Light but Powerful: A Beginner’s Guide to Torque Calculation for Selecting Small Actuators
- When building a lightweight robotic arm, selecting the right motor is crucial to ensure proper movement.
- Torque calculation is essential for designing ultra-lightweight arms with a payload capacity under 100 grams.
- Torque, measured in N·m, represents rotational force, crucial for movement in robotic arms.
- The torque required for a robotic arm is calculated based on the angle of the arm, with sin(θ) affecting the torque.
- The torque needed can increase significantly as the arm moves from a horizontal to a vertical position.
- It is common for required torque to double, triple, or more as the arm posture changes, posing a challenge in lightweight design.
- Strategies for lightweight optimization can help manage torque and achieve a successful design for lightweight robotic arms.
- On June 23, 2025, a journey into lightweight robotic arms is initiated to challenge the notion that robotics is exclusive to big companies.
- The goal is to pioneer the future of robotics with the help of mathematics and basic tools.
- Collaboration is invited to build the future of robotics together.
