The Bogus Finger is a remote-controllable tool for simulating vertical pressing forces of various magnitude as exerted by a human finger. Its main application is the characterization of haptic devices under realistic active touch conditions. The device is released as an open-source hardware and software DIY project that can be easily built using off-the-shelf components. We report the characterization of the quasi-static properties of the device, and validate its dynamic response to pressing on a vibrating surface by comparison with human fingers. The present prototype configuration accurately reproduces the mechanical impedance of the human finger in the frequency range 200-400 Hz.

用于模拟静态和振动表面上的准静态手指按压的开源机器人工具


Bogus Finger 是一种远程控制工具，用于模拟人类手指施加的各种大小的垂直压力。其主要应用是在真实主动触摸条件下表征触觉设备。该设备作为开源硬件和软件 DIY 项目发布，可以使用现成的组件轻松构建。我们报告了该设备的准静态特性的表征，并通过与人类手指进行比较来验证其对按压振动表面的动态响应。目前的原型配置准确地再现了人类手指在 200-400 Hz 频率范围内的机械阻抗。
