Forward Kinematics — Delta Picker (1 kg)
2-link planar FK for a delta picker (1 kg): TCP position and reach from joint angles and link lengths.
Delta robots invert the architecture — motors sit still in the frame and three light parallel links fly. The 2-link model approximates one arm chain's side view: upper arm 350 mm driven, 800 mm passive rods. Light moving mass is the entire secret of 200 picks/minute.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Forward Kinematics — Delta Picker (1 kg)
Forward Kinematics — Delta Picker (1 kg) computes the governing relationship x = L₁cosθ₁ + L₂cos(θ₁+θ₂) · y = L₁sinθ₁ + L₂sin(θ₁+θ₂) live as you type. Delta robots invert the architecture — motors sit still in the frame and three light parallel links fly. The 2-link model approximates one arm chain's side view: upper arm 350 mm driven, 800 mm passive rods. Light moving mass is the entire secret of 200 picks/minute. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Forward Kinematics — Delta Picker (1 kg)
- 1Enter your values — Link 1 length L₁, Link 2 length L₂, Joint 1 angle θ₁, Joint 2 angle θ₂ (sensible defaults are pre-filled).
- 2Read the live results: TCP X, TCP Y, Radial distance, Max reach.
- 3Check the "with your numbers" line to see x = L₁cosθ₁ + L₂cos(θ₁+θ₂) · y = L₁sinθ₁ + L₂sin(θ₁+θ₂) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Forward Kinematics — Delta Picker (1 kg)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula x = L₁cosθ₁ + L₂cos(θ₁+θ₂) · y = L₁sinθ₁ + L₂sin(θ₁+θ₂) with authoritative sources cited on the page (Craig, J., Introduction to Robotics: Mechanics and Control, 4th ed.; Siciliano & Khatib (eds.), Springer Handbook of Robotics, 2nd ed.)
- ✓Delta robots invert the architecture — motors sit still in the frame and three light parallel links fly.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the forward kinematics — delta picker (1 kg) use?+
It evaluates x = L₁cosθ₁ + L₂cos(θ₁+θ₂) · y = L₁sinθ₁ + L₂sin(θ₁+θ₂), exactly as published. Sources: Craig, J., Introduction to Robotics: Mechanics and Control, 4th ed.; Siciliano & Khatib (eds.), Springer Handbook of Robotics, 2nd ed.. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Delta robots invert the architecture — motors sit still in the frame and three light parallel links fly. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
When is this calculator the right tool for the job?+
2-link planar FK for a delta picker (1 kg): TCP position and reach from joint angles and link lengths. A free industrial robot kinematics & cell design tool. The 2-link model approximates one arm chain's side view: upper arm 350 mm driven, 800 mm passive rods. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
