Robotic sensing is the subarea of robotics science intended to give the robots sensing capabilities so that the robots are more human-like, Robotic sensing mainly gives the robots the ability to see, touch, hear and move and it uses algorithms that require the environmental feedback. The sensor is the sophisticated device which measures the physical quantity such as the speed or the pressure and it converts it into the signal which can be measured electrically, The sensors are based on several working principals and types of measurements, almost all types of sensors emit the signals and measure the reflection to make measurements.

The sensors provide analogs to the human senses, They can monitor other phenomena for which the humans lack explicit sensors and they can measure the physical properties such as the distance between the objects. The sensors can measure the presence of light and the frequency of sound, They can measure the object proximity, They can measure the presence or the absence of the object, bearing, the color and the distance between the objects.

The sensors can measure the presence and concentration of chemicals or reactants, They can measure the presence, color and intensity of light, They can measure the presence, frequency and intensity of sound.

The accuracy is very important in detecting and tracking the objects, Environmental condition affect on the sensors such as the temperature and the humidity, you can select the sensors that can be used to build the robot. Robotic sensors. The presence of the object can be detected with the proximity sensors, There are many sensors such as the ultrasonic sensors, the capacitive, the photoelectric, the inductive or the magnetic, Tracking the objects can work using the proximity sensors ultrasonic sensorsfor the advanced applications generally it is used the image sensors webcams and the vision software like OpenCV.

The sensors are used in the industrial robotics for monitoring the dangerous and safety conditions in the robot cell layout, They help in avoiding the physical injuries and other damages caused to the human workers.

In the robot work cell, the series of activities of various equipments are controlled by using the interlocks, The sensors are used to verify the conclusion of the current work cycle before progressing to the next cycle.

The quality control was performed with the manual inspection system, Nowadays, The sensors are used in the inspection process to determine the quality features of the work part automatically, The sensors provide high accurate results but the sensors are only able to examine the limited variety of work part features and faults.

T he image quality is important in the applications which require excellent robotic vision, Algorithm based on the wavelet transform for fusing the images of different spectra and different foci improves the image quality, The robots can collect more accurate information from the resulting improved image. The visual sensors help the robots to identify the surrounding and they take appropriate action, Touch sensory signal is useful to identify the external tactile signals for the accurate operations, Touch patterns enable the robots to interpret the human emotions in interactive applications.

The robots use touch signals to map the profile of the surface in hostile environment such as the water pipe, The predetermined path was programmed into the robotwith the integration of touch sensors, The robots first acquire the random data point. The accurate audio sensor requires low internal noise contribution, audio sensors combine the acoustical arrays and the microphones to reduce the internal noise level.

Asked in Military Equipment, Robotics Do military robots have sensors? Yes, of course. Without sensors any robot is not able to search, find, indentify or even to move in difficult area. Sensors are important to receive feedback for the human, who is steering a robot. If robot is at automatic drive no human is steering - only on software running sensors are also very important to the robot to get any information about the outside, the surrounding of it.

Robot sensors detect different things and send different amounts of electricity to the Robot's controller board to tell their findings. Then the controller board uses these different amounts of electricity to interact with its surroundings.

Example: Lets say you have a robot that is made to follow light. Lets say your robot has 3 light sensors. One in the front of your robot one on the right and one on the left side. The sensors will detect how much light is on the front, right, and left sides and send this data to the controller board. Then the controller board uses this data to tell the robot with direction to go.

David Ian Flynn has written: 'Use of magnetic recording technology in robot sensors'. Asked in Robotics What parts does a robot have?Robots are very useful nowadays. One of the most common robots is the mobile robot, capable of moving around in their environment and not just fixed into one physical location. Robots are also used in education, military, mining and research. But most importantly, robots are now becoming useful in the medical world.

According to CKNWmedical robots are changing the healthcare. Sheffield University professor Noel Sharkey is a robotic expert and narrate how a patient's normal hospital visit and their treatment has been changing through the years. Sharkey cited St. George's Hospital in Scotland as an example. He said that it is a robot hospital which means that robots are doing assistive works like delivering patients to the surgery and doing laundry.

Normally, a medical staff would fetch a patient to bring to the surgery room. But with the use of these robots, a medical staff would just load the patient to the trolley and the robot will bring the patient to the surgery room.

