Although the exterior has been build minor modifications are still being made to place all component accordingly in the interior of the body. We have also been working on trouble shooting all the components and connecting all together. In working with electric components, specifications need to be read carefully to ensure that the correct voltage and amperage are given to …

Our biggest accomplishment for week 9 has been building the prototype body. This 2nd body is made of with a sturdier sheet metal that was water jet cut. We received a 2D flat plate cut to specification that was later bend and weld in some areas to give it its 3D body. There were some minor modifications needed to be …

In trying to incorporate all subsystems into one, we had a few glitches in our main controls. One of the main issue that arise in the integration was a non-responsive relay. The signal send by our touch screen was not going through to the relay, the solenoid nor the pump were actuating. Unfortunately, the delay function that was used for …

The controls subsystem has made great progress this week, the supplement page has been re-visualized and resize to include a next button and reset button. The next button concludes the selection of one or more than one supplement. A reset button, clears the page selection in case a wrong selection in the supplement page was made. We have also included …

Both our liquid and food subsystem and perform simultaneously. The final setting and code so that both can work together and dispense the appropriate amount of substance is still being worked on. This week the liquid subsystem used a new setup to pressurize the cartridge, an air solenoid valve was included inline with the air pump and the cartridge (syringe). …

For subsystem 2 the solenoid valve has been connected to the microcontroller and a transistor to change the state of the valve, the system is changing states; however, the air flow is not being released from the outputs, its believe that is due to the low airflow pressure. The reason for trying the solenoid is to regulate the amount of …

Motor can do partial rotation, it can be controlled to release in the step of a wedge which is equivalent to approximately an ounce of food. The motor has been successfully integrated with the power supply, we no longer have overheating issue and the motor is receiving the appropriate current and voltage. We will be using one power supply, it …

New electrical components were received to continue working on the subsystems. We meet with both the industry sponsor and adviser once so far to receive feedback on the prototype. Subsystem 1 received a new motor with a higher torque capability, holding torque is 1.9Nm. It can make full rotation currently dispensing more than the desired food quantity, but it will …

The stepper motor requires 12 Volts and 2 Amps, therefore it is critical that the power supply can output the 12V and 2Amp to avoid the motor drive from overheating. The adequate resistor is not yet found to regulate the amperage, but it is being worked on. No changes to subsystem 3 or Subsystem 4 in term of design or …

The focus for this week was to put together the system in the temporary housing. The housing manufactured is a very simplified version of our CAD model, this model is solely to demonstrate the location of each component and the overall functionality. The straps on the front will hold the food container in place, it’s a representation of the plastic …
