    RobotControlSystem(int jointCount) {
        for(int i = 0; i < jointCount; ++i) {
            joints.push_back(RoboticJoint());
        }
    }

            // Here we could implement a sophisticated control algorithm
            // For simplicity, we just demonstrate the interface
            double controlSignal = joint.position * 1.2 - joint.velocity * 0.5 + joint.torque * 0.1;
            // In a real robot, we would send this signal to the motor drivers
            std::cout << 'Control signal to joint: ' << controlSignal << std::endl;
        }
    }
};

int main() {
    RobotControlSystem robot(3); // Create a robot with 3 joints
    
    // Example sensor data for the robot's joints
    std::vector<double> sensorPositions = {10.0, 20.0, 30.0};
    std::vector<double> sensorVelocities = {1.0, 1.5, 2.0};
    std::vector<double> sensorTorques = {5.0, 10.0, 15.0};

    // Simulate receiving the sensor data
    robot.receiveSensorData(sensorPositions, sensorVelocities, sensorTorques);

    // Apply control to the robot based on the sensor data
    robot.applyControl();

    return 0;

Code Explanation:

The program provided is a C++ example simulating the control system for a robotic application, specifically demonstrating how a robotic control system can receive sensor data, update the states of the robotic joints, and apply control signals based on the sensor data.

Let’s break it down:

• First, we include the necessary headers.
• The RoboticJoint class represents a single joint in a robot which has a position, velocity, and torque. It includes an update method to modify the joint’s state.
• The RobotControlSystem class represents the robot’s control system. It contains a vector of RoboticJoint objects.
  • The constructor initializes the system with a specific number of joints.
  • The receiveSensorData method simulates receiving new data from sensors and updates the states of the joints using the update method from the RoboticJoint class.
  • In applyControl, we calculate and output a simple control signal for each joint based on its position, velocity, and torque.
• In main, we create an instance of the RobotControlSystem with three joints, simulate receiving sensor data, and call applyControl to apply control to the robot.

The architecture of the program is modular, separating the concerns of joint state representation and control system logic, following principles common in robotic applications. The control algorithm used here is a placeholder and in a real-world scenario, would be a sophisticated PID controller or similar.

While this example is simplified, in an actual robotics application, the control signals would interact with hardware interfaces to move the joints of the robot. The concept illustrated here focuses on the structure and flow of such a program, which is foundational in robotics programming for automation and control.
