| **Item Retrieval Robotic Assistant** Team Members: - Peng Chen (pengc5) - Haotian Wang (hw46) - Ziyi Han (ziyihan2) ## Problem Statement: When someone with a leg injury or mobility issues needs to retrieve items from another room at home, it can be quite inconvenient. Without assistance from others, they often need to rely on crutches or wheelchairs to reach the location of the item and pick it up, then return. While this may seem like a simple task, for those with limited mobility it can be very exhausting and inconvenient. Therefore, having a device that can help these individuals retrieve and deliver items they need would make their lives much easier. ## Solution: Our project is a remote-controlled car equipped with a robotic arm, designed to enable people to retrieve objects without the need to move. Users can operate the movement of the car and the robotic arm using joysticks on the controller. The remote controller features a screen that displays the camera feed from the robotic arm, allowing users to see the car’s surroundings and select items they want to pick up. After the robotic arm picks up an item, it will flip backwards and put the item into the box on the car. In addition, for items stored at heights, users can utilize the telescopic function of the robotic arm to reach the item. Moreover, by rotating the gripper of the robotic arm, users can open cabinets and drawers to retrieve items inside. ## Materials: Custom designed PCB , Microcontroller, Robotic arm, Grippers, Motor Drivers, Cameras, Joysticks, LCD Screen , Batteries , Car ## Subsystem 1- camera Camera will allow the user to see the condition around the robotic arm car, and the information which is collected by the camera will be transmitted to the monitor. Camera module will be a separate part with PCB since it is not used to control the car or robotic arm. ## Subsystem 2 - power The power of our project will be provided by the battery. The power will be separated into two parts: mechanical power supply and electronic power supply, and these two components are supplied with different powers by the battery. Mechanical power supply includes the power supply for electric motors of the car and robotic arm, and electronic power supply includes the power supply for PCB and so on. ## Subsystem 3 - remote controller Remote controller is used to remotely control the motion of the car and the rotation of the robotic arm. Remote controller will have one PCB which contains the signal generator, and the signal generator will send different signals to the robotic arm car, which could make the robotic arm car do different actions. ## Subsystem 4 - remote control car Remote control car is a car which could be remotely controlled by the remote controller to move forward and backward, turn left and turn right. The remote car contains electric motors, PCB and car itself like wheels. When the signal receiver in PCB receives the signal from the remote controller, the PCB will send the signal to control which wheels, which direction and what speed should turn. ## Subsystem 5 - remote control robotic arm Remote control robotic arm is the robotic arm installed on the remote control car. The remote control robotic arm will have two joints and one robotic hand, which make it flexible enough, and the motion of two joints and the robotic hand is finished by the electric motors. Also there will be PCB inside the remote control robotic arm, and PCB containing signal receiver which could receive signal from the remote controller could make the robotic arm finish different actions. ## Criterion For Success - Functionality and Accuracy: the robotic arm must be able to successfully pick up and place items weighing up to 2 kilograms into the box on the car in 95% of trails - Telescopic Reach: the telescopic function of the robotic arm should be able to extend to a minimum of 1.2m and successfully retrieve items placed at this height in 90% of trails - Gripper Effectiveness:The gripper must be capable of rotating and successfully opening cabinets or drawers in 90% of trails. |