Robotic sensors

Robots are also very useful during an actual surgery. But aside from being useful in surgeries, Sharkey said that medical robots are also capable in helping out in patients that needs rehabilitation.

For example, if a patient needs to move his arm or legs for times a day and it needs to be guided. If a person does that every day, it will be quite tiring. This is where medical robots could help because they don't get tired or lose patients. They are machines after all. In Australia, Queensland University researcher Nicole Robinson is conducting the first Australian study that could have a positive impact of robots in a person's eating habits, as per Gizmodo Australia.

If this will become a success, robots could also help in weight loss programs. Nurses, technicians and physicians will still be the backbone of the medical world. However, these medical robots will help hospitals in saving cost, reducing waste and improving patient care. Because the role of modern technology is to improve our quality of life.

Hope This Helps :.A key driver for this growth is demand for using robots in minimally invasive surgeries, especially for neurologic, orthopedic, and laparoscopic procedures. As a result, a wide range of robots is being developed to serve in a variety of roles within the medical environment. Robots specializing in human treatment include surgical robots and rehabilitation robots. The field of assistive and therapeutic robotic devices is also expanding rapidly.

Additional applications for these surgical-assistant robots are continually being developed, as more advanced 3DHD technology gives surgeons the spatial references needed for highly complex surgery, including more enhanced natural stereo visualization, combined with augmented reality. Rehabilitation Robots These play a crucial role in the recovery of people with disabilities, including improved mobility, strength, coordination, and quality of life. These robots can be programmed to adapt to the condition of each patient as they recover from strokes, traumatic brain or spinal cord injuries, or neurobehavioral or neuromuscular diseases such as multiple sclerosis.

Virtual reality integrated with rehabilitation robots can also improve balance, walking, and other motor functions. Medical Transportation Robots Supplies, medications, and meals are delivered to patients and staff by these robots, thereby optimizing communication between doctors, hospital staff members, and patients.

Sanitation and Disinfection Robots With the increase in antibiotic-resistant bacteria and outbreaks of deadly infections like Ebola, more healthcare facilities are using robots to clean and disinfect surfaces. Robotic Prescription Dispensing Systems The biggest advantages of robots are speed and accuracy, two features that are very important to pharmacies. Advanced robots continue to be designed for an ever-expanding range of applications in the healthcare space.

For example, a research team led by Gregory Fischer, an associate professor of mechanical engineering and robotics engineering at Worcester Polytechnic Institute, is developing a compact, high-precision surgical robot that will operate within the bore of an MRI scanneras well as the electronic control systems and software that go with it, to improve prostate biopsy accuracy. To develop robots that can work inside an MRI scanner, Fischer and his team have had to overcome several significant technical challenges.

Since the MRI scanner uses a powerful magnet, the robot, including all of its sensors and actuators, must be made from nonferrous materials. This all added up to a massive systems integration project which required many iterations of the hardware and software to get to that point.

In other research, virtual reality is being integrated with rehabilitation robots to expand the range of therapy exercise, increasing motivation and physical treatment effects. Exciting discoveries are being made with nanoparticles and nanomaterials. Soon, ingestible, broadband-enabled digital tools will be available that use wireless technology to help monitor internal reactions to medications.

how do medical robots use their sensors

Robots are becoming smarter. In the factory, industrial robots have to sense the presence of human workers to avoid possible injuries to them.

They should also be able to detect abnormal situations, such as excessive vibration, that could cause damage. Service robots that are either safe-guarding a warehouse or acting as a telepresence device for a remote person need to navigate autonomously. Just like we use our natural senses, robots need sensor technologies to help them become smarter, safer to use, and more useful to humans.

MEMS sensors are amazing little devices, just a few square millimeters in size and typically packed with two dice. One is the sensor die itself, typically a MEMS device providing, say, motion or pressure information, but it could also be a magnetic solid state sensor. The other die provides the signal-processing function needed to convert the very small analog signal coming from the sensor into usable information that can be communicated over some serial bus see Fig.

The small size and affordable price of these sensors make them ideal pieces of technology for use in robots. They are small and inexpensive because they are sold in the hundreds of millions into smartphone and other consumer gaming applications. They also consume very little power.

The fast wake-up and shut down mechanisms they provide are then the most important parameters influencing power consumption. Power savings techniques will vary depending on the application needs and the requested frequency for taking data points.

