The present disclosure relates to systems and methods for improving 3D eye-hand coordination accuracy of a robotic system. One embodiment can provide a robotic system. The system can include a machine vision module, a robotic arm including an end effector, and a robot controller configured to control movement of the robotic arm to move a component held by the end effector from an initial pose to a target pose. In controlling the movement of the robotic arm, the robot controller can be configured to move the component in a plurality of steps. The displacement of the component in each step is less than or equal to a predetermined maximum displacement value.

The application relates to a projector mounting device and a projection equipment, the mounting device comprising a bearing platform, a convex piece and a locking piece; the bearing platform is configured to bear a projector, the bearing platform is provided with a positioning slot, the positioning slot comprises a clamping position; the convex piece can be inserted into the positioning slot and slid along the positioning slot to the clamping position, and is configured to be connected with the projector; the locking piece is arranged on the bearing platform and is configured to lock the projector to the bearing platform when the convex piece is located in the clamping position. The traditional alignment of the projector and the bearing platform relying on eyes and hands is replaced by mechanical cooperation alignment of the positioning slot and the convex piece, the installation efficiency of the projector is improved, and the risk of projector installation deviation can be reduced.

The present disclosure relates to a computer-implemented method for monitoring eye-hand coordination of a user of a digital writing instrument, comprising: monitoring the location of a writing tip of the writing instrument during a writing session with the writing instrument; monitoring the eye location of the user during the writing session; generating data by correlating the locations of the writing tip and of the user's eyes; comparing the generated data to historical data from the user; providing an indication in case that data of a current writing session of the user deviates from an average of historical data from the user; and storing generated data as historical data.

The utility model discloses a multifunctional hand fine motion training teaching aid which comprises a storage mechanism, one side of the storage mechanism is provided with a rotating mechanism, and the storage mechanism is provided with a throwing mechanism and a stringing rope; through cooperative use of the storage mechanism and the throwing mechanism, training of ball throwing, shape pairing, stick inserting and color pairing can be performed, and color cognition and eye-hand coordination ability can be trained; through the arrangement of the rotating mechanism, digital rotation training can be carried out, and the digital cognition and grabbing ability can be trained; through cooperative use of a stringing mechanism and a partial throwing mechanism, bead stringing training can be carried out, the grabbing capacity can be enhanced, then action training can be carried out on hands with different difficulties according to the fine development condition and age of the hands of an infant, and the training effect can be improved; meanwhile, when the storage mechanism is in an open state, the storage mechanism can be used as a toy car to improve the playing interest of the infants, and when the storage mechanism is in a closed state, the storage mechanism can be used as a storage box to store the putting mechanism.
