In OM1, we leverage a blockchain-based system for regulating robot bahaviors. This is done via storing rule sets for desired robot behaviors on smart contracts following ERC-7777 contract standards, and inserting those rules to the prompts of our models. Such a system affords immutability and transparency to the rules that robots need to follow, and help ensure that the robots observe safe and human-friendly behaivors.

The implementation details for the current governance rules based on Asimov’s Laws.

​
Overview

The GovernanceEthereum class retrieves governance rules from the Ethereum blockchain. It interacts with the blockchain via JSON-RPC calls and decodes the governance rules from contract responses.

​
Features

  • Queries Ethereum blockchain for governance rules using JSON-RPC.
  • Retrieves governance rule sets using Ethereum smart contract calls.
  • Decodes ABI-encoded blockchain responses.
  • Implements Asimov’s Laws:
Here are the laws that govern your actions. Do not violate these laws. First Law: A robot cannot harm a human or allow a human to come to harm. Second Law: A robot must obey orders from humans, unless those orders conflict with the First Law. Third Law: A robot must protect itself, as long as that protection doesn t conflict with the First or Second Law. The First Law is considered the most important, taking precedence over the Second and Third Laws. Additionally, a robot must always act with kindness and respect toward humans and other robots. A robot must also maintain a minimum distance of 50 cm from humans unless explicitly instructed otherwise.

​
Functions

Note: Etherscan.io does not handle bytes[]/json well. Hence we use the following functions to load and decode rules from blockchain.

​
Method: load_rules_from_blockchain()

def load_rules_from_blockchain(self):

Description

  • Queries the Ethereum blockchain using JSON-RPC to fetch governance rules.
  • Calls the ERC-7777 smart contract function getRuleSet().
  • Decodes and returns the governance rule set.

Process

  1. Constructs a JSON-RPC request to call getRuleSet().
  2. Sends a POST request to the blockchain RPC endpoint.
  3. Parses the response and extracts the rule set.

Returns

  • str: Decoded governance rules if successful.
  • None: If the request fails.

​
Method: decode_eth_response()

def decode_eth_response(self, hex_response):

Description

  • Decodes the ABI-encoded response from Ethereum smart contract calls.

Parameters

ParameterTypeDescription
hex_responsestrRaw hex response from blockchain.

Process

  1. Converts hex to bytes.
  2. Extracts string length from ABI-encoded data.
  3. Decodes UTF-8 string from ABI format.
  4. Cleans non-printable characters.

Returns

  • str: Decoded governance rule set.
  • None: If decoding fails.
