Project Information
Project Title: Incredible Ball (An Autonomous Omnidirectional Surveillance Robot)
Hardware & Software Used: NI Robotics Starter Kit & LabView 2012
What challenge/problem are you trying to solve through your application:
Manned surveillance missions are critical,to obtaining useful intelligence. But sending a soldier into sensitive areas can often be too dangerous. Thus,Our Robot is prove to be an efficient Serveillance Robot To mitigate this problem.
How does your application solves the above mentioned challenge/problem:
The spherical design is simplicity itself. With its large circumference,The Robot will able to operate in most terrains including deep snow, ice,water,mud and sand and also to navigate through slopes and stairs.And yet its appearance is friendly and unthreatening. Inside, all cameras and sensors are sealed off from the outside world. This means that they are protected from bangs and knocks. In addition, the outside world is protected from potential electrical sparks when the Bot is investigating gas leaks.
Thus,Incredible Ball could overcome many of the problems that affect mobile robots with wheels.
Description of Project:
Robots are by nature sophisticated pieces of technology. But that’s no reason why they should be complicated to use or difficult to own. Manned surveillance missions are critical to obtaining useful intelligence. But sending a soldier into sensitive areas can often be
too dangerous. Scientists are developing robots that could do the job. In recent years, there has been increasing interest in the design of spherical mobile robots. The spherical design is simplicity itself. With its large circumference,The Robot will able to operate in most terrains including deep snow, ice,water,mud and sand and also to navigate through slopes and stairs.And yet its appearance is friendly and unthreatening. Inside, all cameras and sensors are sealed off from the outside world. This means that they are protected from bangs and knocks. In addition, the outside world is protected from potential electrical sparks when the Bot is investigating gas leaks.
For the actuation and movement of the bot we are using a hanging pendulum that offsets the center of mass of the sphere. In this,it has a shaft that is fixed to two sides of the shell and has a hanging mass from the center.
A number of advantages are associated with this robot. First, the total symmetry of a sphere blurs the distinction between forward, backward, and sideways, which means that sphere-bots have the potential to be truly omni-directional. Second, the larger diameter of the effective wheel created by a spherical shape means that more rugged terrain can theoretically be handled by a sphere bot than by an equally sized robot with ordinary wheels. Third, the lack of exposed parts and a strong outer shell creates the potential for an extremely robust robot. Thus, a successfully designed sphere-bot could overcome many of the problems that affect mobile robots.
The Bot will be used in a wide range of duties including automated patrolling of larger areas, tele-operated surveillance, inspection of remote or dangerous sites, live projection video conferencing and monitoring of explosive gases.
The bot can be made to Controlled remotely, Computer Controlled or via a programmed autonomous GPS-based system, The bot size is comparable to an automobile tire, measuring 40-50cm(in diameter), while weighing in at 20-25kg Approximately.
The Bot will be equipped with a large number of different cameras and sensors:
- Wide-angled cameras – 360° vision
- Night vision (IR) cameras
- Projector and display screen
- Microphone and loudspeakers
- GSM and GPS module
- Ultrasonic sensor
- Sensors for gas or smoke detection, explosive weapon.
- Lipo, NICd Batteries can be used for the operation of the robot as these were light in weight and easy to use.
FEASIBILITY IN LONG RUN As the robot features stand itself an innovation in the field of technological advancement, this robot will change the living style of the people and also proves to be an efficient autonomous Surveillance robot in long run.
IMPLEMENTATION :
Motion :
The Motion or Actuation of the robot is controlled through a hanging pendulum that offsets the centre of mass of the sphere. It has a shaft that is fixed to two sides of the shell and has a hanging mass from the centre. This mass is torqued such that the centre of mass of the entire robot moves in the direction of desired motion. Because of gravity pulling down on the centre of mass, the sphere then rotates until the centre of mass is directly above the contact point of the sphere with the ground. The Movement of the pendulum is done using 3 Stepper motor assembly (2 for the forward/reverse and 1 for left right movement).The transmission is done through Bluetooth device and the controlling can be done using Computer keyboard, remote and an autonomous GPS based system using LabView Robotics. And for this ARM cortex M3 controller is proposed to be used.
Image/Video Capturing And Transmition :
Monitoring : 2 Wide-angled wireless camera(night vision) having 360° vision with microphones/mike are positioned at two sides of the spherical bot. The Transmission is done through a control unit at the bot and the received image/video data is displayed on the Computer/P.C Screen using LabView Robotics Software.
X-Ray Monitoring/Metal detection : Governments worldwide spend millions of dollars every year to stop terrorist activities specially in airports. Through X-ray monitoring, we are able to detect if there is any weapon with the person or not. The process is being mobile through the robot, hence the process of checking individual person with wastage of time can be overcome. So, if possible we can come up with a small x-ray monitoring device or metal detector in our robot to do the desired job. The transmission is done through a ARM based controlling section and can be processed using LabView Robotics software and is displayed on Computer screen.
Proximity Detection:
A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. Thus, using this we can detect the presence of any nearby object of the robot and then we can take measures regarding the change in the direction of the bot and can also apply certain programmed logics embedded in the Robot using Labview Robotics.
Wireless Live Video Conferencing:
The implementation of video conferencing is one of the important feature in our robot. This can be done using a smartphone having live projection feature. The live conferencing can be done using skype or teamviewer software application. The video/image and sound of the person in front of the robot camera is transmitted to the robot controller Computer screen using skype or teamviever, the video/image & sound of the robot controller person is sent through the webcam to the smart phone and the projector inside the smart phone or an external projector, display the controller video/image & sound. The display screen is inscribed in the robot and when there is a need of video conferencing it will comes out of the robot. The controlling section is done using Labview Robotics.
Gas or Smoke Detection :
Smoke/Gas sensors used commercially to detect different gasses can easily be fabricated inside the robot. The controlling and transmission of data is done through Labview and Arm controller.
Location Detection :
Using GPS and GSM module in our robot we are able to find out the exact location of the robot. The location can easily be displayed on our Computer screen.
