Robotten the Bug
Robotten »The Bug« er et skoleprojekt hvor man skulle fremstille og programmere en selvkørende robot i det tværfalige projekt TVP4E på IHK i 2007 og det blev gennemført af Nicki Svendsen, Emil Hansen og jeg, som var gruppe gennem hele studiet. The Bug benytter magnetiske sensore til at følge en bane på gulvet optegnet med alu-folie og udføre forskellige handlinger ved tjekpunkter langs banen. Her er et par billede af The Bug under nogle af dens udviklingstrin igennem projektet.
Her ses et overblik af chassiset og et statediagram for den obligatoriske bane robotten skulle gennemføre som kan ses i videoklippet nedenunder.
Vi lavede også et kontrolcenter i Java til at styre robotten med bluetooth. Faktisk lavede vi også en app som i hvert fald virkede på min Sony Ericsson telefon og som også kunne styre robotten.
Specs & Lir
- The robot is able to follow a track of metallic tape on the floor by use of magnetic sensors.
- The motors are controlled by a special implementation of a PPI-controller.
- The overall control unit is an ATmega32 microcontroller unit programmed in the language C.
- The chassis is custom made from 5 mm transparent acrylic glass.
- The robot is communicable via bluetooth and can be controlled by a computer with a custom software program which also receives status information from the robot.
- Furthermore the robot can also be controlled from a mobile bluetooth enabled device such as a cell phone or PDA. Both programs will also draw a crudde layout of the track ritten by the robot from a relative origin. Both programs are written in the Java language.
- The robot is equipped with two blue LEDs for visual indication of the robot position in low light areas. The robot is also equipped with a buzzer which sounds if the robot should reach an error state.
- All PCBs and fittings on the robot are made by us: Nicki, Emil, and Christian. This is with the exception of the DC-motorene which are from Faulhaber and the wheels where bought from the hobby store Holte Modelhobby (Danish). Also we didn't make Santa Claus!
- The Bug assisted us in 3x grade 12 (A+) in the TVP4E course at IHK :)

It's filmed by Nicki and shows the robot completing the compulsory task as demanded by the specifications. It's Emil starting The Bug.
