Let's begin with mechanical subsystems, essential for the physical capabilities of robotic construction equipment. Can anyone name some examples of actuators?
Are electric motors an actuator?
That's correct! Electric motors are a type of actuator. Actuators can also be hydraulic or pneumatic. They provide the movement needed for the robot to perform tasks. Why do you think variety in actuators is important?
Maybe because different tasks require different types of strength or precision?
Exactly! Each type of actuator has its strengths. For example, hydraulic actuators are great for heavy lifting. Now, what are end-effectors, and can anyone give an example?
They are tools attached to the robot, like a gripper or welding torch, right?
That's right! Grippers handle materials, while welding torches join parts together. Students, what could you infer about structural frames in relation to durability?
I guess they need to be strong enough to support all those mechanical parts without breaking.
Correct! The structural integrity allows robots to perform tasks safely. In summary, mechanical subsystems give robots the ability to physically interact with their environment through various actuators, end-effectors, and strong frames.

I think it's like the brain that processes information and controls the actuators.
Exactly! Microcontrollers manage inputs from sensors and send commands out. Now, what do we mean by feedback loops, like PID control?
It's a method of continuously adjusting the operations to reach a desired outcome?
Absolutely! Feedback loops are crucial for maintaining accuracy. Machine learning-based systems help robots adapt over time. Can anyone give an example of how that might be used?
