Calculators

All seven calculators are live. Each one follows the load from the motor through the joints, and opens on example numbers. Change them to match your robot.

Live

1. Belt reduction to rack and pinion

Stall torque flows down the chain; every joint gets a check

Live

2. Arm on a pivot

Gravity torque peaks at horizontal; the gearbox and hub carry it

Live

3. Elevator

Hard stops spike rigging tension well past steady lift

Live

4. Intake rollers

A jammed game piece stalls the motor; the bore and breaker take it

Live

5. Flywheel shooter

Flywheel inertia loads the belt on spin-up and the bore on braking

Live

6. Drivetrain

Wheels slip before motors stall, so traction sets the real load

Live

7. Long shaft vs split shafts

Every inch of shaft adds twist; drive point and splits change it
