Embodied Agents#

Philosophical Bits#

We believe the essence of intelligence emerges from its dynamic interactions with the external environment, where the use of various tools becomes a pivotal factor in its development and manifestation.

The EmbodiedAgent() in CAMEL is an advanced conversational agent that leverages code interpreters and tool agents (e.g., HuggingFaceToolAgent()) to execute diverse tasks efficiently. This agent represents a blend of advanced programming and AI capabilities, and is able to interact and respond within a dynamic environment.

Quick Start#

🕹 Step 0: Prepartions#

from camel.agents import EmbodiedAgent
from camel.generators import SystemMessageGenerator as sys_msg_gen
from camel.messages import BaseMessage as bm
from camel.types import RoleType

🕹 Step 1: Define the Role#

We first need to set up the necessary information.

# Set the role name and the task
role = 'Programmer'
task = 'Writing and executing codes.'

# Create the meta_dict and the role_tuple
meta_dict = dict(role=role, task=task)
role_tuple = (role, RoleType.EMBODIMENT)

The meta_dict and role_type will be used to generate the system message.

# Generate the system message based on this
sys_msg = sys_msg_gen().from_dict(meta_dict=meta_dict,
                                  role_tuple=role_tuple)

🕹 Step 2: Initialize the Agent 🐫#

Based on the system message, we are ready to initialize our embodied agent.

# Feed the system message to the agent
embodied_agent = EmbodiedAgent(system_message=sys_msg,
                               tool_agents=None,
                               code_interpreter=None,
                               verbose=True)

Be aware that the default argument values for tool_agents and code_interpreter are None, and the underlying code interpreter is using the SubProcessInterpreter(), which handles the execution of code in Python and Bash within a subprocess.

🕹 Step 3: Interact with the Agent with `.step()`#

Use the base message wrapper to generate the user message.

usr_msg = bm.make_user_message(
    role_name='user',
    content=('1. write a bash script to install numpy. '
             '2. then write a python script to compute '
             'the dot product of [8, 9] and [5, 4], '
             'and print the result. '
             '3. then write a script to search for '
             'the weather at london with wttr.in/london.'))

And feed that into your agents:

response = embodied_agent.step(usr_msg)

Under the hood, the agent will perform multiple actions within its action space in the OS to fulfill the user request. It will compose code to implement the action – no worries, it will ask for your permission before execution.

Ideally you should get the output similar to this, if you allow the agent to perform actions:

print(response.msg.content)

>>> Executing code block 0: {Requirement already satisfied: numpy in ...}
>>> Executing code block 1: {76}
>>> Executing code block 2: {
>>> Weather report: london
>>>
>>>       \   /     Sunny
>>>        .-.      +4(1) °C
>>>     ― (   ) ―   ↘ 30 km/h
>>>        `-’      10 km
>>>       /   \     0.0 mm
>>> }

Let’s celebrate the sunny day in London with the agent! : )
