AI 中文总结

TacGELLO利用3D打印主端设备的现有伺服电机和AnySkin接触检测,提供触觉反馈与电流负载提示,显著降低遥操作抓取中的指令闭合误差,提升接触感知精度。

AI 中文摘要

被动式主端机械臂在传递操作者运动时,无法返回远程接触或负载提示。TacGELLO利用3D打印主端设备现有的伺服电机,在夹爪扳机处提供触觉接触反馈,并在机械臂关节处提供基于电流的负载提示。AnySkin接触检测会触发扳机位置保持,而跟随端关节电流的变化会调整主端伺服输出限制,以在举升过程中指令阻力。在六次UR3会话中,由一名操作者执行,发送指令的跟踪误差为0.15–0.36°均方根误差,估计轨迹延迟为82–98毫秒。在62个分割的TacGELLO抓取区间中,有60个记录了触觉起始时间。在触觉或基于宽度的接触参考之后,TacGELLO的中位指令闭合量为0.7–2.1毫米,而原始界面为13.0–13.9毫米。

英文摘要

Passive leader arms transmit an operator's motion without returning remote contact or load cues. TacGELLO uses the existing servos of a 3D-printed leader for tactile contact feedback at the gripper trigger and current-based load cues at the arm joints. AnySkin contact detection activates a trigger position hold, while changes in follower joint current adjust leader-servo output limits to command resistance during lifting. Across six UR3 sessions with one operator, sent-command tracking error was 0.15--0.36$^\circ$ RMSE, with estimated trajectory lag of 82--98\,ms. Tactile onset was logged in 60 of 62 segmented TacGELLO grasp intervals. Median commanded closure after tactile or width-based contact references was 0.7--2.1\,mm with TacGELLO and 13.0--13.9\,mm with the original interface.
