RIBA robot nurse bear
by: Shaniya Head
What task does the robot perform,What human function or task does this robot simulate
Designed primarily to assist nurses by lifting patients in and out of their beds and wheelchairs (as well as on and off the toilet), the 180-kilogram (400-lb) robot can safely pick up and carry people weighing as much as 61 kilograms (135 lbs. The soft skin is designed to ensure the comfort of patients while they are being carried. In addition, the arm joints yield slightly under pressure -- much like human arms do -- further increasing the level of comfort and safety.
Where is the robot used? What is its work envelope.
It is used in the hospital. lifting patients in and out of their beds and wheelchairs (as well as on and off the toilet), the 180-kilogram (400-lb) robot can safely pick up and carry people weighing as much as 61 kilograms (135 lbs.). It has multi-jointed arms embedded with an array of tactile sensors that help it optimize the lifting and carrying of humans. For safety purposes, RIBA's entire body is covered in a soft skin molded from an advanced lightweight urethane foam developed by TRI. The soft skin is designed to ensure the comfort of patients while they are being carried. In addition, the arm joints yield slightly under pressure -- much like human arms do -- further increasing the level of comfort and safety
How is the robot taught to perform its task
The robotic bear can also recognize faces and voices, as well as respond to spoken commands. Using visual and audio data from its surroundings, RIBA can identify co-workers, determine the position of those nearby, and respond flexibly to changes in the immediate environment. The motors operate silently, and a set of omni-directional wheels allow the robot to navigate tight spaces inside hospitals and nursing facilities.
What sensors does the robot have and how does the robot use these sensors
Equipped with actuator units with a very low gear ratio, the robot’s joints can move quickly and with precision. The system incorporates three types of sensors, including torque sensors and tactile sensors made entirely of rubber, ensuring the robot can perform power-intensive tasks such as lifting the patients but still be gentle enough not to hurt them
some advantages and disadvantages of using a robot to complete this task
Advantage: easier and safer for both the patient and the doctor or nurse
Disadvantage : they could fall through the arms.
Describe the impact that this robot has had or could have on its intended audience
It is saving physical harm for hospital workers.
What type of jobs/careers can this robot create to provide employment for people?
It would provide jobs for the people making the robots.
Predict and explain how this robot may be altered to perform more or different tasks in the future.
In the future it will be altered to be able to lift more weight.
