two link robot forward kinematics calculator online
Use two link robot forward kinematics online for link1 mm, link2 mm, joint1 deg, joint2 deg. Planar revolute joints; second angle is relative to the first link. Idealized robotics model using explicit dimensions and conventions. Obstacles, structural limits and control-system safety are not determined.
How to use it
Enter link1 mm. Set link2 mm, joint1 deg, joint2 deg. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
x_mm = link1_mm*cosd(joint1_deg)+link2_mm*cosd(joint1_deg+joint2_deg); y_mm = link1_mm*sind(joint1_deg)+link2_mm*sind(joint1_deg+joint2_deg) (^ means exponentiation; trig functions ending in d use degrees).
Worked examples
Apply two link robot forward kinematics to the case below, keeping the displayed units and assumptions. Planar revolute joints; second angle is relative to the first link.

}Choose the right tool
Use forward kinematics to map joints to a position and inverse kinematics for reachable position targets. Encoder resolution is not mechanical accuracy; supplied motion and gripping models do not certify a robot cell.
Limitations and common mistakes
- Planar revolute joints; second angle is relative to the first link. Idealized robotics model using explicit dimensions and conventions. Obstacles, structural limits and control-system safety are not determined.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
