Este proyecto está siendo desarrollado por alumnos del Tecnológico de Monterrey Campus Guadalajara, el cual está orientado para servir como un tipo de terapia para personas discapacitadas. El proyecto en sí consiste en el control de un vehículo de juguete por medio de pulsaciones que serán realizadas con pelotas anti-estrés, de esta forma la persona podrá realizar un ejercicio de fortalecimiento en sus extremidades superiores de una forma más entretenida y menos tediosa que las clásicas terapias. Es importante mencionar que para poder realizar este proyecto es necesario el uso de dos tarjetas Freedom KL25Z de Freescale®, dos módulos Bluetooth®, dos servomotores de rotación continua y dos sensores de presión, los cuales serán incorporados dentro de las pelotas anti-estrés. El vehículo de juguete estará compuesto por los servomotores, que servirán como llantas; un módulo Bluetooth®, el cual recibirá las señales del otro módulo; y una de las tarjetas Freedom KL25Z. Por otro lado una de las tarjetas Freedom KL25Z estará conectada con los sensores integrados en las pelotas anti-estrés y a un módulo cuya función es mandar la información capturada por los sensores al vehículo de juguete. La mecánica del proyecto depende de la pelota que sea presionada, pues si se presiona solamente una pelota, el vehículo avanzará, por otro lado si se presiona la otra pelota, el vehículo girará sobre su propio eje. Este proyecto tiene como fin la implementación de conocimiento prácticos y teóricos en busca de una aportación en beneficio de la sociedad. También es relevante comentar que las visiones a futuro de este proyecto es que pueda ser implementado como una especie de control para una silla de ruedas, con el fin de facilitar la movilidad y aumentar la comodidad al momento de usar este tipo de vehículo.

A peek at where vehicle technology is headed.

Este video faz um resumo do trabalho da Equipe LAB_TELECOM, da Faculdade de Tecnologia da Unicamp. Ficamos em 5º Lugar.

On this page you will find additional notes to chassis assembly you may find useful. Examples of components used are obtained from the http://www.soselectronic.com/ distributor. Cables To connect battery you will need cable shown at the image top right. You can use the cable provided with the car and add an appropriate connector to its end. This usually requires special crimping tool, so it may be more appropriate to buy the "Tamyia charging cable" (shown on the bottom left side of the image above), cut the banana ends and attach the connector to the board. If you search for the appropriate type of the connector, it is called usually Tamiya charging connector, Tamiya jack 6,3 mm (SOS code 70479) or similar. Another cable you have to assemble is a power supply cable for the microprocessor board. You will need approx. 10-15 cm long cable with the barrel jack (SOS code 3834) or similar on one end and 2-pin 2.54mm connector (e.g. SOS code 4934 + 4937) on the other end. NOTE: Never power the microprocessor board and interface boards from different power supplies! In such case the grounds on both boards are not connected and you can damage the board. The grey flat ribbon cable that interconnects the boards is for signals only, there is no common GND connection! Battery You may find (as we did) the provided cable strips too weak to hold the battery on the place. Replace them with the classic electricians cable strips (e.g. SOS code 67504). Also do not forget that the batteries need to be charged fully the first time you charge them or they will not be able to fully charge in the future. If you jump the gun because you want to test your code as soon as you can you will hurt yourself later as we found our battery was absolutely shot in later stages of our build. Motor wires To attach the motor to the interface board you may find (as we did) the cables too short. Then remove 6 screws on the bottom (see image on the left), open the motor box and desolder the short wires. Replace with approx. 15 cm long silicon cables at least 1mm2. End of the cables should be connected to the 3-pin connectors with the 3,9mm pitch (e.g. SOS order code 5914 ) - see image on the right. Again, the contacts should be attached using a special crimp tool. Camera To attach the camera we found useful to prepare two metal L-shaped pieces made from aluminium. With the help of black plastic distance posts (already available in the kit) and these metal stands, you may freely change the position of the camera over the surface. You may use following files to cut the required shapes (drawing was made using the QCad program): Preview (.pdf) CAD file (.dxf)   Base board There was no motherboard in the kit, so you will need to provide your own. To make life easier, we offer you our CAD files created with QCad program. You may use it to produce your board. We use plexiglass for ours, but any other plastic material is appropriate. The large hole in the middle is for cables from the servo. We attach the board to the car using the plastic standoffs (you will need them 55 mm long, so in our case, we used the combination of 40 + 15 mm) - see an example (SOS code 10260). To attach both the processor and interface boards the simillar 5mm plastic standoffs were used. Preview (.pdf) CAD file (.dxf) Getting all together Please, notice the orientation of cables, especially the power supplies. You may find useful following connection diagram. Enlarged Schematic (.png) NOTE: Never power the microprocessor board and interface boards from different power supplies! In such case the grounds on both boards are not connected and you can damage the board. The grey flat ribbon cable that interconnects the boards is for signals only, there is no common GND connection! Servo Motor connectors The parts provided are extremely flimsy and if you snap them in and the wheels are not perfectly straight the wheels will align wrong when the servo first turns on. First off just concentrate on one wheel at a time and we found it useful to have one person hold the wheel straight while the arm was in the proper position and then we used needle nose pliers to quickly and precisely snap the pieces into the wheel. Don't be afraid to use some muscle we hesitated a few times at first because it didn't look good but it was fine.

What you need to design Your job will be to connect the various components together, refine and add to the code we have provided and create a working intelligent car. Start thinking about how you will determine where the line is on the track, what algorithm you will use for steering and deciding how much power you want to send to your motor. You may want to read up on PID controllers, or other types of control systems. Are there any special features that you might want to add to your car – such as real time debugging? Those features will require extra work and up front planning. Planning and Teamwork You might not have the time to document all your designs and concepts properly before sitting down to code or to create a piece of hardware, but you might want to create an ordered list of all the different tasks which will be necessary to finish the car, who will do those items, and when you want each task to be finished. A schedule will help you determine if you are on track with your goals …
