UGV Design Space

Explore mass, range and payload trade-offs for a ground vehicle.

UGV Design Space Explorer

Interactive tradeoffs for wheel count, travel, damping, tire, speed & terrain. Coarse models for concept selection.

Parameters

Wheels8.00

Curb Mass (kg)220.00

Payload (kg)40.00

Wheel OD (m)0.48

Suspension Travel (m)0.20

Damping Ratio ζ0.18

Terrain Corr. Length λ (m)1.20

Speed (m/s)4.00

Actuation Authority (supply factor)0.80

Cost Baseline (USD)4002.00

Performance (coarse)

Natural freq fn

0.79Hz

Ride accel RMS

0.170g

Step capability

0.263m

Stability (SSF)

1.13

Ground pressure

69.0kPa

Power proxy

0.21kW

DOE Pareto — Cost vs Comfort (lower is better)

Ride vs Speed (A=0.05 m, λ=1.20 m)

Pinned designs (0)

Arch	Wheels	Speed m/s	Travel m	Cost $	Comfort g	Step m	SSF	Power kW

Assumptions

Single-DOF bounce model + base excitation; rough but useful for ranking.
Cost scales with mass and actuation authority; baseline from BOMs.
Step metric ≈ 0.34·wheelOD + 0.5·travel (geometry + traction limited).

Tips

Bigger wheels reduce Crr and improve step; keep SSF ≥ 1.1 for stability.
Target ride acceleration < 0.25 g-rms for sensor payloads.
For MIL overlays, use 38999 bulkheads and 1275/461 front-end on ECUs.

Export DOE and pinned designs as CSV; paste into Sheets or a report. Screenshot charts directly.
