  • Behavior-based robotics is quite simply the design of robots where there are no internal "models" of the environment. Instead, the robot's action is state-machine driven via inputs gleaned from the robot's sensors.

Behaviour Based Robotics & Deliberative Robotics - 0 views

behavior-based robot

shared by York Jong on 30 May 07 - Cached
  • The robots do not build a model of their world they simply act in response to the things they encounter whilst existing there.
  • This form of robotics has proved to be successful in environments that are unknown to the robot, environments that are busy or noisy such as a place with moving objects or people
  • An important part of the behaviour based theory is "embodiment" This means that a robot must be embodied, have a presence (it is an entity in itself).  In order to react the robot must be surrounded by the real world.
  • ...2 more annotations...
  • Alan Turing the inventor of the Turing Test might have been the first to recognize this, in a paper he wrote in the mid 1940's entitled "Intelligent Machines" he suggest that for a machine to achieve some levels of intelligence (his example was" language") it must be embodied.
  • Testing a behaviour based systems is quite different from deliberative systems.  You can test individual parts of the system, you are able to build up the behaviours the robot will have and then test each for correctness.

  • This book provides far more detail on the hardware aspects of robot building than any other I have seen to date and is worth picking up.
  • "Intermediate Robot Building" offers the kind of real-world knowledge that only an experienced robot builder can offer--the kind of knowledge beginners usually have to learn through mistakes. In this book, you'll learn the value of a robot heartbeat and the purpose of the wavy lines in photocells.

    Intermediate Robot Building by David Cook covers all aspects of robot building, from mechanical, to electronics, to microcontroller selection.

  • three-layer systems.
  • if a robot needs to plan ahead, it does so in a network of behaviors which talk to each other and send information around, rather than a single planner, as with hybrid systems.
  • Deliberative Control: Think hard, then act. Reactive Control: Don't think, (re)act. Hybrid Control: Think and act independently, in parallel. Behavior-Based Control: Think the way you act.
  • York Jong on 26 May 07
     
    Robot control refers to the way in which the sensing and action of a robot are coordinated. There are infinitely many possible robot programs, but they all fall along a well-defined spectrum of control. Along this spectrum, there are four basic practical

mechanics robot tutorial wheel

shared by York Jong on 31 May 07 - Cached
  • Large diameter wheels give your robot low torque but high velocity. So if you already have a very strong motor, then you can use wheels with larger diameters.
  • But if your motor is weak (such as if it does not have any gearing), you want to use a much smaller diameter wheel. This will make your robot slower, but at least it has enough torque to go up a hill!
  • Wheel width. You do not want it too wide as it causes increased resistance to rotating the wheel on a surface.
  • ...1 more annotation...
  • Make sure you get a motor which already has a gear box attached, as it makes your robot much better controlled, more efficient, and stronger.

PHOTORESISTOR ALGORITHMS - 0 views

algorithm photoresistor photovore robot sensor

shared by York Jong on 14 Jun 07 - Cached
  • pseudocode: read left_photoresistor read right_photoresistor if left_photoresistor detects more light than right_photoresistor then turn robot left if right_photoresistor detects more light than left_photoresistor then turn robot right if right_photoresistor detects about the same as left_photoresistor then robot goes straight loop
  • Photovore Algorithm, Improved This algorithm does the same as the original, but instead of case-based it works under a more advanced Fuzzy Logic control algorithm. Your robot will no longer just have the three modes of turn left, turn right, and go forward. Instead will have commands like 'turn left by 10 degrees' or 'turn right really fast', and with no additional lines of code! pseudocode: read left_photoresistor read right_photoresistor left_motor = (left_photoresistor - right_photoresistor) * arbitrary_constant right_motor = (right_photoresistor - left_photoresistor) * arbitrary_constant loop
  • ...1 more annotation...
  • Photovore, Split Brain Approach This algorithm works without comparison of photoresistor values. Instead, just command the right motor based on light from the right sensor, and the left motor with only data from the left sensor. You can also get interesting variations by reversing the sensors for a cross-brain algorithm. pseudocode: read left_photoresistor read right_photoresistor move left_wheel_speed = left_photoresistor * arbitrary_constant move right_wheel_speed = right_photoresistor * arbitrary_constant loop
  • York Jong on 14 Jun 07
     
    The photovore is a robot that chases light, and is perhaps the simplest of all sensor algorithms. If you are a beginner, this should be your first algorithm.

  • Motorcycle lead acid batteries work great for larger low performance type robots. They are great for solar power robots too.
  • lead acid batteries have the serious problem of being very large and heavy, need to always be kept charged, and do not have the high discharge rates as the more modern batteries.
  • They have low power capacities, are heavy, have trouble supplying large amounts of current in short time periods, and get expensive to constantly replace
  • ...6 more annotations...
  • Li-ion batteries have the same high energy capacity as NiMHs, power output rates of NiCads, and weigh about 20%-35% less. They also have zero memory effect problems, meaning you can recharge whenever
  • NiCad (Nickel Cadmium) batteries are good for small to medium size range robots. They have the highest current output, are more affordable than NiMH's, and can be recharged within one or two hours
  • A NiCad, over many charges, can only store less and less energy after each recharge. To prevent memory effect, whenever you wish to recharge your NiCad, you must first fully discharge it.
  • NiCad batteries contain toxic cadmium stuff, so save a squirrel and recycle/dispose of it properly.
  • NiMH battaries can last many more cycles than your typical NiCad battery.
  • they have good current output, and have the highest energy capacity. I would recommend them for small size robots and for powering circuits. Note, NiMH batteries usually take like 10 hours to recharge depending on various factors.

SENSORS - SHARP IR RANGE FINDER - 0 views

ir range rangefinder sensor

shared by York Jong on 01 Jun 07 - Cached
  • The Sharp IR Range Finder works by the process of triangulation. A pulse of light (wavelength range of 850nm +/-70nm) is emitted and then reflected back (or not reflected at all). When the light returns it comes back at an angle that is dependent on the distance of the reflecting object. Triangulation works by detecting this reflected beam angle - by knowing the angle, distance can then be determined.
  • The IR range finder reciever has a special precision lens that transmits the reflected light onto an enclosed linear CCD array based on the triangulation angle.
  • The Sharp IR has a non-linear output. This means that as the distance increases linearly (by set increments), the analog output increases/decreases non-linearly.
  • ...10 more annotations...
  • To effectively use your Sharp IR Range Finder, you must have a voltage output versus distance chart to reference from.
  • One major issue with the Sharp IR Range Finder and that is going below the minimum sensor range. This is when an object is so close the sensor cannot get an accurate reading, and it tells your robot that a really close object is really far.
  • Another issue is the high narrowness of the IR beam. In reading sharp details and getting high accuracy, a thin beam is ideal. But the problem with a thin beam is that if it is not pointed exactly at the object, the object is therefore invisible.
  • A more advanced use for the Sharp IR Range Finder is to do mapping. To do this, you need at least one Range Finder, and at least one non-modified servo.
  • The sharp IR can be used as a quick and easy front non-contact robot bumper on your robot. Just place two IR devices in front of your robot and cross beams as shown. Ideally you would perfer to use rangers that have wider beams. Note: A single sonar can do this job just as well.
  • For example, a box in front of your robot might appear like this: 0 0 0 0 0 106 120 124 121 109 0 0 0 0 0
