    The Ants are a community of cubic-inch microrobots at the MIT Artificial Intelligence Lab. There are two main goals for this project. The first is to push the limits of microrobotics by integrating many sensors and actuators into a small package. The second is to form a structured robotic community from the interactions of many simple individuals. The inspiration behind this idea comes from nature -- the ant colony.

  • Usually, the operating system takes all the values from the sensors, averages them, then finds the one that is the furthest away from that average
  • The Ant Farm is built next to a very large window that faces east. As a result, with the lab lights off, the brightest light source is always to the east. The robots can use this as a reference and then find all the other directions.

  • All of the procedures take a discrete ``gear'' to specify the speed. The reasons for this are two-fold; first, by limiting the power of the truck, we simplify the interface to children. Secondly, it allows use to calibrate the ``gears'' so that, for example, 10 seconds forward in first gear is the same distance as 10 seconds backward in first gear.
  • The limitation of LOGO however is the lack of feedback from the environment. There is no way of expressing an event occuring in the outside world.
  • Simple constructs in iLogo extend the original LOGO language with interactivity capabilities of reading sensors and transfering control to different parts of the program.
  • ...6 more annotations...
  • These above rules handle all of the commands and expressions of the iLogo language except for the DoUnlessCommand. This command will execute a list of commands unless a boolean condition is met. If so, control is switched to a new list of commands for handling the exception condition.
  • Each stage of the compiler is designed using the Visitor pattern described in the book Design Pattern by Eric Gamma, et al. This pattern allows tree traversers to be created as seperated objects, instead of doing all traversals as methods of the nodes of the tree
  • We decided to use the JavaCC/JJTree tools created by Sun for generating a custom parser for our iLogo language written in Java.
  • The language must have primitives which allow the user of the language to write programs which easily transfer control based upon outside stimuli, in this case sensors on the truck.
  • An LM18293 push-pull motor driver connects the programmable counter array (PCA) of the 8051 to the truck's motors.

      LM18293 is a DC motor driver.
  • We took the Berkeley Logo language design as our base and then added a primitive for reading sensor and an exception-based control structure.

    RoboLogo is a system that enables children to program interactive robots. Children can program a robotic truck that interacts with the environment without having to deal with low-level implementation details.

  • This chip is great for building robots because it has extensive input/output hardware built right into the chip. This reduces the need for external components.

  • the Cricket's yellow LED flashes when the Cricket is sending infrared signals.
  • You can type any Cricket Logo instruction in the Cricket Logo Command Center, and it will be immediately transferred to the Cricket and executed.
  • ...3 more annotations...
  • the Cricket's green LED light goes on while the Cricket is executing commands.
  • You can "launch" a procedure directly from the Cricket by pressing the white button on the Cricket.
  • You can send information from the Motor/Sensor Cricket back to the computer using the send instruction.
