Model Gemini Robotics ER dapat merencanakan tugas dan melakukan penalaran tentang ruang dengan menyimpulkan tindakan yang harus dilakukan dan objek yang harus dipindahkan untuk menyelesaikan sasaran. Halaman ini menunjukkan contoh untuk melakukan operasi ambil dan letakkan melalui API robot kustom untuk mengatur tugas meletakkan item ke dalam mangkuk. Contoh ini menggunakan model Gemini ER 2 standar. Untuk contoh streaming, lihat Panduan Streaming Gemini ER 2.
Untuk kode yang dapat dijalankan sepenuhnya, lihat Robotics cookbook.
Menggunakan API robot kustom
Contoh ini menunjukkan orkestrasi tugas dengan API robot kustom. API ini memperkenalkan API tiruan yang dirancang untuk operasi ambil dan letakkan. Tugasnya adalah mengambil balok biru dan meletakkannya di mangkuk oranye:

Contoh ini menggunakan mock robot API berikut:
Python
def move(x, y, high):
print(f"Mock Robot: Moving to coordinates: {x}, {y}, {'high above table' if high else 'down at table level'}")
def setGripperState(opened):
print(f"Mock Robot: {'Opening gripper' if opened else 'Closing gripper'}")
robot_origin_y = 300
robot_origin_x = 500
move_function = {
"type": "function",
"name": "move",
"description": "Moves the arm to the given coordinates.",
"parameters": {
"type": "object",
"properties": {
"x": {"type": "integer", "description": "X coordinate relative to the origin"},
"y": {"type": "integer", "description": "Y coordinate relative to the origin"},
"high": {"type": "boolean", "description": "Set to True to lift the robot arm above the scene for avoiding obstacles. Set to False to place the gripper on the surface."}
},
"required": ["x", "y", "high"]
}
}
set_gripper_state_function = {
"type": "function",
"name": "setGripperState",
"description": "Opens or closes the robot's gripper.",
"parameters": {
"type": "object",
"properties": {
"opened": {"type": "boolean", "description": "True opens the gripper, False closes the gripper."}
},
"required": ["opened"]
}
}
Contoh berikut mengirimkan perintah dan gambar ke model dengan definisi alat. Kemudian, loop agentik dijalankan: setelah setiap respons model, fungsi yang diminta (move, setGripperState) akan dieksekusi, hasilnya akan dikembalikan ke model menggunakan previous_interaction_id, dan proses ini akan diulangi hingga model berhenti memanggil fungsi atau batas langkah tercapai.
Python
prompt = (
"You are a robotic arm with six degrees-of-freedom. "
f"The origin point for calculating the moves is at normalized point y={robot_origin_y}, x={robot_origin_x}. "
"Use this as the new (0,0) for calculating moves, allowing x and y to be negative.\n\n"
"Find the blue block and the orange bowl. Calculate their coordinates relative to the origin.\n"
"Perform a pick and place operation where you pick up the blue block and place it into the orange bowl. "
"Call the appropriate sequence of functions to complete this operation."
)
# 1. Initial Interaction
interaction = client.interactions.create(
model=MODEL_ID,
input=[{"type": "user_input", "content": [
{"type": "image", "data": img_b64, "mime_type": "image/png"},
{"type": "text", "text": prompt}
]}],
tools=[move_function, set_gripper_state_function],
generation_config={"thinking_level": "low"}
)
print("\n--- Executing Orchestrated Plan ---")
max_steps = 15 # Safety limit to prevent infinite loops
step_count = 0
# 2. The Agentic Loop
while step_count < max_steps:
step_count += 1
# Check if the model wants to call any functions
tool_calls = [step for step in interaction.steps if step.type == "function_call"]
if not tool_calls:
# If no tools were called, the model is finished with the sequence
print("Sequence complete.")
if interaction.output_text:
print(f"Model Summary: {interaction.output_text}")
break
function_results = []
for step in tool_calls:
function_name = step.name
arguments = step.arguments
# Execute the mock function
if function_name == "move":
move(**arguments)
elif function_name == "setGripperState":
setGripperState(**arguments)
else:
print(f"Unknown function: {function_name}")
# 3. Create a result object to tell the model the function succeeded
function_results.append({
"type": "function_result",
"name": step.name,
"call_id": step.id,
"result": [{"type": "text", "text": '{"status": "success"}'}]
})
# 4. Send the results back to the model, passing previous_interaction_id
# so it remembers the conversation history and generates the NEXT step
interaction = client.interactions.create(
model=MODEL_ID,
previous_interaction_id=interaction.id,
tools=[move_function, set_gripper_state_function],
input=function_results
)
Berikut adalah kemungkinan output model berdasarkan perintah dan API robot tiruan. Outputnya mencakup output panggilan fungsi robot yang diurutkan oleh model.
