled on typical gym flooring (e.g., rubber mats).
- Procedure: A single operator grips the vertical column, tilts the robot backward onto its rear transport wheels, and rolls it to a new location.
- Success Criteria: The robot can be safely and smoothly relocated by one person without requiring disassembly.
Test 4: Structural & Mounting Inspection (BAS-AC-1)
- Setup: Fabricated base-feet assembly.
- Procedure: Inspect the welded frame and mounted plate for rigidity, flatness, and application of corrosion protection (primer/paint/cavity wax). Verify against CAD mass properties.
- Success Criteria: Welded steel base provides a clear, rigid load path superior to early prototypes, with a low vertical centre of mass.
3. Results
At present, the base subsystem has been fully validated through physical testing, confirming its success in concept, geometry, structural stability, and practical portability.
| ID | Criterion | Measured Result | Status |
|---|---|---|---|
| RM-1 | Stability under punching loads | Remains completely stable under physical full-extension punch impacts. Validated analytical overturning model. | |
| RM-2 | Preserve user footwork space | Zero foot contact observed during orthodox and southpaw pivots. Trapezoidal geometry preserves front zone. | |
| BAS-AC-1 | Rigid mechanism mounting | Plate observed to be flat and rigid. Welded steel base clearly superior to temporary wooden board. | |
| RM-3 | Practical transport | Single operator successfully tilted and relocated the assembled robot. | |
| N/A | Corrosion mitigation | Strategy defined and applied. Long-term performance pending field exposure. |
