Autonomous Mobile Platform For Smart Factories & Warehouses

Market Opportunity

Mobile platform such as Automated Guided Vehicle (AGV) are increasingly being used alongside humans in hospitals, warehouses, and factories for assistance as well as object movement.  However, in these environments, which are often congested and filled with constantly moving objects, conventional AGVs have a huge limitation due to the need for complex manoeuvring and motion planning.  When equipped with suitable sensors for localization and navigation, the system can work autonomously without the use of both targeting landmarks (walls, objects, etc.) as well as predefined points (magnetic spot and magnetic tape).
 

Technology

Our autonomous mobile platform adopts a novel omni-directional mobility drive system invented by Prof. Yu Haoyong. Due to its use of conventional wheels, this patented technology has a range of advantages over any other omni-directional mobility platforms, such as a high payload capacity and terrain adaptability.  The loading capacity of the displayed platform can carry more than 200kg and can move on carpeted floors and traverse uneven ground.  Coupled with autonomous technology from NUS & MIT joint lab, the autonomous mobile platform is equipped with Dynamic path planning using optimal Rapidly-exploring Random Tree (RRT*) algorithm. Upon sensing an obstacle along the path, the starting point is a threshold distance away from the obstacle and the goal point is somewhere along the original major path. When the vehicle is obstructed, it will use RRT* to map out the possible paths within a specified radius that includes the goal point.

 

Applications & Advantages

The combination of an omni-directional mobility drive system and the autonomous technology, the autonomous mobile platform can be used in many indoor environments where robots interact and collaborate with humans. In manufacturing facilities, facility staff can work with the autonomous mobile platform, e.g. to load materials, parts or products into containers or shelves mounted on the mobile platform. In Warehouse Management application, staff can use supply chain management software e.g. SAP EWM to update part or material orders so when the loaded mobile platform is sent off, an unloaded unit can respond to the worker to take on a new job. The Autonomous Mobile Platform with omni-directional mobility offer a greater advantage due to their capability to move freely in clustered environments.  
 

Value Proposition

In environments, which are often congested and filled with constantly moving objects, conventional AGVs have a huge limitation due to the need for complex maneuvering and motion planning. The combination of an omni-directional mobility drive system and the unique autonomous technology, the autonomous mobile platform can be used in many indoor environments where robots interact and collaborate with humans in clustered environments. The proposed Autonomous Mobile Platform offer a greater advantage over conventional AGV due to their capability to move freely in clustered environments, collaborate  with human without complex pre-determined motion & factory/warehouse layout planning.
