The research being carried out in the department of Cognitive Robotics is being funded by several national and international bodies. The researchers are working on a range of projects including machine learning, neuroscience, animal behaviour, interactive skill learning, and neurobiology. In addition to their research, they have received grants from the NWO and the European Research Council. In addition to their funding, the team has received several awards from the European Research Council.
Machine learning

In late 2014, MIT researchers created an algorithm to make robots learn by doing. The robots learned by exploring a building and processing small pieces of data. Then, using this data to build a knowledge base, they learned to stay upright and move along a moving platform. These new algorithms are being used to develop more effective robots. Several robotic applications are likely to benefit from the technology. But before you build an autonomous robot, you should understand how cognitive robotics works.

Cognitive robotics researchers have been working on using symbolic processing architectures to develop robotic systems that can mimic human and operator performance. The idea is to extend such models to handle real-world sensory input. Sensory input must be translated into a set of symbols that represent the world and its relationships. That means cognitive robotics modelers will have to learn how to interpret the raw data for the robots. They will then have to develop a machine learning framework to train the robotic systems.

To train a robot, it is essential to build a diverse set of skills. These skills should allow the robot to find the optimal path to its goals. The robot will have to be able to generate paths when unplanned situations and errors occur. In addition, the robot needs to learn new skills through intuitive programming and demonstration. This is accomplished by reinforcement learning, which allows the robot to improve on its skills over time. These new skills are referred to as “interactive skill learning.”

As a result, advanced learning of abstract concepts requires a robot body. This is possible through simulation. These pioneering studies have provided information on how artificial learning simulations work. This approach has been demonstrated to be useful in several fields, including neuroscience and psychology. However, these advances are still in their infancy. Further research is needed to develop the technology. The potential of cognitive robotics is limitless. Its potential for enhancing human performance is unmatched.
Neuroscience

Cognitive Neuroscience Robotics is a relatively new interdisciplinary field focused on how human minds work. Comprised of two volumes, Synthetic Approaches to Human Understanding describes advances in the study of neuroscience and robotics while Analytic Approaches focuses on subjects of cognitive science and neuroscience. These two volumes complement each other and explore how artificial systems may acquire intelligent behaviors. The goal of the field is to understand how the brain works and how it can be used to design intelligent machines that are capable of performing complex tasks.

The basic assumptions in cognitive neuroscience vary from branch to branch, but all three theories have some commonalities. They depend on certain basic assumptions. Molecular neurobiology is based on the assumption that the mind is a collection of biologically-inspired molecules and ions, and that they interact with each other to produce emergent mental properties. Other theories focus on the relationship between physical and mental states, such as representational computation, or biologically-inspired models.

The multidisciplinary nature of the group allows it to exploit both hardware and software emulations for cognitive robotics. The group has links to EU, Research Council, and industrial funding sources. Current projects include sensory perception modelling, machine learning and deep learning, and risk identification in robotics. The group also hosts a research forum that brings together experts from various disciplines. Its projects include bridging the gaps between neuroscience and cognitive robotics, and advancing the field.

To improve cognitive robots, researchers should remove them from screens. These robots will have to be placed in situations where they interact with other human beings. This will allow researchers to study the brain activity of robots in their daily lives and use real-world scenarios in order to better understand how human brains process social interaction. The brain regions that are relevant for social interaction include the frontal cortex and superior temporal sulcus.
Animal behaviour

The field of cognitive robotics can use different methodologies to develop its algorithms. Some rely on classical symbolic AI methods that focus on symbolic reasoning, while others incorporate animal behaviour and neuroscience into their research. Here, I will outline the three main approaches in the field of cognitive robotics. All of these methods have their merits. Listed below are some of the more relevant areas of research for cognitive robotics. Read on to discover how these methods might benefit your research.

First of all, we should define the term “behaviour” as a set of characteristics common to all animals. The basic behavior of an animal can be represented mathematically by a model. These models are based on certain assumptions, which specify the animal’s behavior and make it easier to understand. These models can be used to test animal behaviour hypotheses, and many examples are provided. But how do we use them to improve robotic systems?

Many animals display instinctive behavior in response to internal biological rhythms. One such cycle is the 24-hour day/night cycle. Many animals are active during the day, while sleeping at night. This pattern of activity is known as a circadian rhythm, and most animals exhibit close to it. The 24-hour cycle of animal behaviour has been replicated in laboratory settings. And although these results are promising, they are often not sufficient to make robots intelligent enough to function on their own.

In the meantime, robotics researchers are increasingly working on the development of robots that can mimic specific animal systems. These robots will help test hypotheses on how to control animal behaviour. With the help of learning algorithms, researchers can test the effectiveness of specific dendritic circuits and other methods. They will also give insight into the nature of the problem and how best to approach it. For now, it is difficult to develop an effective controller for cognitive robotics.
Interactive skill learning

A central goal of adaptive skill learning in cognitive robotics is to make the robot perform a specific task with limited resources. This process relies on multiple choices from the learner and the teacher, such as data collection methods, representations, inference biases, and learning structure. These choices create an ordered learning trajectory. The type of learning trajectory used affects the learning efficiency. This article will describe a novel approach to adaptive skill learning in cognitive robotics.

An interactive skill learning approach to the development of cognitive robots consists of two strategies: problem-focused and solution-focused. The former involves dividing work among group members. The students involved in cooperative or collaborative activities discussed problem-solving strategies and evaluated robot performance. The collaborative approach was adopted by all students. However, in the case of problem-focused learning, the participants used a Problem-focused strategy. The latter approach involved analyzing scientific papers and online resources for information on cognitive robotics.

A novel approach to skill learning uses autonomous play. This approach involves mapping user commands to skill clips, which represent different robot skills. When the user commands are received, the skill clips are excited and the robot begins the execution process of that skill. In addition to skill execution, there are clips for sensing behaviors. Throughout the exploration process, the robot also develops a set of preparatory behaviors for a given task.

While existing robots are capable of performing repetitive tasks, their performance is constrained by the complexities of the task and the environment. To overcome these constraints, robots should be able to learn by demonstration. While large sensory and joint state information are valuable for learning, they are difficult to apply for demonstration policy. In such cases, a learning-by-imitation approach can be applied. Learning-by-imitation learns from what-where-how interaction data. Learning by imitation is not only effective, but it also allows the robot to generalize to tasks of similar complexity.
Motor babbling

In cognitive robotics, the use of motor babbling is a way to train robots to perform a task. Robots learn body dynamics through a sequence of active and passive motions. These motions are then generalized to untrained situations. This method reduces the number of training iterations for a robot. Motor babbling in cognitive robotics is an interesting technique for a wide range of robot tasks, including tasked navigation.

The successful learning rate of a motor babbling-taught neural network was calculated for different learning scenarios. While a network training without babbling could achieve the task successfully, it was less able to learn novel tasks. The bar graph below shows the number of successful training iterations. By using active-passive motor babbling, the number of training iterations was reduced by 51.5%. This difference was confirmed by t-tests.

When compared with a human, motor babbling is effective at generating exploratory motions. It can perform tasks with many degrees of freedom (DOFs). In a few trials, motor babbling was able to generate motion in untrained situations and for online-motion generation. This process can be further refined through additional learning. Its success rate isn’t high, but it’s definitely higher than passive motion alone.

Achieving dynamic motion tasks using flexible-joint robots has its benefits. Because flexible-joint robots can exploit intrinsic dynamics, they are able to passively adapt to their environment. The proposed methodology uses a two-phase learning framework based on a recurrent neural network and a motor babbling technique. Then, it fine-tunes the motor babbling-trained robot to execute the targeted tasks.
