Agentic xArm Simulation

xarm-perception-sim-agent runs the xArm perception, planning, MuJoCo simulation, MCP server, and built-in agent together. It is simulation-only; This guide uses this blueprint to provide a walk-through of dimos's agentic manipulation stack.

See the manipulation capability overview for the underlying planning and perception stack.

Prerequisites

Install the manipulation dependencies:

uv sync --extra manipulation --inexact

The built-in agent requires an OPENAI_API_KEY.

Start and stop

Run in the foreground:

uv run dimos run xarm-perception-sim-agent

Or run it as a daemon:

uv run dimos run xarm-perception-sim-agent --daemon

Inspect and control the run from another terminal:

uv run dimos status
uv run dimos log
uv run dimos stop

Use dimos log -f to follow the log while the run is active.

Daily interaction

For normal interactive use, start the human-friendly terminal client:

uv run dimos humancli

It connects to the running agent so you can send prompts and read responses in one session.

Try these prompts

Start with a non-motion state check:

Report the current robot state without moving.

Scan the latest camera frame for objects without moving the arm:

Scan for objects.

Try basic motion commands:

Move 10 cm to the left.

Move 10 cm above the detected object's pose.

Debugging and testing interfaces

Use agent-send for one-shot LCM input when testing or diagnosing the agent:

uv run dimos agent-send "Report the current robot state and visible objects; do not move the arm or gripper."

The blueprint also includes an MCP server. Use these commands for direct server inspection and tool-level testing:

uv run dimos mcp status
uv run dimos mcp list-tools

For example:

uv run dimos mcp call get_robot_state
uv run dimos mcp call scan_objects --json-args '{"prompts": ["cup"]}'
