Gaka-chu: a self-employed autonomous robot artist

Abstract: The physical autonomy of robots is well understood both theoretically and practically. By contrast, there is almost no research exploring their potential economic autonomy. In this paper, we present the first economically autonomous robot -- a robot able to produce marketable goods while having full control over the use of its generated income. Gaka-chu ("painter" in Japanese) is a 6-axis robot arm that creates paintings of Japanese characters from an autoselected keyword. By using a blockchain-based smart contract, Gaka-chu can autonomously list a painting it made for sale in an online auction. In this transaction, the robot interacts with the human bidders as a peer not as a tool. Using the blockchain-based smart contract, Gaka-chu can then use its income from selling paintings to replenish its resources by autonomously ordering materials from an online art shop. We built the Gaka-chu prototype with an Ethereum-based smart contract and ran a 6-month long experiment, during which the robot created and sold four paintings, simultaneously using its income to purchase supplies and repay initial investors. In this work, we present the results of the experiments conducted and discuss the implications of economically autonomous robots.

• The paper presents Gaka-chu, an autonomous robot artist that generates paintings from keywords, sells them via blockchain, and uses the income to buy supplies.
• Using blockchain and smart contracts, the system enables the robot to operate as an independent economic agent, managing its own sales and purchases.
• The research suggests that economically independent robots like Gaka-chu could redefine labor and economic roles and be applicable in various fields beyond art.

Overview of "Gaka-chu: a self-employed autonomous robot artist"

The paper "Gaka-chu: a self-employed autonomous robot artist" introduces a novel approach to economically autonomous robotics, exemplified by the development and implementation of Gaka-chu, an artistically inclined robotic system. By employing blockchain technology and smart contracts, Gaka-chu not only generates art but also autonomously manages its financial interactions in the market, thus operating as an independent economic agent.

Key Contributions

The research describes Gaka-chu, a 6-axis robotic arm capable of creating paintings from self-selected keywords, which are popular search terms obtained from Google Trends. These keywords are transformed into Japanese characters and imaged onto a canvas. Subsequently, Gaka-chu autonomously sells these paintings via a blockchain-based auction system and utilizes the income to purchase necessary art supplies and repay initial investors.

Technological Innovations

1. Economic Autonomy: The paper distinguishes itself by actualizing the concept of economic autonomy, enabling a robot to independently engage in the production and sale of goods while overseeing its economic lifecycle. Key transactions are facilitated using Ethereum-based smart contracts, thus minimizing human intervention in the financial process.
2. Integration of Art Creation and Economics: By blending the field of physical, creative output with autonomous economic agency, this work introduces a pioneering method of robotic application within an economic context typically reserved for humans.
3. Blockchain Implementation: The use of blockchain ensures secure and transparent financial transactions, while smart contracts automate the economic activities of Gaka-chu, including sales and inventory replenishment.

Methodology

The implementation involved several technical steps:

• Artistic Process: Using computer vision and image processing techniques, Gaka-chu selects and processes the day's most searched keyword into a visual representation that it paints on canvas.
• Auctioning and Income Management: Paintings are listed for online auction, managed by a smart contract that facilitates the bidding process. Upon sale, Gaka-chu receives cryptocurrency, which it uses to autonomously purchase art materials through a web interface that interacts seamlessly with Ethereum transactions.

Experimental Results

Over a six-month period, Gaka-chu conducted a series of painting productions and successful auctions. The financial transactions included auction revenue and the subsequent purchase of art supplies, demonstrating the robot's ability to sustain its operations financially. The experimental results illustrated the feasibility of the proposed system within real-world constraints.

Implications and Future Directions

The introduction of economically autonomous robots like Gaka-chu holds significant implications for the future of robotics and economic systems:

• Redefining Labor and Economic Roles: As robots take on more economically independent roles, there may be substantial shifts in how labor and value creation are defined, raising questions about property rights, intellectual property, and labor laws.
• Potential for Broad Application: While Gaka-chu is currently limited to the artistic domain, the underlying principles can be generalized to various fields, including manufacturing, logistics, and service industries.
• Future Development: Future work could explore enhancing the sophistication of art style selection, as well as expanding the types of economic transactions and services handled autonomously by robots, such as utility payments or maintenance planning.

In conclusion, Gaka-chu represents a seminal step towards integrating economic independence within robotic systems, suggesting a powerful new direction for the development of robotic agents that not only automate tasks but also participate as active economic entities within society.
