Robotics Formulas You Can Calculate

Kinematics Formulas

Kinematics describes robot movement, including speed, distance and travel time.

  • Distance = Speed × Time
  • Speed = Distance ÷ Time
  • Time = Distance ÷ Speed

Torque and Force Formulas

Torque and force calculations are essential when selecting motors, designing robot arms and determining mechanical loads.

  • Torque = Force × Lever Arm
  • Force = Mass × Acceleration
  • Force = Torque ÷ Lever Arm

Motor Speed and Rotational Motion

Rotational calculations help determine motor angular velocity, RPM and angular acceleration.

  • Angular Velocity = RPM × 2π ÷ 60
  • Angular Acceleration = Torque ÷ Inertia
  • Torque = Power ÷ Angular Velocity

Gear Ratio Calculations

Gear ratios help determine the relationship between input and output rotational speed and torque.

  • Gear Ratio = Output Teeth ÷ Input Teeth
  • Output Torque = Input Torque × Gear Ratio
  • Output Speed = Input Speed ÷ Gear Ratio

Electrical Power and Battery Calculations

Electrical calculations are useful for selecting batteries, estimating runtime and determining the power requirements of robotic systems.

  • Power = Voltage × Current
  • Energy = Power × Time
  • Current = Power ÷ Voltage
  • Battery Runtime = Battery Energy ÷ Power

Robot Wheels and Movement

Wheel calculations help estimate robot travel speed, wheel rotation and turning radius.

  • Wheel Circumference = π × Diameter
  • Wheel RPM = Robot Speed × 60 ÷ Wheel Circumference
  • Turning Radius = Distance Between Wheels ÷ 2
