Teleoperation in HRC
Unlock Audio Lesson
Today, we explore teleoperation as a key type of HRC. Can someone explain what teleoperation entails?
Isn't teleoperation when humans control robots from a distance, especially in dangerous areas?
Exactly! It allows operators to control robots remotely using specialized controls, enhancing safety in hazardous situations. Think of it as a way to have humans 'in control' without being on-site. A useful memory aid is 'T for Teleoperation = T for Tension Relief' since it reduces danger.
But how does this work practically in tunneling?
Great question! In tunneling, operators might control robots to inspect tunnels or handle responsibilities that might expose them to toxic gases or poor visibility.
What kind of controls are used?
Typically, operators use joysticks or haptic feedback devices that mimic the motions required for effective robot operation. Remember, 'Haptic is to Touch' — it enhances the control experience!
Shared Autonomy in HRC

Next, let's talk about shared autonomy. Who can summarize what it means?
I think shared autonomy means the robot does most tasks, but the human can step in if needed?
Well said! It allows robots to handle routine tasks autonomously while humans intervene during exceptions. This reduces human workload and leverages robot capabilities.
Can you give an example of where this might be used?
In tunneling, a robot might autonomously monitor geological conditions, notifying the human operator only if something unusual occurs. Think of it like having a robot butler — it takes care of chores but lets you know if there’s a mess!
What if the robot malfunctions?
That’s where human intuition comes in! The human can quickly take control if needed. A mnemonic to remember this is 'S for Safety in Shared'.
Physical Collaboration in HRC
Unlock Audio Lesson
Finally, let’s discuss physical collaboration. What can anyone tell me about this type of HRC?
Isn't that when robots work side by side with humans?
Correct! Physical collaboration involves robots assisting humans in managing tools or heavy components, which helps reduce strain and improve productivity.
What tools might a robot handle?
For example, a robotic arm could help lift heavy steel beams while a worker positions them accurately. It’s important to remember that teamwork is improved through robotics — think of the acronym 'C for Collaboration = C for Construction'!
Are there risks in this collaboration?
Yes, always! Safety mechanisms, like proximity sensors, are essential to ensure that both robots and humans are aware of each other's presence.

Quick Overview
Standard
The main types of HRC in tunneling include teleoperation, where humans control robots remotely; shared autonomy, which allows robots to manage routine tasks with human oversight; and physical collaboration, where robots assist humans directly in handling materials. Each type enhances efficiency and safety in complex construction environments.

Types of HRC
Human-Robot Collaboration (HRC) is essential in underground construction to enhance productivity and safety. This section identifies three main types of HRC:
1. Teleoperation: This involves human operators remotely controlling robotic systems, particularly in hazardous conditions where direct human presence is dangerous. Teleoperation allows the human operator to use specialized controls to direct the robot's actions, ensuring safety and precision.
- Shared Autonomy: In this model, robots perform routine tasks independently while humans step in only when exceptions arise or decisions are required. Shared autonomy provides a balance between automation and human intervention, improving efficiency while still relying on human judgment when necessary.
- Physical Collaboration: This type of HRC involves robots that work side by side with humans, assisting them in handling heavy equipment or structural elements. Physical collaboration enhances the capabilities of human workers, allowing them to complete more complex tasks with reduced physical strain.
These models represent significant advancements in tunneling technologies, aiming to maximize both productivity and safety while acknowledging that human expertise remains essential.

• Teleoperation: Human operators remotely control robots in unsafe or inaccessible areas.
Detailed Explanation
Teleoperation refers to the process where a human operator controls a robot from a distance. This means that the operator can be safe and secure while still performing tasks that would be too dangerous or difficult to do directly. For instance, in tunnel construction, teleoperation can allow a human to control machinery in a space where risks from falling rocks or flooding exist, making it safer for the worker.
Examples & Analogies
Imagine a video game where you control a character from a distance, guiding it through obstacles. Just like a gamer uses a controller to navigate a character in a virtual world without being physically present, a human operator uses teleoperation to control a robot that is working in dangerous environments.

• Shared Autonomy: Robot handles routine tasks; human intervenes during exceptions.
Detailed Explanation
Shared autonomy is a collaborative approach where robots and humans work together on tasks. In this model, robots can perform regular or repetitive tasks autonomously, while humans step in to make decisions or control the robot when unexpected situations occur. This combination enhances efficiency since the robot takes care of the mundane tasks, allowing human operators to focus on more complex decisions.
Examples & Analogies
Think of a chef and an assistant in a kitchen. The assistant can chop vegetables or mix ingredients (routine tasks) while the chef focuses on creating the dish and adjusting flavors (exceptional tasks). Just like how the chef steps in for creative input, humans can direct robots when unique situations arise.

• Physical Collaboration: Co-working robots assist humans in handling heavy tools or segments.
Detailed Explanation
Physical collaboration involves robots that are designed to work alongside humans, often assisting them with heavy lifting or complex tasks. Such robots are equipped with tools to help manipulate large equipment or materials, making work safer and more efficient. By sharing the workload, humans can avoid injuries and increase productivity.
Examples & Analogies
Consider a construction site where a human worker uses a robotic exoskeleton to lift heavy beams. The exoskeleton provides strength and stability, allowing the worker to lift much more than they could on their own. Similar to this, collaborative robots (cobots) support workers by sharing the physical demands of their tasks.
