Thesis Energy Efficient Optimization of Lifting Operations

Movu Robotics
Innovation, ambitious growth, technology, state-of-the-art robots – that’s Movu Robotics in a nutshell. Due to the in-house design and manufacturing process of our systems, an exciting, hands-on work environment with plenty of challenges and advancement opportunities is guaranteed. Will you help shape the future of intralogistics?

Background and Motivation

Lifting operations in automated systems are often energy-intensive and contribute significantly to overall power consumption and cycle time. In many existing implementations, the lifting motor is driven at or near full speed with limited motion shaping.

This can result in high mechanical shock loads when engaging or lifting a payload, leading to increased mechanical stress on the motor, transmission components, and structural elements.

With increasing demands for sustainability, performance, and system durability, optimizing lifting behavior at the software and control level has become increasingly important. Improved motion planning can not only reduce energy consumption and cycle time, but also decrease peak forces, mechanical impact, and wear, thereby potentially extending hardware lifetime and reducing maintenance requirements.

Problem Statement

Existing lifting strategies may lead to unnecessary energy consumption, longer cycle times, and elevated mechanical stress due to aggressive movements. These dynamic loads can negatively impact component lifetime and system reliability.

Methodology

The work will involve modeling the lifting system, including motor characteristics and constraints. Optimization techniques will be applied to generate energy-e icient motion profiles.

The proposed approaches will be evaluated through simulation and/or experimental measurements, comparing energy usage, peak power, cycle time and mechanical impact.

Expected Outcomes

 Optimized lifting and motion profiles

 Quantitative reduction in energy consumption and/or cycle time

 Reduced peak mechanical loads and smoother load engagement  Evaluation of concurrency strategies and their impact on system performance

Scope

The thesis focuses on control and motion planning strategies and does not include mechanical redesign or motor hardware changes.

Addition to Expected Outcomes (Optional)

If implemented, the thesis may additionally deliver: Investigation and implementation of load weight estimation method
