The Hidden Agenda of Household Robots: Prioritizing Values Over Tasks

In the evolving landscape of household robotics, task completion has long been the primary measure of a robot's effectiveness. Yet, real domestic environments present nuanced challenges that extend beyond simply finishing chores. With the introduction of RobotValues, a new benchmark evaluating 10,000 value-conflict scenarios, a spotlight is cast on these machines' ability to balance human values such as autonomy, efficiency, and social appropriateness.

Understanding RobotValues

The RobotValues benchmark aims to test how household robots navigate complex situations that require prioritizing competing human values. It offers an extensive database of scenarios, each illustrated by a realistic household image featuring multiple plausible robot actions. These actions aren't just about completing tasks. they're about choosing actions that resonate with different human values.

Constructed through a combination of large language model (LLM)-assisted scenario generation, stakeholder-grounded value extraction, and image generation, RobotValues embodies an innovative approach to scenario creation. The automatic quality control ensures the benchmark remains a reliable measure of a robot's value preferences.

Revealing Default Preferences

Testing with RobotValues has unveiled that even the most sophisticated visual-language models (VLMs) used in robotics display inherent biases in their decision-making. These models tend to favor actions prioritizing safety and accommodation, often neglecting those that emphasize privacy. Surprisingly, when prompted to prioritize conflicting values, these models often struggle to override their default preferences, erring in their choices 80% of the time.

This revelation begs the question: In a future where household robots are commonplace, how do we ensure they align with the diverse values of human society? It's not merely about creating efficient machines, but about crafting robots with the sensitivity and adaptability to navigate the moral complexities of everyday life.

Beyond Task Completion

The significance of RobotValues extends far beyond technical evaluation. It challenges the robotics community to rethink how success is measured. Robots shouldn't just tick off tasks from a to-do list. Instead, their ability to make nuanced decisions in the face of conflicting human values is critical.

The deeper question lies in whether we can engineer robots that truly understand and prioritize human values dynamically. As robots become increasingly integrated into our personal spaces, the demand for them to act in ways that reflect and respect human priorities becomes ever more urgent.

In this context, RobotValues doesn't just offer a new metric for robotics evaluation. It serves as a critical reminder that in the quest for technological advancement, human values should never be relegated to an afterthought. The challenge is clear: developing robots that aren't just reactive, but also reflective of our most cherished human principles.
