Title: Butter Passing Robot


We want to make a butter passing robot, which can find the butter on the table and bring it back to a certain location. The robot will be able to move on its own, avoid other obstacles, and find the butter on the table.

We believe our project is appropriate for ECE 445 because it utilizes many aspects of knowledge we acquired here. For the hardware platform, we intend to build a vehicle similar to the one from ECE 110. It will have two motors(eg. ROB-11696), a thermal sensor(eg. SEN-10988) to detect motor temperature, an infrared sensor to detect irrelevant(non-butter) obstacles, a microcontroller(eg. ATmega328) to take all the sensors reading and output PWM signal accordingly to drive the motor. We intend to place all these circuits onto a PCB.

Aside from these sensors, we also intend to place a camera module(eg. OV7725) and a wireless module(eg. ESP8266) on our vehicle. The camera will take pictures of the environment the robot faces. And the pictures will get transferred via WiFi to a laptop, where we intend to run some python scripts to detect butter in the photo. We realize the time complexity of the code is crucial. However, since our target has a relatively distinct color and relatively fixed size, we think it’s possible to simplify the recognition process.

If we have enough time, we plan to implement basic speech recognition as add-on functions. The basic function would be for the robot to start operating once it hears a finger snap. We can use an audio sensor and some code on the microcontroller to realize that. For further improvements, we found some existing Arduino Modules that can recognize a fixed set of voice commands. With that, we can make the robot operate only under certain commands.

We found two similar projects by searching “Butter Passing Robot” on Google. The main advantage our project will have is the lower cost. Both these projects were built on existing robotic platform, which cost $70 and $170 respectively. Since we intend to build our hardware platform ourselves and focus on the core functionality of “passing butter”, our project will cost considerably less than the existing ones.

Cypress Robot Kit

Featured Project

Cypress is looking to develop a robotic kit with the purpose of interesting the maker community in the PSOC and its potential. We will be developing a shield that will attach to a PSoC board that will interface to our motors and sensors. To make the shield, we will design our own PCB that will mount on the PSoC directly. The end product will be a remote controlled rover-like robot (through bluetooth) with sensors to achieve line following and obstacle avoidance.

The modules that we will implement:

- Motor Control: H-bridge and PWM control

- Bluetooth Control: Serial communication with PSoC BLE Module, and phone application

- Line Following System: IR sensors

- Obstacle Avoidance System: Ultrasonic sensor

Cypress wishes to use as many off-the-shelf products as possible in order to achieve a “kit-able” design for hobbyists. Building the robot will be a plug-and-play experience so that users can focus on exploring the capabilities of the PSoC.

Our robot will offer three modes which can be toggled through the app: a line following mode, an obstacle-avoiding mode, and a manual-control mode. In the manual-control mode, one will be able to control the motors with the app. In autonomous modes, the robot will be controlled based off of the input from the sensors.
