Robotics Calculators
Free online calculators for robotic kinematics, motion planning, and mechanism design.
Inverse Kinematics Calculator (2-Link Planar Arm)
Compute joint angles θ₁ and θ₂ to reach a target (x,y) with a 2-link planar arm. Returns both elbow-up and elbow-down solutions or reports unreachable.
Forward Kinematics Calculator (2-Link Planar Arm)
Compute end-effector position from joint angles for a 2-link planar robot arm. Pair with inverse kinematics for full motion-planning workflows.
Wheel Odometry Calculator (Differential Drive)
Estimate robot position from left and right wheel encoder ticks. Calculates distance, heading change, and new pose for a differential drive robot.
