![]() ![]() ![]() Take the other end, thread it around the pulley wheel on our stepper motor shaft and then bring it back to the paddle. Push this into the groove and this will hold it into place. We can now take one end of the teethed belt and thread this thought the horizontal slot on one end of the paddle, push it through, wrap it around the pin so that the teeth come together and lock in the middle. Ensure one of the grub screws is firmly attached to the flat side of the shaft.Īdd the cable for this motor and thread the other end down through the cable tidy. (Don't forget you can find a link to all the parts at the top of this guide). Take the pulley for the timing belt and attach to the shaft of the stepper motor for our X axis. The last image shows how your should look so far. You can fix this in place against the flat edge of the cable tidy with a screw through the hole in the last piece of the cable chain. Thread all the cable down through the hole and then curl the cable chain under itself back towards the cable tidy as shown in the images. You should be able to just push it into the hole - make sure that the flat edge is facing away from the paddle and chain we've been working with. Now we can print and add a guide tube into the hole we drilled to help smarten it up a bit. When inserting the paddle make sure the short side with the chain attached is facing the hole we just drilled. You need to do this carefully so as not to dislodge any of the balls from inside the bearings. Remove both rods from the right hand side of the barbot and thread them through the linear bearings. This is important so that the chain is not twisted in relation to where it exits the paddle. The centre of the hole needs to be 25mm back from the front rod. You'll need to make a hole through the table top about 16 mm wide halfway along the distance of the steel rods. List of items used in this project and where to find them (the links are Amazon affiliate links and financially support this channel at no cost to you)Īrduino Uno: Motor driver: Contact Switch: Linear Bearings: Stepper Motor: Timing Belt and Pulley (2m version): Timing Belt and Pulley (5m version): HM10 Bluetooth Module: (Also makes it easy to take into the garden or a friends place). Many others out there soon get very expensive and often requires mains electrics - this is cheaper by design and runs entirely on 8 AA batteries. The aim of this project was to create a bar robot that was low cost and easy for anyone to write their own programme for. This easy Arduino based project can be 3D printed and is a cool Arduino project for beginners. The app also has a "Make Drinks" feature that allows you to find all the drinks that contain the ingredients you want to have in them.Build yourself a low-cost easy to assemble bluetooth controllable robotic bartender using an Arduino Uno. Additionally, you can browse nearly 500 drink recipes in the "All Drinks" section, and add your favorite drinks to the "Favorite Drinks" list. ![]() You can also list the ingredients you want to buy by simply adding them to your “Bar Cart.”īartender also offers a "My Drinks" section that highlights the drinks you can make based on the ingredients in your bar. The app has several features that make it stand out, such as "My Bar," which lists the ingredients in your bar and helps you determine which drinks you can make. With nearly 500 hand-verified recipes, this Android app allows you to input the ingredients you have, and it takes care of the rest by providing you with simple steps on how to create delicious drinks. Bartender is an all-in-one home bartending app designed to provide you with a simple and easy way to manage the ingredients you have in your home bar. ![]()
