Grippy-Bot Grab the 3d printable STL files for the Grippy-Bot from Cult 3d - https://cults3d.com/en/3d-model/gadget/grippy-bot. This model is a free to download, and is pretty quick to 3d print. I used the Cura slicer with ‘Standard’ print settings and these worked out fine. I managed to print all the items on the build plate at the same time. Bill of Materials Part Description Qty Cost SG90 Servo These are the motors that move the parts of the arm 5 £4.00 Inventor 2040 W This is the brains of the Robot arm and will provide WiFi access. Available from Pimoroni 1 £34.50 You’ll probably find packs of Servos online cheaper than buying them individually. MicroPython Code This project enables you to control the robot arm over wifi, using the amazing Phew! library from Pimoroni. Phew provides simple functions for creating an Access Point, serving Webpages from the Pico W and a templating engine for embedding variables in those web pages. Download the code from here: https://www.github.com/kevinmcaleer/inventor_arm You’ll need to install Phew! on the Pico W, and copy over the index.html file too. You can upload files using Thonny (Right click on the files and folders to upload from the thonny files menu). If you want to know more about how to install Phew! Watch this part of this video There are two MicroPython programs in the repository: test01.py - A simple test program to check the motors are working - they will all move from their minimum to maximum values test02.py - This is the main program, it will display a web-based user interface on the IP address logged to the console. Just type that address into the web browser of any device, phone, table or computer on the same network to access the Robot Arm webpage. Overview of the code There are two parts to the robot arm code - the MicroPython that runs on the Inventor 2040 W, and the Javascript that runs on the browser, from the index.html file. MicroPython code The Wifi SSID and Password are defined in a config.py file on the Pico W - if this doesn’t exist you’ll need to create it with the following content: wifi_ssid = '<enter your WIFI name here>' wifi_password = '<enter your WIFI password here>' The first block of code brings in all the software libraries needed for this project, including the phew! library, and the Inventor 2040 W library. from phew import * from phew import connect_to_wifi, server, logging from phew import render_template from config import wifi_ssid, wifi_password from inventor import Inventor2040W, SERVO_1, SERVO_2, SERVO_3, SERVO_4, SERVO_5, SERVO_6 from time import sleep import math The next block of code connects to the wifi network, creates a board variable and sets each of the servos to its middle position. # Connect to WiFi ip = connect_to_wifi(wifi_ssid, wifi_password) # Create a new board board = Inventor2040W() # Set all servos to mid position for servo in board.servos: servo.to_mid() print(f'servo: {servo}, value {servo.value()}') sleep(0.1) We create a position function to take values passed to it from the webserver and sets the servos accordingly. def position(arm=None, wrist=None, elbow=None, finger=None, base=None): """ Set the servo positions """ if finger is not None: board.servos[SERVO_2].value(finger) if wrist is not None: board.servos[SERVO_3].value(wrist) if arm is not None: board.servos[SERVO_4].value(arm) if elbow is not None: board.servos[SERVO_5].value(elbow) if base is not None: board.servos[SERVO_6].value(base) sleep(0.01) The next block of code listens to any web requests to the / url and either send the rendered index.html file back to the users browser, or processes the servo slider positions, one for each of the servos. @server.route('/', methods=['GET','POST']) def index(request): if request.method == 'GET': return render_template('index.html') elif request.method == 'POST': elbow = request.form.get("elbow", None) arm = request.form.get("arm", None) base = request.form.get("base", None) finger = request.form.get("finger", None) wrist = request.form.get("wrist", None) if elbow is not None: position(elbow=int(elbow)) if arm is not None: position(arm=int(arm)) if base is not None: position(base=int(base)) if wrist is not None: position(wrist=int(wrist)) if finger is not None: position(finger=int(finger)) # Try without the line below to speed up the response return render_template('index.html') The last block of code shows the IP address of the Inventor 2040 W after it connected to wifi earlier, and then starts the Webserver. # Show the IP Address logging.info(f'IP: {ip}') logging.is_disabled = True # Start the server server.run() Javascript The other code we need runs on the users browser and is therefore written in Javascript: function post_values() { $.post( "", { elbow: elbow.value, base: base.value, arm: arm.value, wrist: wrist.value, finger: finger.value }, function(data) { } ); }; This code takes the values from each of the sliders and posts them to the webserver. It uses JQuery to simplify the code required to post values back to the webserver. Javascript can look a bit esoteric to the uninitiated - I’m not a massive fan of the language as its now obvious whats going on from the code itself, and it requires a firm understanding of the grammar and syntax to have the vaguest of clues as to what is going on. Wiring up the Servos to the Inventor 2040 W Wiring up the robot arm is pretty simple - just plug each of the servo connectors into the Inventor 2040 W using the connections as shown below: Servo Inventor 2040 Finger Servo 2 Wrist Servo 3 Arm Servo 4 Elbow Servo 5 Base Servo 6 The Web UI The Web UI has 5 sliders - one for each of the servos. The middle position corresponds to the Servos middle position. If you move the slider and then release the mouse button, the servo will then move to the position selected. The Pico Phew! library will find it difficult to move the servo in realtime sync with the slider - ask me how I know! Conclusion This is a great starter project to experiment with robotics. There are lots of area to improve upon this project including: stronger servos servo position feedback (requires a higher quality servo with feedback wiring) more robot 3d design longer arm for further reach double jointed servo claw to enable better and more precise handling of objects with the claw

Welcome to our channel! Before we dive into the detailed review of the RasTech Raspberry Pi 5 Kit with 16GB RAM, just a quick note: the link to purchase this product at a discounted price is pinned in the first comment, so be sure to check it out. This kit is a comprehensive package designed for both hobbyists and professionals who want to harness the power of the latest Raspberry Pi 5 board. Included in the kit is the Raspberry Pi 5 single board computer with a hefty 16GB of RAM, a robust 27W GaN power supply rated at 5.1V and 5A, four heat sinks to keep the system cool, and a screwdriver for easy assembly.
The Raspberry Pi 5 itself is a significant upgrade over its predecessor, featuring a Broadcom BCM2712 64-bit quad-core Arm Cortex-A76 processor clocked at 2.4GHz. This translates to roughly 2 to 3 times faster CPU performance compared to the Raspberry Pi 4, which is a major boost for multitasking, programming, and media applications. On the graphics side, the 800MHz VideoCore VII GPU supports OpenGL ES 3.1 and Vulkan 1.2, delivering enhanced graphical performance suitable for gaming, media streaming, and more.
