    摘要:

    針對皮膚力傳感器對機器人碰撞點檢測的不足,提出了一種利用六維力傳感器進行機器人本體碰撞點檢測的方法,。該方法利用傳感器采集數(shù)據(jù)進行自約束,,無需依賴碰撞體表面幾何信息,將空間碰撞外力矢量線投影到最優(yōu)平面中進行初步求解,,再代入原始方程進行碰撞點的求解,;引入了誤差因子,,以保證計算結(jié)果的絕對誤差最小,;在數(shù)據(jù)預處理方面,,提出了一種動態(tài)力補償算法,以保證基座處六維力傳感器在機器人運動過程無外力碰撞下的讀數(shù)恒為零,,當傳感器的數(shù)值超過一定閾值后即可認為機器人與外界發(fā)生碰撞,。對本文提出的算法進行了仿真實驗,結(jié)果表明,,動態(tài)力補償算法的合力最大相對誤差為4.8925%,,碰撞點檢測算法在實驗距離最遠598.61mm處誤差最大,為8.7119%,。本文提出的動態(tài)力補償算法的精度隨碰撞點距離的增加沒有明顯變化,,但在碰撞力一定時,隨著碰撞距離的增加相對誤差不斷增大,。

    Abstract:

    Aiming at the shortcomings of the skin force sensor to detect the collision point of the robot, a method using the six-axis force/torque sensor to detect the collision point of the robot body was proposed. The sensorcollected data was used for selfconstraint, without relying on the geometric information of the collision body surface. The space collision external force vector line was firstly projected into the optimal plane for preliminary solution, and finally brought into the original equation to solve the collision point. In order to ensure that the absolute error of the calculation result was the smallest, an error factor was introduced. In terms of data preprocessing, a dynamic force compensation algorithm was proposed to ensure that the six-axis force/torque sensor at the base had a constant reading of zero when there was no external force collision during the robot movement. The robot can be considered collide with the outside world when the sensor value exceeded a certain threshold. Finally, a simulation experiment was performed on the proposed algorithm. The experimental results showed that the maximum error of the dynamic force compensation algorithm was 4.8925%, and the collision point detection algorithm had the largest error at the experimental distance of 598.61mm, which was 8.7119%. The experimental results showed that the accuracy of the proposed dynamic force compensation algorithm was not changed significantly as the distance of the collision point was increased, but the relative error of the collision point detection algorithm was increased with the increase of the collision distance when the collision force was constant.
