RobLog (EU project no. 270350) is an EU-funded collaborative project to create a cognitive and autonomous robot, positioned to answer the arising industry demand for autonomous unloading of containers. The project will result with two fully working physical demonstrators: an Advanced one and an Industrial one at the end of January 2015.

The ingenuity of the RobLog design allows for the unloading of containers that are chaotically packed or that contain heavy and deformable items. A 2008 study revealed that approximately 60% of shipping containers contain goods that fit into three categories: cuboid 41,6%, free-shaped 30,31%, cylindrical 1,45%). Such an autonomous solution, therefore, could produce solid efficiencies and reduce costs in logistics by automating a process that is currently performed by human labor.

RobLog is currently in progress fine tuning the two demonstrators. Both machines will run the same software for object recognition and motion planning, but differentiate in their applications. The Advanced Demonstrator is a flexible system capable of unloading all kinds of goods found in a container. The advanced-object recognition techniques provide for fast detection and grasping of rigid objects known by the system (e.g. boxes and barrels), while on-line grasp planning techniques can be triggered for the grasping of unknown or flexible objects, using a general purpose compliant gripper. The Industrial Demonstrator was especially designed to autonomous and safely unload heavy-sack shaped goods, using coffee sacks (approximately 75 kg) as the objective goal.

An intermediate version of the Industrial Demonstrator was presented at the CeMAT fair, the world‘s leading trade show for intralogistics[*] , that took place May 19 -23, 2014, in Hannover, Germany.

The presence of the RobLog Industrial Demonstrator at such an application-orientated fair was a huge success as this created a direct connection with company representatives who were looking for solutions to implement in the USA, Europe, Asia and the Middle East. Onsite RobLog project members spoke with an array of different principals who meet daily with problems of unloading large, heavy deformable goods such as dirt, sand, flour, sugar and rice. Immediate connections were drawn for potential implementation of such a machine into their facilities, as it could create higher efficiencies by increasing daily output.
