我用了franka的7轴机械臂去训练一个lift 任务,训练完成的效果还好,play策略时也能正常执行,但是我打印策略输出的actions数据时,发现actions的数据与实际有差异(或者说我无法理解actions输出的数据)

在actions定义中,是有8个维度,其中arm_action(7) : joint_positon_action , gripper_action (1): binarry_action
所以按理来说,输出的actions 是机械臂七个joint的关节位置加上一个夹爪的开闭位置

但是在实际输出的数据中,机械臂的pose数据很怪,甚至超出了limit ,而且夹爪的位置数据也不知道怎么理解,主要是在做sim2real时,这一部分的actions不知道要怎么处理发给显示世界的机械臂。
