Physical AI Example: Warehouse Picking Robot

Here’s a simple but realistic example to make the concepts concrete.
If your hackathon idea can't beat this level of clarity, fix it.

Scenario​

A warehouse robot must:

  1. Navigate to a shelf
  2. Identify the correct item
  3. Pick it up
  4. Deliver it to a packing station

Classic Physical AI task.

How Perception Works Here​

  • Camera detects barcodes and shapes
  • Depth sensor maps shelf distance
  • IMU tracks robot orientation
  • Force sensors ensure the gripper doesn’t crush the item

Without this, the robot grabs the wrong object or slams into shelves like an idiot.

How Planning Works Here​

The robot performs:

Path planning​

  • Uses A* or D Lite* to find shortest collision-free route.

Motion planning​

  • Plans smooth trajectories around boxes and humans.

Task planning​

  • “Go to shelf → Locate item → Pick item → Navigate back.”

How Control Works Here​

  • PID controllers keep wheel speed consistent.
  • Arm control uses inverse kinematics to reach the item accurately.
  • Gripper pressure control prevents item damage.

If this layer is poorly tuned → uncontrolled shaking, dropped items, or total failure.

Embodiment in This Example​

  • Wheeled base for mobility
  • 6-DOF robotic arm for manipulation
  • Parallel gripper for stable grasp
  • Battery pack for long operation
  • Sensor suite mounted at optimal angles

The body enables the tasks — not the other way around.

Why This Example Matters​

It shows the complete Perception–Planning–Control loop in action.
This is the minimum bar for any Physical AI system worth being judged in a hackathon.

If your prototype or concept doesn’t demonstrate at least some version of this loop, then it’s incomplete.
