Servo Angle from PWM
Convert a servo motor's PWM pulse width into the corresponding angle, angle = (pulse − 1000)/1000 · 180°, in the hobby standard where 1000 µs ≈ 0°, 1500 µs ≈ 90° (center) and 2000 µs ≈ 180°. Hobby and robotics servos are commanded by this pulse width, typically at 50 Hz. Knowing the relation helps to calibrate and program movements. Enter the pulse width in microseconds.

Ângulo de servo por PWM
Os servomotores de modelismo e robótica não são comandados por tensão ou corrente, mas pela largura de um pulso. O padrão de fato: um pulso repetido a ~50 Hz, cuja duração define o ângulo — 1000 µs ≈ 0°, 1500 µs ≈ 90° (centro) e 2000 µs ≈ 180°. A conversão é ângulo = (pulso − 1000)/1000 · 180°. Dentro do servo, um circuito compara essa largura com a posição lida por um potenciômetro no eixo e aciona o motor até zerar a diferença — um pequeno laço de controle fechado em cada servo. (Os limites exatos variam por modelo; alguns usam 500–2500 µs para 0–180°.) Saber a relação é essencial para calibrar braços robóticos, gimbals e controles de voo. Informe a largura do pulso em microssegundos.

Servo Torque for Arm
Calculate the static torque a servomotor needs to hold a horizontal arm, T = m·g·L, from the tip mass m, gravity g (9.81 m/s²) and the arm length L. The result, in N·m, is the minimum torque the servo must provide to keep the arm horizontal against the load weight — the most unfavorable position. It is essential in designing robotic arms, grippers and servo-driven mechanisms, sizing the motor with a safety margin over this value. For arms with their own mass, the center of mass is used. Enter the mass and the arm length.
Trapezoidal Profile Time
Compute the total time of a motion with a trapezoidal velocity profile, t = d/Vmax + Vmax/a, adding the cruise-velocity time to the acceleration and deceleration phases. It is the most common motion profile in motors and robots: accelerate to maximum speed, hold constant and decelerate. Enter the distance, the maximum velocity and the acceleration (assuming equal acceleration and deceleration).
Grain Conical Pile Volume
Calculate the volume of a conical pile of granular material formed by free pouring, V = (π/3)·r³·tan(θ), from the pile base radius r (m) and the material's angle of repose θ (degrees). When granular material is freely poured onto a surface, it naturally forms a CONE whose side slope is the angle of repose — a characteristic property of each material (dry sand ~30-35°, grain ~25-30°, crushed stone ~37-40°) reflecting inter-particle friction. Since the cone height is h = r·tan(θ), the cone volume (1/3·π·r²·h) becomes (π/3)·r³·tan(θ), a function of radius and angle of repose only. This is widely used in practice to estimate, from a survey or base-radius measurement, the volume (and with density, the mass) of open stockpiles — piles of grain, sand, crushed stone, coal, ore, fertilizer in yards and warehouses. It is the basis of bulk-material inventory in piles, a quick alternative to weighing. It also guides stockyard area and height sizing and bulk-warehouse design. For elongated piles (prismatic with conical ends), add the central part. Enter the base radius and the angle of repose.
