Assistance for Parcel Loading, Unloading, and Retrieval in Delivery Vehicles

AI Quick Summary

Loading, unloading, and retrieving parcels inside vehicles is a physically demanding and critical task in parcel logistics. Workers have to handle parcels of different sizes, weights, and shapes efficiently and in confined spaces, while also organising loads so that items remain accessible, safe, and efficient to retrieve. This creates physical strain, repeated handling, search effort, and productivity losses. The proposed solution is a robotic parcel-handling assistance in delivery vehicles. Using 3D vehicle modelling, simulation, optimisation methods, and AI-based control, the project will evaluate how robotic or semi-automated systems could support parcel loading, unloading, and retrieval under realistic conditions. The project will develop a robotic control system and help identify which robotic assistance concepts are most promising, where they create operational value, and how they could reduce physical strain, improve productivity, and support more consistent and scalable parcel-handling processes. Problem Context Loading and unloading parcels remains one of the most physically demanding and operationally important tasks in delivery logistics. In parcel operations, workers repeatedly handle items of different sizes, weights, and shapes under time pressure and within confined vehicle spaces. This process is labour-intensive, repetitive, and ergonomically challenging, particularly in high-volume delivery rounds where speed, accuracy, and efficient organisation are essential. Loading and unloading is not only a physical task, but also a continuous process of spatial organisation and operational decision-making under constraint. Parcels must be arranged so that subsequent deliveries are efficient, safe, and accessible. Poor load organisation increases search time, creates unnecessary movements, and often requires parcels to be handled multiple times before the correct item can be retrieved. Fragile, bulky, or irregularly shaped items add further complexity. Performance hinges on worker experience, manual skill, and the ability to balance speed with order and safety. These frictions reduce productivity, increase physical strain, and make operations harder to scale consistently across workers and routes. This challenge is becoming more relevant as parcel volumes continue to grow while the sector is also under pressure to improve working conditions, respond to labour shortages, and increase the attractiveness of physically demanding operational roles. For logistics providers, this creates an opportunity to explore whether robotic or semi-automated parcel handling can improve vehicle loading, unloading, and parcel retrieval in a way that is operationally realistic, technically feasible, and compatible with existing delivery processes. The solution The project will develop and evaluate a simulation-based concept for robotic parcel-handling assistance in delivery vehicles. In a first step, we will analyse current loading, unloading, and in-vehicle parcel-retrieval operations in order to understand how parcels are handled, organised, searched for, and retrieved in practice. We will also collect measurements, images, or scans of the truck interior in order to create an accurate 3D model of the vehicle environment. Particular attention will be given to spatial constraints, parcel variability, and parcel accessibility. Based on this understanding, we will build a simulation framework representing the interior of a delivery vehicle and the main parcel-handling tasks. This environment will allow us to evaluate different robotic or semi-automated assistance concepts under realistic conditions. Candidate concepts may include robotic arms or other parcel-handling mechanisms adapted to confined vehicle spaces. Within this framework, we will compare different handling strategies depending on parcel characteristics such as size, weight, shape, fragility, and delivery sequence. The aim is to assess how robotic systems could support parcel loading, parcel retrieval for upcoming stops, and unloading operations. And evaluate the time gained compared to manual operation. The project will test key design choices, including: how parcels should be scanned, identified, and organised inside the vehicle; which robotic handling principles are best suited to mixed parcel flows; how parcel placement can be optimised for both space efficiency and later accessibility; and under which operational conditions robotic assistance creates the greatest value. The work will rely on a combination of 3D vehicle modelling, parcel-handling simulation, optimisation methods for parcel organisation and retrieval, and AI-based control of the robotic system. The study will use representative parcel data, including parcel dimensions, weight, shape, and destination sequence, in order to reflect realistic delivery conditions. Simulation platforms such as NVIDIA Isaac Lab, Isaac Sim, and Omniverse will provide a suitable environment for modelling the truck interior, simulating robot–parcel interactions, and developing and testing AI control strategies for robotic handling under realistic geometric constraints. The project will therefore focus on simulation-based feasibility assessment, concept comparison, operational evaluation, and the development of an AI control model for robotic parcel handling. The objective is to identify the most promising robotic assistance concepts, assess their value and constraints, and lay the groundwork for a future prototyping phase in which the control model could be further adapted to real-world deployment.

Problem Context

Loading and unloading parcels remains one of the most physically demanding and operationally important tasks in delivery logistics. In parcel operations, workers repeatedly handle items of different sizes, weights, and shapes under time pressure and within confined vehicle spaces. This process is labour-intensive, repetitive, and ergonomically challenging, particularly in high-volume delivery rounds where speed, accuracy, and efficient organisation are essential.

Loading and unloading is not only a physical task, but also a continuous process of spatial organisation and operational decision-making under constraint. Parcels must be arranged so that subsequent deliveries are efficient, safe, and accessible. Poor load organisation increases search time, creates unnecessary movements, and often requires parcels to be handled multiple times before the correct item can be retrieved. Fragile, bulky, or irregularly shaped items add further complexity. Performance hinges on worker experience, manual skill, and the ability to balance speed with order and safety. These frictions reduce productivity, increase physical strain, and make operations harder to scale consistently across workers and routes.

This challenge is becoming more relevant as parcel volumes continue to grow while the sector is also under pressure to improve working conditions, respond to labour shortages, and increase the attractiveness of physically demanding operational roles. For logistics providers, this creates an opportunity to explore whether robotic or semi-automated parcel handling can improve vehicle loading, unloading, and parcel retrieval in a way that is operationally realistic, technically feasible, and compatible with existing delivery processes.

The solution

The project will develop and evaluate a simulation-based concept for robotic parcel-handling assistance in delivery vehicles.

In a first step, we will analyse current loading, unloading, and in-vehicle parcel-retrieval operations in order to understand how parcels are handled, organised, searched for, and retrieved in practice. We will also collect measurements, images, or scans of the truck interior in order to create an accurate 3D model of the vehicle environment. Particular attention will be given to spatial constraints, parcel variability, and parcel accessibility.

Based on this understanding, we will build a simulation framework representing the interior of a delivery vehicle and the main parcel-handling tasks. This environment will allow us to evaluate different robotic or semi-automated assistance concepts under realistic conditions. Candidate concepts may include robotic arms or other parcel-handling mechanisms adapted to confined vehicle spaces.

Within this framework, we will compare different handling strategies depending on parcel characteristics such as size, weight, shape, fragility, and delivery sequence. The aim is to assess how robotic systems could support parcel loading, parcel retrieval for upcoming stops, and unloading operations. And evaluate the time gained compared to manual operation.

The project will test key design choices, including:

how parcels should be scanned, identified, and organised inside the vehicle;
which robotic handling principles are best suited to mixed parcel flows;
how parcel placement can be optimised for both space efficiency and later accessibility;
and under which operational conditions robotic assistance creates the greatest value.

The work will rely on a combination of 3D vehicle modelling, parcel-handling simulation, optimisation methods for parcel organisation and retrieval, and AI-based control of the robotic system. The study will use representative parcel data, including parcel dimensions, weight, shape, and destination sequence, in order to reflect realistic delivery conditions. Simulation platforms such as NVIDIA Isaac Lab, Isaac Sim, and Omniverse will provide a suitable environment for modelling the truck interior, simulating robot–parcel interactions, and developing and testing AI control strategies for robotic handling under realistic geometric constraints.
