Hardened Operator Control Unit (HOCU). The HOCU is an environmentally sealed 10 DoF tele-operation unit. A remote operator can use a single hand to control the three translational DoF for the end effector, three rotational DoF for the end effector, the flexion of the two fingers and thumb, and the opposition of the thumb.
HDT’s Hardened Operator Control Unit (HOCU) tele-operates a single arm and end effector. Two HOCUs can be used to tele-operate a dual arm system. The HOCU is an environmentally sealed 10 DoF tele-operation unit. A remote operator can use a single hand to control the three translational DoF for the end effector, three rotational DoF for the end effector, the flexion of the two fingers and thumb, and the opposition of the thumb.
- The HOCU operates either wirelessly or in a wired configuration
- HDT can supply a variety of radios depending on the application
- The HOCU receives, and can display, the telemetry from the arm, including diagnostic codes and joint forces
- There are several advantages to using a HOCU rather than a VR glove
- The HOCU provides a rest point for the operator’s arm and hand. Holding a pose with a VR glove in midair can become tiring after a few minutes
- The HOCU is truly rugged, operating in rain, extreme heat, or noisy electromagnetic environments
- For tele-operation of an Adroit® arm, HDT supplies software that provides a game controller interface
- The game controller can be used for end-point control and basic end effector grasping motions
- Getting the best tele-operative control of HDT’s highly dexterous three-fingered hand requires a master/slave relationship between the operator’s hand and the robot’s end-effector
- Virtual reality (VR) gloves can also offer good results
- For autonomous control of an Adroit arm, no special controller is needed
- Adroit arms accept both CANbus and Ethernet communications
- A simple communications protocol is used to send commands to the arm and receive information back from the arm. This protocol is compatible with the Robotic Operating System (ROS), JAUS/AS-400, and the U.S. Army Inter-Operability Protocol (IOP).
Highly dexterous end effector. A VR glove or HDT’s HOCU allows tele-operators to get the best performance possible from our highly dexterous end effector.
