Follow the instructions on the Setup tab to install viam-server on your Raspberry Pi and connect to your robot. After you get the first screw in and the servo gear looks good, start on the second screw. Apply pressure to the first screw so that the servo gear gets as far away from the mounted claw gear as possible. The reason for this is because if you screw the servo on too close, the two gears will be too tight, not allowing the claw to open and close. Attach the printed mount and claw end cap to the claw, add the previously removed screws and tighten.

Represented in that file are obstacles for the prize drop hole, and each of the four walls based on measurements we took from our enclosure.

These obstacle representations are defined in a JSON. You can find the file we used in our claw game repository. Mechanical claws are often used for gripping/clamping items in manufacturing environments. The two most common types of claws and clamps used are mechanical and hydraulic. Hydraulic clamping/gripping systems are best suited to high volume applications and to applications where critical tolerances must be maintained. Using electric pumps and digital pressure switches, hydraulic claws provide around 1% accuracy in clamping force. This script provides an interface to run a single move command, or to run move commands in sequences. However, for general purposes, grippers can be divided into 5 or 6main types, with each type being distinguished by the methods used to power and/or control the gripper itself. Press the buttons to execute the control commands defined in main.ts and watch your robot arm move around using the simple user interface.

We tested with different Viam swag items such as t-shirts and hats, but found that foam balls worked the best for us. Add the sides and fill the enclosure with prizes The main() function initializes different resources and then handles command line arguments to move the arm in a sequence for testing and debugging: async def main():This picture was taken at an angle behind the robotic claw. At the top, you can see the robotic claw's mounting plates. To the right of the servo, protruding from the other side of the robotic claw, you can see the golden servo gear. You want that gear to be parallel with the robotic claw. For example, here is the grab() function that calls the setGPIO() method. // Global variable: GPIO pin used for claw relay on the board With the addition of a simple servo motor and a little bit of code, the robotic claw can bring life to any project. Using just gears and the servo, gripping, grabbing and even clamping objects can be easily implemented into your project, be it a robot or a claw game. Setup is easy - as you'll soon find out. On the Raw JSON tab, replace the configuration with the following JSON configuration for your arm and gripper: { Now that the arm is set up and you have a CLI script you can use for testing - try testing the motion and claw grab with different items.
