Parts and 212 Other resources needed 22 Operation 23 Interfacing with your robot 3 Troubleshooting Disclaimer The use of the Line Sensing System for Mobile Robots assumes a basic knowledge of electronics and basic circuit systems Although the system does not use any high voltage levels these principles are necessary for safe and successful operation and long lifetime ofthe system 1 Introduction The Line Sensor for Mobile Robots is a compact durable and simple to use line sensing system which is easily integrated with different types of robots The main features of the system are Durability TTL output for ease of integration LED noti cation system Operation in wide variety oftemperature ranges Operation in wide variety ofambient light Ease of mounting 2 Operation 21 Resources The design includes a line sensing system which included two light sensors which are interfaced with a 74HC14E Schmitt Trigger and output LEDS One sensing system included the following 1 2 TCRT 5000

SensnrinrMniiie Rnhnls Cnnne inn Wires 23 Interfacing the line sensing system with your robot The line sensor for mobile robots is easily interfaced with the existing robot designs The system uses a 5V DC power supply to be provided from customer s robot Other power sources should not be used because of the possible damage to components To connect a line sensor to your robot connect the left side wirewhite wire to the digital inputs on your robot system and the right wireorange wire to the other digital inputs of your robot system Perform this before you apply 5V DC supply to the system 5V DC power supply turns on the system immediately Use the green lead as your ground connection and the red lead as your 5 V DC connection After making all of the necessary connections and applying power to the system you are ready to use the line sensing system and win an IEEE robot competition The system is most effective when used in a distance range of 15 mm from the surface It is very important that the sensor does no touch the surface The sensor will work in a wide range of lighting conditions It performs successfully in a uorescent lighting found in any classroom The sensor performance improves in darker ambient conditions Summary of the system speci cations Value Units Power Supply 5 VDC Digital Output Levels High 223 VDC Low 0005 VDC Sensing Distance 15 mm 30 Trouble Shooting In case that the senor malfunctions follow the outlined steps when troubleshooting 1 Check the power supply Make sure you are providing 5V DC exactly Connecting the sensor to other voltage sources will cause the destruction of various internal components Replace the 74HC14E Schmitt Trigger lC Carefully remove the IC using an IC puller and replace it with a new one I In case that the troubleshooting steps do not fix the problem you will probably require a new line sensing system IEEEHardWareDesignNotesdoc TGC 93005 IEEE Hardware Design Contest Notes Below are notes in no particular order that are relevant to the design contest Current teams should consult last year s teams for pointers Current teams should serve as advisors for next year s teams Current teams can become graduate teams in next year s contest Current team members should submit Undergraduate Research Scholar URS grant applications in the fall Funds can be used for parts and travel to SECon Teams that get URS grants are required to participate in Undergraduate Research Day aka Undergraduate Research Symposium which occurs in April Travel funds may also be requested from Speed Student Council and UofL Student Government Association Individuals who spend their own money on the project cannot be reimbursed by the university Local competition to see who goes to SECon will occur in late March There may be enough funds to send more than one team but only one team can compete at SECon Teams should plan to demo their robots at Engineers Days Custom parts for robots can be built at Speed s Rapid Prototyping Center This works particularly well for the robot chassis Mr Tim Gornet tj gom01louisvilleedu asks that all rapid prototyping requests be submitted at the same time Mr Gornet will give tours of the Rapid Prototyping Center Mr Gornet says I believe we can help the students in giving them some design guidance that will assist them in building their solid models 7 eg minimum wall thickness feature size ribbing undercuts We would be glad to give them a tour at the start of the semester to highlight the capabilities of the Selective Laser Sintering SLS process and discuss how it is used in product development We can then set up some timeframes and deadlines for the groups to have their nal designs to us for construction This will allow us to pack all of the parts into a single build and best utilize the build volume With this technology we can pack parts 3 dimensionally into a build In the Fall 2005 ECE 599 Capstone Design class 4 teams of students are designing robotic power trains Current robot teams may work with these 599 teams or use the devices designed by the 599 teams in new robot designs If a student intends to use the IEEE Hardware Design Contest as a project for ECE 599 that student should plan to take ECE 599 in the fall rather than the spring Please see httpraisespdlouisvilleedusystomECE599CapstoneIEEEdoc on the 599 home page Fall enrollment has several advantages IEEE teams would get right into careful planning and documentation early in the fall By the end of the fall term they would have fully developed and documented designs they would presumably have URS funding established and they would have parts ordered At the end of the fall term these students would be given an X deferred grade When the project is completed in the spring the grade would be replaced with an appropriate grade for the course For students who want to do the IEEE Hardware Design Contest as a project for ECE 599 but want to take 599 in the spring other arrangements must be made These students should begin working on the project as early in the fall as possible They should plan to complete the first few documents required of 599 students even though they are not yet enrolled in ECE 599 Specifically here s what each student should do 0 Make sure that you have the prerequisites for ECE 599 by the end of the fall term The prerequisites are ECE 420 ECE 421 ECE 489

and 1 case is important Verbs is supposed to agree with their subjects Keep a watch for irregular verbs that have crope into our language Don t use no double negatives A writer mustn t shift your point of view Join clauses good like a conjunction should Don t write runon sentences you must punctuate carefully About sentence fragments Don t use commas which aren t necessary Its important to use apostrophe s right Don t abbrev Avoid cliches like the plague Placing a comma between subject and predicate is all wrong Parenthetical words however should be put inside commas Consult the dictionary frequently to avoid mispellings Always check to see if you words out Excerpted from Frode Jensen English Fun Stu quot Wordsmiths publication date unknown EffectsPedaldoc 011209 Project Concept Guitar Effects Pedal Studentgenerated project proposed by Evan Hudson Sponsor Dr Thomas G Cleaver General Description Most electric guitar players now use guitar effects pedals especially distortion pedals to create a more dynamic sound for their guitar playing The problem is between playing regular background music lead guitar and soloing there are a lot of different sounds a guitar player will need for the music to sound less monotonous We will be designing a pedal strictly for lead parts notes being played behind music as opposed to chords and for solos This will create the sustain and distortion that a guitar player needs without having to use other pedals combining them and turning knobs to get the perfect sound It should be as simple as turning it on and then playing the leadsolo Design Study These are the technical requirements of the pedal 0 For all pedals their must be an input and output buffer system using transistors o A foot switch to turn on the pedal 0 A bypass circuit for when the pedal is turned off so that it doesn t affect the sound coming through 0 Runs off of a 9v battery like factory made pedals 0 Volume knob for controlling level of sound sent to the amp 0 It plugs into one side of the guitar via a 183911 inch cable and out the other side of it into a guitar amp using the same type of cable Speci c expectations and deliverables 0 Research into how big or small the circuit inside can be before sound is delayed or affected in some other way 0 Have to find a way to get parts that are not necessarily associated with basic electronics like foot switch 183911 inch connections etc o Differentiating the sound enough from commercial pedals to be unique 0 It must be controlled enough that it will work with all types of guitars o It must be safe and reliable because there is not much room for error when playing on stage 0 It must be small convenience is a factor 0 Price must be low enough to compete with other guitar pedals though uniqueness is more important Participants Evan Hudson Jake Murphy and David Miller
