Special Issue Information

Dear Colleagues,

Multi-robot systems appear to be the next frontier of robotics: they comprise a set of autonomous robots living in a real-world environment that cooperate to achieve a common goal; therefore, during operation, each robot must not only take into account the problems related to its own control, but also, and above all, the fact that the overall goal is split into parts, each one in charge of a specific entity. This characteristic enables the pursuit of novel research related to interaction, cooperation and planning in the presence of a world populated by multiple artificial systems. Since “autonomy” is a contentious word, interaction must consider an exchange of meaningful messages that reflect the “state of mind” (knowledge, goals, plans, intentions, etc.) of each single robot, while cooperation and planning imply considering a state of mind that is spread among all the entities. In addition, the path followed by such robotic systems must consider the fact that robots, while exchanging data, may better optimize their movements by exploiting mutual knowledge. In other words, the technologies used to favor these aspects must deal with problems ranging from communication protocols to the meaningful semantics of the messages exchanged, state of mind representation, reasoning, path planning, goal achievement, etc.

The proposed Special Issue aims to gather novel research in the context described and considers, in particular, the following topics:

  • interaction protocols in multi-robot systems
  • distributed artificial intelligence
  • swarm intelligence
  • planning and reasoning in multi-robot systems
  • collaborative path planning
  • flock organization and formation
  • area coverage
  • application and case-studies of multi-robot systems

I look forward to receiving your contributions.

Robots in hazardous environments demand precise and advanced motion control, making extensive simulations crucial for verifying the safety of motion planning. This paper presents a simulation system that enables interactive path editing, allowing for motion planning in a simulated collaborative robot environment and its real-world application. The system includes a simulation host, a control board, and a robot. Unity 3D on a Windows platform provides the simulation environment, while a virtual Linux environment runs ROS2 for execution. Unity sends edited motion paths to ROS2 using the Unity ROS TCP Connector package. The ROS2 MoveIt framework generates trajectories, which are synchronized back to Unity for simulation and real-world validation. To control the six-axis Indy7 collaborative robot, we used the MIO5272 embedded board as an EtherCAT master. Verified trajectories are sent to the target board, synchronizing the robot with the simulation in position and speed. Data are relayed from the host to the MIO5272 using ROS2 and the Data Distribution Service (DDS) to control the robot via EtherCAT communication. The system enables direct simulation and control of various trajectories for robots in hazardous environments. It represents a major advancement by providing safe and optimized trajectories through efficient motion planning and repeated simulations, offering a clear improvement over traditional time-consuming and error-prone teach pendant methods.

In this study, we present a novel approach to derive hand poses from data input via a haptic controller, leveraging machine learning techniques. The input values received from the haptic controller correspond to the movement of five fingers, each assigned a value between 0.0 and 1.0 based on the applied pressure. The wide array of possible finger movements requires a substantial amount of motion capture data, making manual data integration difficult. This challenge is primary due to the need to process and incorporate large volumes of diverse movement information. To tackle this challenge, our proposed method automates the process by utilizing machine learning algorithms to convert haptic controller inputs into hand poses. This involves training a machine learning model using supervised learning, where hand poses are matched with their corresponding input values, and subsequently utilizing this trained model to generate hand poses in response to user input. In our experiments, we assessed the accuracy of the generated hand poses by analyzing the angles and positions of finger joints. As the quantity of training data increased, the margin of error decreased, resulting in generated poses that closely emulated real-world hand movements. Full article
