Development of a surveillance module for hospital robots
Authors: Kabir Mamun, Safayet Rayhan, Robert Sherry, Tamas Szecsi
Abstract
This paper specifies the requirements of sensors for a surveillance module for hospital robots of the IWARD project, identifying the responsibilities for each of these requirements and their application. The IWARD swarm robot is based on an autonomous multi-purpose platform. A modular design philosophy will be adopted to ensure compliance with requirements established within the project, and to allow for ease of modification and/or adaptation, as the project progresses. This includes necessity of different sensors and their specification which will be used for the surveillance modules. The actions to be carried out in the project will ensure the development and establishment of a cost effective solution and a safe and dependable, robust design. Different sensors from each category are compared and selected for the project. The sensors are to be selected based on the limitations and requirements such as data communication, selected operating system and software (Linux, player and orca 2).

Dear Kabir and all,
Your project sounds attractive. But here are my worries:
1. If staff badges are identifiers for the iWARD. How would the iWARD distinquish between a genuine staff member wearing a badge and an impersonator also wearing a genuine badge.
2. It is claimed in the proposal that the camera will follow the movements of an intruder or an illegal person. What would the intelligent camera do when several intruders enter the building and decide to go in different directions?
Cheers.

Dear Flowers,
Thanks for your question!
1.We are trying to make such a badge which will use a unique pattern,size and shape.so there will be less chance to copy it!
2.To me an inturder and an illegal person is same.
There will be more than one Surveillance robot in the real hospital environment.Hope those will be able to handle such situation.
Thanks again.

Hi Everyone,
I am extremely sorry that there was a technical problem with my audio device during recording of my presentation.I am going to upload the update version very soon.
Sorry for any inconvenience.

I realy do like this question. :-)
Maybe, that would just like what we should do when several intruders break in our house.
We will stare at one of them and move eyes to another bad guys.

Dear authors,
The Distance Measurement sensor (i.e. Laser Scanner) was mentioned in this paper.
Dose that Laser safe to patients and nurses?

Dear authors,
page 2.
4. Surveillance module
Apart from the widespread passive infrared (PIR) detectors, glass-break sensors and vibration shock sensors, active systems using infrared light, ultrasound or microwaves are used.
My question is if there are so many vibration shock sensors, will these sensors triggered by the robots themselves frequently?

Xuedong
Hi Xuedong,
Thanks for your post!
This PMD 3D sensor is a Distance sensor with laser class 1.
(Web address:ifm-electronic.com/obj/2_O1D155_e_08_n.pdf)
And from the laser classificication (Web address:en.wikipedia.org/wiki/Laser_safety)
class 1 laser is safe for this application(no hazard during normal use).
(Please check the websites for more details)

Hi Xuedong,
Could you describe more details on your question.Sorry that I am not sure about your question (i.e. what type of applications/scenario/conditions).
"My question is if there are so many vibration shock sensors, will these sensors triggered by the robots themselves frequently?"
Or you can check the 'Reference 1 of my paper' and may find the answer.
Thanks-Mamun
Dear Mr. Mamun,
Thanks for taking the time to answer my questions. I am not certain I am satisfied with the response, though.
1. In addressing the badge issue with respect to impersonators wearing them, you stated that you are "trying" to make badges in such a way that duplicating them would be difficult. The level of strength in the statement indicates that you cannot promise, assure and or rule out the possibility of badge duplication that could beat the intelligence of the surveillance robot. On the other hand, if you apply to use advanced chip-based badges to prevent duplication at all levels, wouldn't this be at very high cost that might not be investment-friendly for a hospital? This is based on the premise that hospitals do not make much money, and as such it is appreciative to consider high-tech quality service products at low investment costs.
2. With reference to my "several intruders going in different directions to confuse the surveillance robot scenario", you offer that there would be more than one robot per hospital environment. How would the cost of investing in a number of surveillance robots to track several intruders compare with that of CCTVs strategically placed in the hospital environment for the same functions?
3. Figure 9 of your paper shows the pioneer robot platform onto which the surveillance module will be attached. How can you assure investors and the end-users that the degree of freedom demonstrated by the design in Figure 9 of your paper can guarantee rapid response even in the face of moving through unfriendly paths such as stairs, etc?
4. Regarding Mr. Xuedong's laser safety question, I agree that Class 1 laser product may be safe if used normally. However, I am not sure Wikipedia is credible enough for your referencing. The Wikipedia administration do not check to validate the facts in the postings by individuals and as such not all materials there may be accurate on the Wikipedia site.
5. Mr. Xuedong observes that there may be several vibration shock sensors as you have demonstrated in both your paper and presentation. His question is in place, in my opinion. Would the surveillance robots themselves play a part in triggering the sensors? In other words, couldn't the robots trigger the vibration shock sensors themselves due to a self-induced shocks rather than shocks created by external factors or elements outside of the robot's body? For instance, if the robot in question comes in contact with an obstacle in its path, the robot will vibrate however small the shock wave may be. If the sensors can capture the slightest vibration or shock, would the robot's contact with a small harmless obstacle trigger the sensor to "trigger an alarm"?
Thanks for your time.

Hi, Xuedong,
I know this triggered your interest again. This is too difficult for those so-called intelligent robots to handle. However, on the other hand, in my opinion, this is not different from the case of handling only one individual intruder. Human beings are able to not only stare at them, but also listen to them. A robot equiped with such sophisticated sensing capabilities and, of course, intelligence would not be worse than human beings. Increasing the number of robots is equal to increasing the sensing abilities. As suggested by the author, hopefully, a well-managed group of robots would be possibly deal with more complicated situations.
Dear Kabir and all,
Your project sounds attractive. But here are my worries:
1. If staff badges are identifiers for the iWARD. How would the iWARD make a distinction between a genuine staff member wearing a badge and an impersonator also wearing a genuine badge.
2. It is claimed in the proposal that the camera will follow the movements of an intruder or an illegal person, I am not sure I got that correctly. Please correct me if I am wrong. What would the intelligent camera do when several intruders enter the building and decide to go in different directions?
