Robotics Robot Arm in Robotics
Kinematics relates joint angles to end-effector (gripper) position. Forward kinematics: given joint angles, calculate end position. Inverse kinematics: given desired position, find required angles.
A 2-link arm with lengths L1, L2 and angles θ1, θ2: end X = L1·cos(θ1) + L2·cos(θ1+θ2), Y = L1·sin(θ1) + L2·sin(θ1+θ2).
Inverse kinematics is harder — often solved numerically. For simple arms, geometric approach works: solve using law of cosines.

// Forward kinematics: 2-link arm float L1 = 10, L2 = 8; // Segment lengths (cm) float theta1 = 45; // Degrees float theta2 = 30; float rad1 = radians(theta1); float rad2 = radians(theta2); float endX = L1*cos(rad1) + L2*cos(rad1+rad2); float endY = L1*sin(rad1) + L2*sin(rad1+rad2);
