ROS support and educational materials for open-source mobile robot

The goal of the project is to develop Robot Operating System (ROS) wrapper functions for drivers of an open-source mobile robot platform, that has been successfully used in Robotex competitions. Additionally, educational materials must be developed to integrate the robot platform into ROS ecosystem. The outcome of this work will give a lot of educational uses and rapid prototyping opportunities for the platform.

Detecting features of urban and off-road surroundings

Accurate navigation of self-driving unmanned robotic platforms requires identification of traversable terrain. A combined analysis of point-cloud data with RGB information of the robot's environment can help autonomous systems make correct decisions. The goal of this work is to develop algorithms for terrain classification.

Robotic simulations (in Gazebo)

1) Developing large area simulation worlds for mobile robotics. In order to develop robot navigation algorithms, it is more time- and cost-efficient to test robot behavior in a wide range of realistically simulated worlds. These simulated worlds include both indoor and outdoor environments. This work focuses on designing robot simulation environments using an open-source platform Gazebo.
2) Humans in Gazebo. Integrating walking and gesturing humans to Gazebo.
3) Tracked Robots in Gazebo. Creating and testing tracked robotis in Gaxebo and testing different track configurations.
4) Robot basketball simulation for game strategy and shot accuracy
5) Robotont at the Institute of Technology

Follow-the-leader robotic demo

Detecting 2 hands with Leap Motion Controller

The idea is to create a robotic demonstration where a mobile robot is using Kinect or similar depth-camera for identifying a person and then starts following that person. The project will be implemented using Robot Operating System (ROS) on either KUKA youbot or similar mobile robot platform.

Detecting hand signals for intuitive human-robot interface

This project involves creating ROS libraries for using either a Leap Motion Controller or an RGB-D camera to detect most common human hand signals (e.g., thumbs up, thumbs down, all clear, pointing into distance, inviting).

Virtual reality user interface (VRUI) for intuitive teleoperation system

Adding virtual reality capability to a gesture- and natural-language-based robot teleoperation system.

3D scanning of industrial objects

Using laser sensors and cameras to create accurate models of inustrial producst for quality control or further processing.

Modeling humans for human-robot interaction

True human-robot collaboration means that the robot must understand the actions, intention, and state of its human partner. This work invovlves using cameras and other human sensors for digitally representing and modelling humans. There are multiple stages for modeling: a) physical models of human kinematics and dynamics; b) higher level-models for recognizing human intent.

ROS wrapper for Estonian Speech Synthesizer

Creating a ROS package that enables robots to speak in Estonian. The basis of the work is the existing Estonian language speech synthesizer that needs to be integrated with ROS sound_play package or a stand-alone ROS wrapper package.

Upgrading KUKA youBot

KUKA youBot is omnidirectionl mobile manipulator platform. The project involves replacing the current onboard computer with a more capable one, installing newer version of Ubuntu Linux and ROS, testing core capabilities, and creating documentation for the robot.

Development of strategies for inter-robot knowledge representation

An inseparable part for making robots work together is to enable them to share knowledge about surrounding environment and robot's intention. This project focuses on developing and testing the methodologies for inter-robot knowledge representation. This project is developed as a subsystem of TeMoto.

TeMoto based smart home control

The project involves designing a open-source ROS+TeMoto based scalable smart home controller.

Detection of hardware and software resources for smart integration of robots

Vast majority of today’s robotic applications rely on hard-coded device and algorithm usage. This project focuses on developing a Resource Snooper software, that can detect addition or removal of resources for the benefit of dynamic reconfiguration of robotic systems. This project is developed as a subsystem of TeMoto.

Sonification of feedback during teleoperation of robots

Humans are used to receiving auditory feedback in their everyday lives. It helps us make decision and be aware of potential dangers. Telerobotic interfaces can deploy the same idea to improve the Situational Awareness and robotic task efficiency. The thesis project involves a study about different sonification solutions and implementation of it in a telerobotic application using ROS.

Human-Robot and Robot-Robot collaboration applications

Creating a demo or analysis of software capabilities related to human-robot or tobot-robot teams

• human-robot collaborative assembly
• distributed mapping; analysis and demo of existing ROS (e.g., segmap https://youtu.be/JJhEkIA1xSE) packages for multi-robot mapping
• Inaccessible region teamwork
  • youbot+drone - a drone maps the environment (for example a maze) and ground vehicle uses this information to traverse the maze
  • youbot+clearbot - youbot cannot go up ledges but it can lift smaller robot, such as clearbot, up a ledge.

The goal for this project is to develop ROS drivers for LEHF32K2-64 gripper. The work is concluded by demonstrating the functionalities of the gripper via pick-and-place task.

Mirroring human hand movements on industrial robots

Making KUKA youBot user friendly again

This thesis focuses on integrating the low-level software capabilities of KUKA youBot in order to achieve high-level commonly used functionalities such as

• teach mode - robot can replicate user demonstrated trajectories
• end-effector jogging
• gripper control
• gamepad integration - user can control the robot via gamepad
• web integration - user can control the robot via internet browser

The thesis is suitable for both, master and bachelor levels, as the associated code can be scaled up to generic "user-friendly control" package.

Flexible peer-to-peer network infrastructure for environments with restricted signal coverage

A very common issue with robotics in real world environments is that the network coverage is highly dependent on the environment. This makes the communication between the robot-to-base-station or robot-to-robot unreliable, potentially compromising the whole mission. This thesis focuses on implementing a peer-to-peer based network system on mobile robot platforms, where the platforms extend the network coverage between, e.g., an operator and a Worker robot. The work will be demonstrated in a real world setting, where common networking strategies for teleoperation (tethered or single router based) do not work.
