Abstract
A tactile or haptic guidance device incorporates a LIDAR assembly and servo motor assembly or linear actuators to provide tactile feedback to the user. The LIDAR assembly determines obstacles in the path of the user and the micro-controller uses the LIDAR data to send a signal to the servo motor assembly or linear actuators, which will cause translational or rotational movement along one or more axes with appropriate amounts of force to provide tactile feedback to the user about objects in their path.
Claims9
A tactile responsive guidance device, comprising:
- a. a LIDAR sensor for detecting objects in front of the device;
- b. a controller;
- c. a three-servo motor cube assembly;
- d. an inertial measurement unit for sensing the current orientation of the device, sensing any changes in movement of the device, and for communicating with the controller;
