Robot Joint Actuator Torque-Speed Envelope (2D)

Interactive 2D robot-joint simulator: a torque-speed operating envelope (adjustable stall torque and no-load speed) clamps the actual torque and speed the joint can achieve while tracking a commanded trajectory, with a live torque-speed scatter trace and a load-inertia sweep verifying that heavier loads spend more time constrained.

A 2D robot-arm joint driven toward a commanded target angle, where every instant's required torque is computed from real joint dynamics (τ = I·α + b·ω) and then saturated to whatever the actuator's torque-speed envelope — set by an adjustable stall torque and no-load speed — can actually deliver. Watch the live torque-speed scatter hug the envelope boundary whenever the commanded motion outruns the actuator, and run the load-inertia sweep to verify numerically that heavier loads spend more time constrained.

⚙ Under the hood

An interactive 3D winch-and-load simulator comparing how a brushed DC motor, a geared servo actuator, and a hydraulic cylinder each deliver torque and speed under a hanging load, with a live torque-speed operating-point chart.
