这Open Dynamic Robot Initiative(ODRI) has developed an open-source 3D printed robot that can be controlled remotely over Wi-Fi.
这research project started off as an attempt to build a low-cost, brushless motor-based actuator module that could be used to develop various types of torque-controlled robots. Having now been in the works for around five years, the development platform can be combined with 3D printing, cheap PCBs, and off-the-shelf components to build custom legged robots at a fraction of the cost of波士顿动力学的位置（零售只是$ 74,500）。
ODRI的开发模块已被用来构建一只名为Solo的3D打印机器人狗和一个名为Bolt的AT-S-S-Spired Biped Biped Robot。
What is the Open Dynamic Robot Initiative?
ODRI是由几个与机器人有关的研究机构领导的合作开源项目：运动和对照组， 这Max-Planck Institute for Intelligent Systems，，，，纽约大学的丹顿工程学院，和Laas/CNR。
这work ultimately aims to meet the needs of the robotics research community, where many institutions are seeking a flexible research platform that’s low-cost and lightweight. ODRI’s robot development module can largely be 3D printed and is completely upgradable and modifiable, offering an affordable route to advanced R&D for robotics teams on limited budgets.
According to ODRI, its robot platform can be used to research animal-based limb movement over surfaces such as gravel, soil, sand, and mud, and reinforcement learning for complex behaviors such as parkour. Some of this research would be far too risky to attempt on a high-cost platform. Additionally, it can also be used to research environment manipulation motions such as opening doors or pushing buttons, and integration with advanced communications technologies such as 5G wireless.
将Wi-Fi整合到混合物中
尽管该平台多年来已经走了很长一段路，但最新的创新之一是Wi-Fi连接的整合。该设备的算法闭环控制实际上是在单独的PC上托管的，而不是在板载计算机上。在机器人的主体上可以找到的所有内容是由面向现场的控制驾驶员单元，无线控制器和电池驱动的一些无刷直流电动机。
对于这样的项目，通常是使用腿部单位传感器在本地计算所有定位，扭矩和速度的标准练习。However, calculating the motion planning locally requires considerable local processing power, which makes development more difficult as you’d have to fit a high-power PC into a space that high-power PCs don’t really fit in yet – especially if you intend to program the device to perform complex movements.
With minimal electronics and lightweight 3D printed parts, ODRI managed to get Solo, the robotic dog variant, down to a total mass of just 2.2kg with a standing hip height of approximately 24cm.
Further details of the robot development module can be found in the paper titled ‘An Open Torque-Controlled Modular Robot Architecture for Legged Locomotion Research’. Additionally, the可以在项目GitHub上找到机器人的开源文件。
与此相类似，XRobots’ James Bruton，，，，a robotics engineer and 3D printing YouTuber, recently commenced work on他的3D印刷机器人狗的V3。开源项目被称为opendog，已经运行了几年，除了电动机，轴承和其他一些组件外，还可以完全在低成本的FDM系统上打印出3DLulzBot TAZ WorkhorseBruton happens to use.
在开源社区的其他地方，3D打印YouTuberTeaching Techrecently designed and 3D printed his ownopen-source version of a rare antique fractal vise。Dubbed ‘the coolest tool you didn’t know you needed’, the 100-year-old fractal vise is near impossible to purchase these days, and is capable of morphing to grip virtually any object.
