Engineering tools

Free calculators that turn the formulas covered in Physical AI Portal articles into tools you can run with your own numbers. Every tool is available in eight languages and lists the sources behind its formulas, the date they were last verified, and related articles.

On-Vehicle VLA Compute, Latency & Storage Budget Calculator (Vision vs Vision+LiDAR)

Simulation & AI Compute Infra Configure VLA parameters, multi-camera & LiDAR tokens, streaming KV cache reuse, and automotive SoCs (DRIVE Thor, Orin, Journey 6P, MDC) to size onboard compute, latency, storage, and fleet telemetry offload. Free 8 languages Open
