Hi! I want to build a robot like a learning process but I would like the robot to be able to lift a can of coke (330Ml) for my project. Which weighs about 350g. Do you have any ideas or link to what parts I should pick and etc? Thank you so much in advance for your help!

As cbenson mentioned in the shout you will need to be more specific. Do you want an arm that can reach out and lift it? How long do you want the arm? how far does it need to lift? how fast? Or maybe you want a rolling robot that rolls over the top of the can and lifts it eno…

Thanks for the reply. My plan is to have a mini fridge where I store coke, and then some how make the door open by some programming or if the robot arm is strong enough? Then I hope I can make the robot arm lift the coke out of the mini fridge and put it on conveyor belt and it w…

That is a pretty ambitious project, especially for a first robot. But it is doable. Building an arm from scratch is a large project, even for an experienced builder. An arm that can lift 350g fully extended is actually a pretty large arm for a hobby robot. This project can be…

Big results require big ambitions :wink: Thank you again! What robot arm / kit would you personally recommend? I dont have must experience though but I am willing to learn :slight_smile: Would also be nice to make him do the task with a simple click of a button from my computer. …

That’s a good attitude! I think it’s best if I let someone from robotshop make a recommdation. They will be much more familiar with the products. All I can do is read teh specs. @cbenson is a good person to ask if no one jumps in here.

The task of opening the fridge should not be done by the arm itself - there’s quite a seal around the door which makes it quite hard to open. Use a linear actuator mounted to the top to open it: https://www.robotshop.com/en/standard-actuators.html You might think about how you’…

If I say that I am on a budget on the arm. Is it possible to decrease the price on the arm, ca 200 - 300 ? Does the parts ever come on sale?

The arm is the expensive part - inexpensive arms simply don’t have the reach or the torque. The parts do occasionally come on sale, but cann’t say when / why. A $300 arm would be something like: https://www.robotshop.com/en/lynxmotion-al5d-4-degrees-of-freedom-robotic-arm-combo-…

I see might buy the 600$ one, if it someday comes for sale. Im not in a rush. Btw do you have any ideas how to make a convejor belt, or buy some cheap once. I need it to be thin and long

Cheapest way would not to have it motorized - use a “gravity chute”. Most of the production parts used for conveyors in hobby robotics are not meant to be very long and might break. The Lynxmotion one is robust, but would not be cheap if you need a long length: https://www.robot…
