The purpose of the testing was for them to identify obvious shortcomings of the system to be fixed before consumer testing begins. An issue that a tester mentioned as being troublesome. A level assigned to a problem indicating the importance of a solution. Indicates how often the problem was mentioned. In certain configurations, the radial master movement is difficult.
Custom make master unit for user.
When system is mechanically recalibrated for a particular task, a kinematic mismatch results. The user is trying to do tasks wrt the slave, but the master and slave no longer align. Can not disengage from master in any position without the system going unstable. Hence, the slave drives the master to a position where the feedback loop of the radial motion takes over. Some tasks are difficult without gripper pitch capability or special gripper adaptations.
