Dogs are often left at home alone for periods of time when their owner needs to leave the house. This can cause a dog to become anxious or bored, which can then lead to the dog acting out and chewing on the furniture or causing some other damage throughout the house. We want to develop a device that will entertain the dog with minimal interaction from the owner. Our device will utilize movement and sound to attract a dog’s attention. The device will be able to navigate throughout the house by using IR sensors on the vehicle in order to avoid obstacles. Most devices currently on the market require a higher level of user interaction, which we are trying to avoid with our product. Furthermore, our product has a durable design that is built for the rougher playing style of a dog while still able to avoid obstacles autonomously and operate when dropped in any orientation.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
