Transparent estimates

Engineering Calculators

Show the formula, understand the assumptions, then validate the complete system.

METRIC FIRST

PRELIMINARY DESIGN / NOT PRODUCT VALIDATION

Make the variables visible before choosing hardware.

Every calculator keeps metric units first, explains limitations and produces a copyable engineering estimate.

Total mass, nominal distribution and conservative design load.

Rolling, slope and acceleration force on a cart.

Force per drive wheel and required wheel torque.

Nominal energy, usable energy and estimated runtime.

A conditional guidance range with explicit tradeoffs.

Build an engineering requirement profile before viewing HAION solutions.

Define route, load, packaging and control requirements before PAS selection.
