Know Your Terms: a Robotics Glossary

Know Your Terms: a Robotics Glossary

Technology can be a little intimidating at times, but it doesn’t have to be. If you are wondering what robotics and automation can do to improve your warehouse operations, but find yourself getting lost in a maze of buzzwords and acronyms, we’re here to help. 

We’ve compiled a running list that explains what many of the terms related to robotics, automation, and fulfillment mean so you can better understand the benefits of these technologies and make an informed decision about what system is right for you.

3PL

3PL is short for Third-Party Logistics. A 3PL provider is used by an e-commerce business to outsource part or all of its distribution and fulfillment services. One example of a 3PL is Rakuten Super Logistics, which has deployed inVia Robotic’s picking robots across its fulfillment network.

AGV

AGV stands for Automated Guided Vehicle. AGVs are used to transport heavy items such as stacks of pallets, rolls of paper or metal, and auto parts along a defined route in a factory or warehouse. 

AMR

AMR is short for Autonomous Mobile Robot. AMRs use technologies like advanced sensors, computer vision, and machine learning to navigate a warehouse, avoid obstacles and deliver items to a picking station.

AMMR

AMMR stands for Autonomous Mobile Manipulator Robot. It’s the kind of robot we design and build here at inVia. AMMRs combine the autonomy of an AMR with the ability to manipulate goods on a shelf and bring them to the pick station. This significantly cuts down one of the biggest expenses incurred by fulfillment centers: walking time.

AS/RS

AS/RS is short for Automated Storage and Retrieval System. These systems are designed to automatically place and retrieve items from defined storage locations in a warehouse.

Cobot

Cobot is short for Collaborative Robot. A cobot is a robot intended to physically interact with people in a shared workspace. 

Cycle Counting

Cycle counting is a procedure where a small section of warehouse inventory in one area is counted at a specific time to forecast the total amount of inventory of that item.

Degrees of Freedom

A degree of freedom refers to a thing’s ability to move in a single independent direction of motion. Moving forward & backward is one degree, moving right & left is another, and up & down is another.

End Effector

An end effector is a device at the end of a robotic arm, designed to interact with the environment, such as our patented suction picker.

Fiducial

A fiducial (or fiducial marker) is a point of reference. They are part of the system we use in warehouses to ensure inVia's robots locate and retrieve items quickly. They also facilitate our robots' ability to navigate using machine vision, which lets them work completely autonomously.

GTP (or G2P)

GTP stands for Goods to Person. It’s a method of order fulfillment utilizing an automated storage and retrieval system (fixed conveyors or autonomous mobile robots) to deliver SKUs to a pick station. 

Industry 4.0

Industry 4.0 refers to the Fourth Industrial Revolution, which is being driven by technological breakthroughs in fields such as quantum computing, biotechnology, autonomous vehicles, artificial intelligence, and robotics.

LIDAR

LIDAR is short for Light Detection and Ranging. It’s a 3D mapping technology that uses pulses of laser light to measure distances. If you’ve ever seen an autonomous car, it’s that thing on the roof.

Localization

Localization is the process of determining where a mobile robot is located with respect to its environment. It's how robots navigate autonomously throughout a warehouse picking items.

Orders, Lines & Units

-An order is the shopping cart filled with items a customer purchases.

-Lines are the different items within the order.

-Units are the quantity of each line.

Picking

In an e-commerce order fulfillment warehouse, picking is the process of gathering the items in a customer’s order. There are several strategies to maximize efficiency, including batch, wave, and zone picking.

Pick-to-Light

Pick-to-Light is an e-commerce order fulfillment method that uses light modules mounted on shelves or racks to guide pickers to the product locations and quantities needed to fill orders. 

Put Wall

A put wall looks like a large shelf unit that’s divided into slots. Each slot is assigned an order. Pickers retrieve items for the order from the warehouse and put them in the slot. When all the items in the order are in the slot, they’re boxed and shipped.

Replenishment

Replenishment is the process of moving items (SKUs) from storage to picking locations. When inventory falls to minimum pre-defined levels, inVia’s Robotics Management System (RMS) directs automated robots to deliver those totes to the replenishment station. The totes are then refilled, and the robots return them to their places in the picking path.

Returns

Customers return items, and processing those returns can be costly. Return rates for online purchases are around 30%, with clothing returns closer to 40%. inVia's robots can manage the flow of returning products to the warehouse. They carry them back to the right location, and our RMS updates inventory data to ensure all products are accurately accounted for.

RFID

RFID is short for Radio-frequency identification. RFID uses electromagnetic fields to automatically identify and track tags attached to objects, like totes, boxes or individual items in a warehouse, providing real-time updates of inventory. 

ROC

ROC stands for Robotics Operations Center. We staff our ROC at inVia Robotics HQ with a team of robotics technicians to monitor your inVia system 24/7. We identify any potential issues before they become problems and can make adjustments to robots mid-fulfillment to prevent disruptions.

RPA

RPA stands for Robotic Process Automation. RPA has nothing to do with physical robots. Instead, RPA is a way to automate business processes by creating software “robots” to perform the tedious tasks that people get stuck doing instead of spending their time focusing on more meaningful work.

SLAM

SLAM is short for Simultaneous Localization and Mapping. SLAM algorithms allow things like autonomous mobile robots and self-driving cars to map their environment and determine their location within it.

The 3 Ds of Robotics

The 3 Ds of robotics are dull, dirty, and dangerous. Those are the 3 types of jobs that no person wants to do, but they still need to be done.

Traveling Salesman Problem

The Traveling Salesman Problem (TSP) is a classic algorithmic problem in the field of computer science that’s focused on optimization. Solving it could change everything from e-commerce to encryption.

Triage

When a customer’s order is incomplete or contains incorrect or duplicate items, the process of fixing it is known as triage. The triage area is like the ER of a fulfillment warehouse—it’s where orders go to get repaired.

UPH

UPH stands for units per hour and is a standard metric of throughput. An online order is comprised of different items (lines), and the quantity of each item (units). An order of 3 hats and 5 shirts is 2 lines and 8 units.

Visual Servoing

Visual servoing, also known as vision-based robot control, is a technique which uses feedback information extracted from a vision sensor to control the motion of a robot.

WMS

WMS stands for Warehouse Management System. It’s a software application that’s designed to manage the day-to-day operations of a warehouse or distribution center, including receiving inventory, storage, picking, packing, shipping and replenishment.
