This proposal is to request funding to complete a market study for a novel technology developed in the Robotics Laboratory at Laval University. The technology concerns a novel architecture of robotic platform that allows to move a payload with six degrees of freedom (translations and rotations) with large orientational ranges of motion and using legs that are subjected to only axial loads. Existing platforms have either limited ranges of orientational motion (for example plus or minus 45 degrees in tilt) or make use of architectures that induce bending in the actuating legs, which precludes applications with very large payloads. The potential areas of application of the proposed technology include (but are not limited to): 1) vehicle motion simulation, 2) entertainment motion systems and 3) robotics. Fully parallel flight simulators could greatly benefit from large ranges of orientation provided by the proposed technology, for example in military simulators, where the flight conditions are much more demanding than for commercial aircraft. Also, terrestrial vehicle simulators (e.g. automotive simulators), which require large lateral accelerations, could greatly benefit from the proposed technology by exploiting the rotational capabilities to emulate the lateral accelerations. Entertainment systems, with high dynamic ranges and large throughput (users/hour) constitute a promising application of the proposed architecture of mechanisms. In the area of robotics and machine tools, parallel robots with 6 degrees of freedom are not very common because of their rather limited orientational workspace. Because it can provide large orientational workspace, the proposed technology has the potential to greatly extend the range of applications of parallel mechanisms in industry. The above fields of application and others will be investigated in the proposed market study in order to better understand the commercial potential of the proposed technology and to advise on the relevance of its further development, for example through an I2I Phase I project.

该建议是要求资金完成一项在拉瓦尔大学（Laval University）机器人实验室开发的新技术的市场研究。该技术涉及机器人平台的新型架构，该架构允许以六个自由度（翻译和旋转）的有效载荷，具有大型运动范围，并使用仅承受轴向载荷的腿。现有平台要么具有有限的定向运动范围（例如，倾斜度为45度或减去45度），要么利用诱导弯曲腿弯曲的架构，这排除了具有很大有效载荷的应用程序。拟议技术的潜在应用领域包括（但不限于）：1）车辆运动模拟，2）娱乐运动系统和3）机器人技术。完全平行的飞行模拟器可以从拟议技术提供的大量方向中受益匪浅，例如在军事模拟器中，飞行条件的要求比商用飞机的要求要高得多。此外，需要大型侧向加速的陆地车辆模拟器（例如汽车模拟器）可以通过利用旋转能力来模仿侧向加速度来从提出的技术中受益匪浅。具有高动态范围和大量吞吐量（用户/小时）的娱乐系统构成了提议的机制体系结构的有希望的应用。在机器人技术和机床的领域中，具有6个自由度的平行机器人由于其定向工作空间而不是很常见。由于它可以提供大型的定向工作空间，因此提出的技术有可能大大扩展并行机制在行业中的应用范围。上述应用领域和其他领域将在拟议的市场研究中进行调查，以便更好地了解拟议技术的商业潜力，并建议有关其进一步发展的相关性，例如通过I2I阶段I阶段项目。
