CSA Exploration Core 2009 Concept Studies: an Overview CSA Exploration Core 2009 Concept Studies: An Overview Eric Martin, Jean-Claude Piedbœuf Space Exploration, Canadian Space Agency 6767 Route de l'Aéroport, St-Hubert, Québec, Canada, J3Y 8Y9 e-mail: [email protected], [email protected] Abstract In 2009, the CSA awarded nine contracts for Space Within the Exploration Core context, the Canadian Exploration Concept Studies that could lead to the Space Agency (CSA) has awarded nine contracts in 2009 creation, approval and implementation of potential to conduct advanced concept studies. These studies focus Canadian space exploration activities. These studies on the identification of the technological and scientific focus on the identification of the technological and needs and on the mission analysis. As the initial phase in scientific needs and on the mission analysis. From the payload/mission development, it provides an opportunity nine studies, six were related to technology development for exploring truly innovative ideas. From the nine in the field of robotics while three studies were about the studies, six were related to technology development development of scientific instruments to achieve specific related to the field of robotics while three studies were science objectives. The key objectives of each of these about the development of scientific instruments to studies are described in the following sections. For each achieve specific science objectives. A description of study, an overview of the proposed concept to meet the the main objectives and the work accomplished in each mission requirements is presented. It is important to note of the six studies related to the robotics field is provided that these concepts represent the main results of the in this paper. studies.

  • Kinematic Modeling of a Rhex-Type Robot Using a Neural Network
    Kinematic Modeling of a RHex-type Robot Using a Neural Network Mario Harpera, James Paceb, Nikhil Guptab, Camilo Ordonezb, and Emmanuel G. Collins, Jr.b aDepartment of Scientific Computing, Florida State University, Tallahassee, FL, USA bDepartment of Mechanical Engineering, Florida A&M - Florida State University, College of Engineering, Tallahassee, FL, USA ABSTRACT Motion planning for legged machines such as RHex-type robots is far less developed than motion planning for wheeled vehicles. One of the main reasons for this is the lack of kinematic and dynamic models for such platforms. Physics based models are difficult to develop for legged robots due to the difficulty of modeling the robot-terrain interaction and their overall complexity. This paper presents a data driven approach in developing a kinematic model for the X-RHex Lite (XRL) platform. The methodology utilizes a feed-forward neural network to relate gait parameters to vehicle velocities. Keywords: Legged Robots, Kinematic Modeling, Neural Network 1. INTRODUCTION The motion of a legged vehicle is governed by the gait it uses to move. Stable gaits can provide significantly different speeds and types of motion. The goal of this paper is to use a neural network to relate the parameters that define the gait an X-RHex Lite (XRL) robot uses to move to angular, forward and lateral velocities. This is a critical step in developing a motion planner for a legged robot. The approach taken in this paper is very similar to approaches taken to learn forward predictive models for skid-steered robots. For example, this approach was used to learn a forward predictive model for the Crusher UGV (Unmanned Ground Vehicle).1 RHex-type robot may be viewed as a special case of skid-steered vehicle as their rotating C-legs are always pointed in the same direction.

Salami, Adegoke A. S., Adesanya G. E., Obadare Bolatito J Abstract— This paper proposes an improved benefits of integration of Unmanned Aerial vehicle (UAV) and Portable Magnetic Resonance Imaging (PMRI) system in relation to developing Precision Agricultural (PA) that is capable of carrying out a dynamic internal quality assessment of crop developmental stages during pre-harvest period. A comprehensive review was carried out on application of UAV technology to Precision Agriculture (PA) progress and evolving research work on developing a Portable MRI system. The disadvantages of using traditional way of obtaining Precision Agricultural (PA) were shown. Proposed Model Architecture of Coupled Unmanned Aerial vehicle (UAV) and Portable Magnetic Resonance Imaging (PMRI) System were developed and the advantages of the proposed system were displayed. It is predicted that the proposed method can be useful for Precision Agriculture (PA) which will reduce the cost implication of Pre-harvest processing of farm produce based on non-destructive technique.

Received in revised form: August 31th, 2015. Accepted: September 9th, 2015 Abstract This paper reports on the design of an open source-based control platform for the underwater remotely operated vehicle (ROV) Visor3. The vehicle’s original closed source-based control platform is first described. Due to the limitations of the previous infrastructure, modularity and flexibility are identified as the main guidelines for the proposed design. This new design includes hardware, firmware, software, and control architectures. Open-source hardware and software platforms are used for the development of the new system’s architecture, with support from the literature and the extensive experience acquired with the development of robotic exploration systems. This modular approach results in several frameworks that facilitate the functional expansion of the whole solution, the simplification of fault diagnosis and repair processes, and the reduction of development time, to mention a few. Keywords: open-source hardware; ROV control platforms; underwater exploration.

  • An Open-Source Watertight Unmanned Aerial Vehicle for Water Quality Monitoring
    An Open-Source Watertight Unmanned Aerial Vehicle for Water Quality Monitoring Paulo Rodrigues, Francisco Marques, Eduardo Pinto, Ricardo Pombeiro, Andre´ Lourenc¸o, Ricardo Mendonc¸a, Pedro Santana, and Jose´ Barata Abstract—This paper presents an open-source watertight mul- tirotor Unmanned Aerial Vehicle (UAV) capable of vertical take- off and landing on both solid terrain and water for environmental monitoring. The UAV’s propulsion system has been designed so as to also enable the active control of the UAV’s drift along the water surface. This low power locomotion method, novel to such a vehicle, aims to extend the available operation time on water bodies’ surveys. The ability to take-off from water allows the UAV to overcome any obstruction that appears on its path, such as a dam. A set of field trials show the UAV’s water-tightness, its take-off and landing capabilities in both land and water, and also the ability to actively control its on-surface drifting. I. INTRODUCTION Current techniques for water monitoring rely on manned teams [1], on remote information, such as the one provided by Fig. 1. The proposed UAV prototype taking-off from the water surface. satellites [2], [3], or on the deployment of Unmanned Surface Vehicles (USV) [4], [5], [6], [7]. The remoteness, and vastness of water bodies render the use of manned teams expensive and of amphibious vehicles that could autonomously navigate on dangerous. Remote sensing offers an alternative but the data land so as to reach the next water body’s segment. Although gets too often outdated, a fact that, added to its inadequacy amphibious robots are already available [8], [9], the ability to retrieve samples, significantly limits its applicability.
