planar robot jacobian singularity indicator calculator online

Use planar robot jacobian singularity indicator online for link1 mm, link2 mm, joint2 deg. Zero indicates a kinematic singularity in the ideal planar two-link model. 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, joint2 deg. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
link1 mmMain input. Positive values. 200
link2 mmOption. Positive values. 150
joint2 degOption. Signed finite values. 30

Calculation method

jacobian_determinant_mm2 = link1_mm*link2_mm*sind(joint2_deg) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply planar robot jacobian singularity indicator to the case below, keeping the displayed units and assumptions. Zero indicates a kinematic singularity in the ideal planar two-link model.

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

  • Zero indicates a kinematic singularity in the ideal planar two-link model. 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.