For space-constrained applications, robot designers can also choose an accelerometer with built-in microcontrollers and memory to build very small systems with customized software see Fig. These sensors are frequently referred to as sensor hubs, since they also often offer the ability to connect additional sensors without needing additional processors.

The Freescale Xtrinsic MMAL, for instance, offers a 3 x 3-mm three-axis accelerometer and a bit microcontroller with 14 Kbytes of flash and 1.

This sensor and others like it could be useful when the sensors would need to be placed in robot end-tips or arm segments, where space is very tight. Another application could be to design very small robotic systems that could be worn, or even a robotic capsule that could be swallowed for endoscopic medical applications see Fig.

The on-board memory and microcontroller in such device could also be used to implement a sensor communication protocol, such as IO-Link. This increasingly popular sensor network protocol requires around 10 Kbytes of memory and could therefore be integrated in this small form factor, enabling new sensor-node designs and form factors. So a linear-motion sensor accelerometer needs to be added to sense tilt movement and compensate the magnetic sensor reading using some trigonometric algorithm.

A good electronic compass will be designed with both these sensors.

An even better system would encompass these sensors integrated into the same package, resulting in a smaller sensor. The precision of this system can be enhanced by adding a very small altimeter sensor, such as the Freescale Xtrinsic MPL With a relative altitude resolution of about 30 cm 1 ftthis sensor will easily detect the phone traveling up or down a floor within the building.

This simple information can be very useful to simplify or validate the results of the complex triangulation algorithm. A surveillance robot watching an outdoor facility will also need to know if it is moving up or down floors, which will have an impact on its speed or power consumption; this is important data to take into account for its autonomy duration.

This approach could be used in robots that must operate in similar non-GPS environments. Another sensor-fusion function you can implement with an altimeter is shock detection. Autonomous robots that move around a warehouse floor or a hospital hall are designed not to bump into people or objects, but in case this happens, the robot needs to be able to detect the collision. Still another great technology to help autonomous robots navigate and avoid obstacles is image recognition. Vision systems exist today that can recognize shapes, objects, or even human faces.

A moving robot will want to create a real-time 3D map of its surroundings to determine any possible obstacles. A camera will work as long as the visibility or light conditions are good enough for the image sensor to capture enough relevant data. But in outdoor conditions, vision system capability could be limited by snow, fog, or other weather incidents.Tekscan, Inc. Due to advances in electronics and technology, robotic surgery has become increasingly popular. Surgeons no longer have to operate directly on a patient, but instead can control a robot to carry out the procedure.

Robotic surgery has benefits to both the surgeon and the patient. For the surgeon, robots display 3D visualization for enhanced viewing of the operative area and improve the control, precision, and range of motion of smaller instruments. While robotic surgery may seem like the future of the medical industry, it still has obstacles to overcome.

One significant disadvantage to robotic surgery is the lack of haptic technology, which provides physical sensations that enable electronics to give their users force feedback. Because many medical devices and surgical tools, such as grippers and laparoscopic instruments, do not provide tactile sensation, there is no way for a surgeon to sense how much force is being applied when using the instrument during robotic surgery.

This innovative new device receives force feedback from a force-sensing resistor FSR integrated into an instrument and provides an enhanced level of tactile feedback. This force feedback allows robotic operators to perform surgical operations that had previously been problematic and dangerous.

Robotic sensing (Robot Sensors) uses, types & importance

This sensor-enabled grasper is connected to the haptic interface worn by the surgeon. The FSR can then measure applied force, which is read by the haptic interface and translated into pressure applied by the device through the use of a mechanism that moves up and down in response to force.

See Figure 1 The brain rapidly associates the pressure being applied by the Neo with a sense of touch, enabling the surgeon to adapt his or her use of force in response to pressure from the Neo.

The integrated sensor is so small and thin, it is possible for the device to provide a full range of tactile sensation without having to increase the size of the instrument being used. Sensors can be produced in a variety of shapes and sizes to meet a wide range of design requirements, making it easy to integrate into a device. And, unlike load cells and strain gauges, these sensors do not require complex electronics to obtain output data.

With this new haptic interface, we feel we are providing a solution that will lead to new and exciting capabilities from the surgery room to space. Pen and Autoinjectors: Testing for the Future. Home Medical Article. Top Stories. Inside Story Allied Motion. Trending Stories.
