🦾 Home and service robotics: Robots for everyday life: From vacuum cleaner to personal assistant

Introduction

Home and service robotics is a field that defines a robot as a helper - whether for the home (cleaning), commercial spaces (office logistics) or for personal assistance (care for the elderly).

While an industrial robot is fixed and repeats a single task, a service robot is mobile, collaborative, and versatile. It must be able to navigate unpredictable, messy environments and interact with people more safely than anyone else.

This area is a driving force for humanoid robotics (see Optimus vision), but in practice today simple, specialized machines that deliver immediate value dominate.

⚙️ Problem: Cost of time and complexity of the environment

The main problem that service robots solve is the cost of time spent doing routine, boring, or physically demanding work in an unmanaged environment.

What it looks like in practice: An office building manager pays a cleaning company to manually scrub the floors. A hospital nurse spends her time delivering laundry instead of caring for patients. A senior needs help opening lockers.

The most common problems and losses:

• High cost of manual routine: Cleaning is expensive, repetitive, and non-scalable.
• Missing staff: Lack of caretakers, cleaners or delivery people within the premises.
• Monotonous workload for people: Physically strenuous handling of loads or chemicals during cleaning.
• Complexity of manipulation: The most difficult thing for personal assistance is delicate manipulation of objects in a chaotic environment (e.g., in the kitchen).

🤖 Solution: From a specialized robot to a personal assistant

Service robotics today is divided into two main categories.

1. Specialized mobile robots (Commercial/B2B)

• Examples: Robotic lawnmowers (Husqvarna Automower), robotic vacuum cleaners for the home (Roomba), disinfection robots in hospitals (UV-C disinfection).
• Function: They take on one monotonous task and do it autonomously.
• The biggest boom: Autonomous delivery trucks (AMR) for delivery in hospitals, hotels and offices, which autonomously carry food, laundry or documents.

2. Personal and Humanoid Robots (Assistance/B2C Vision)

• Examples: SoftBank Pepper (information and interaction), Tesla Optimus/Figure (future vision).
• Function: Highly mobile, collaborative machines designed to interact with humans and handle a wide range of unguided tasks (open a door, hand an object, carry a conversation).
• Status in 2025: Still mostly in the research, development and pilot phase. The biggest obstacle is still motion intelligence in an unknown environment (so-called Embodied AI).

📈 Key benefits: Savings and Quality of service

• 1️⃣ Guaranteed efficiency (Commercial cleaning)
  Robotic cleaning (floor scrubbers) works faster, more efficiently and more consistently than human power, at a lower hourly rate.
• 2️⃣ Improving the quality of care (Healthcare)
  AMR delivery robots free nurses from logistics so they can focus on direct patient care.
• 3️⃣ Immediate availability (B2C)
  Robotic vacuum cleaners and lawn mowers handle routine tasks automatically, becoming a common part of the household (the greatest commercial success of robotics outside of industry).
• 4️⃣ Future solutions to the demographic crisis
  In the future, assistive robots (humanoid or wheelchair-mounted) will be critical for caring for an aging population.

🧠 What does a real deployment look like (Typical scenario)

Scenario: Medicine delivery in a hospital.

• ➡️ Before: A nurse spends 2 hours a day transporting medications and laundry between wards.
• ➡️ After deployment: The delivery AMR (equipped with sensors and a map) takes over all transportation. A nurse on the ward loads the medication into the robot, sets a destination, and the AMR autonomously moves through the corridors, avoiding people, and takes the elevator to another floor.
• ➡️ Result: The nurse gets 2 hours of pure time back for patient care. Logistics is more efficient and error-free.

📦 Technologies that drive assistance

For service robotics, the most important things are a mobile platform and flexible arm ends.

• Autonomous Mobile Platforms (AMR): These systems are sold in the millions today. They use LiDAR and SLAM algorithms for navigation.
• Collaborative Arms on Carts: Future assistive robots will often utilize a standard, safe robot arm, such as the UR3e, mounted on a mobile base (AMR) to reach shelves.
• Gentle and safe grippers: For handing a glass, opening a door, or picking up a small object, grippers with adaptive grip, such as the OnRobot RG2/RG6, are key.

❓ Frequently Asked Questions (FAQ)

How is the safety of an assistive robot ensured? Service robots (mainly AMR) are equipped with multi-level sensors – LiDAR, ultrasound and touch sensors. They are designed to stop before contact occurs.

How does a humanoid robot manage to open a door? Humanoid robots combine a vision system (cameras) to recognize the handle and force/torque sensors in the joints so that the hand applies the correct pressure and load on the mechanism.

When will robots routinely assist in homes? Fully autonomous humanoids that are fully multifunctional (like C-3PO) are 5–10 years away. Specialized assistive robots on carts (for cleaning, serving, delivery) are available today.

🧭 Conclusion

Service robotics is divided into reality (AMR for logistics, robotic vacuum cleaners) and vision (fully autonomous assistants). However, key technologies – mobility, collaborative arms and smart grippers – are rapidly evolving in both directions.
