hello, i'm currently building a project for one of my engineering courses, and was thinking to make a robo-firefighter. the one stipulation for this project is that it can't use microcontrollers so i was looking for a little guidance on how to tackle that part of the project. i made a mini outline for what i thought the circuit could look like considering microcontrollers aren't allowed.

would this outline be the right direction to go in to make the robot? or am i missing something. grateful for any advice for this!

what would be the best sensor for specifically detecting humans within the work envelope of a manufacturing robot? I know you can use simple ultrasonic proxy sensors but I want to try to and be a bit more complex and choose a sensor which will specifically detect humans so that it will only shutdown if a person walks into its envelope. I also know there are such sensors as a c02 sensor or a mass spectrometer which can pick up humans, but would these be effective?

for reference this is for an assignment and general curiosity/interest in the topic

any advice or feedback is appreciated thank you

Heyo, we are two students from Germany who have been given the task of repairing and programming a Franka Emika research robot to introduce to the children. We would like to connect a tablet and set the robot so that it traces what we draw on the tablet in real time. Is this possible? And if so? How to write the program and upload it to the interface?

Does anybody know any website where i could buy robotic pieces or whatevere. im looking especially for these

1 only Arduino UNO R3 with USB cable 2 only Big Easy Driver motor controllers 2 only 12 volt 30 ohm 17HS3430 NEMA17 stepper motors 2 only NEMA17 stepper brackets 1 only 3m length GT2 6mm timing belt 2 only GT2-20 6mm timing pulleys with 5mm bore 3 only GT2 6mm toothless idler pulleys with 4mm bore 4 only GT2-20 6mm toothed idler pulleys with 4mm bore 6 only LM12UU linear bearings

Beginner question here, I've been building mobile robots now for a while and I'm looking for a way to include Large Action Models in my pipeline but I don't know where to start. Can anyone point me in the right direction regarding the subject?

Appreciate the help!!

So this is the trace connection for power and wiring between devices. This project started from needing a new computer, wanting to get into AI, love of all things RC and wanting to get something I can play with, be entertaining enough and be a show piece when or if I go to shows, which I plan on doing. I also didn't want to be walking around all the time, and needed something that could haul me and my son around if it came to it using a trailer or his wagon. This model will be about at least 120KG when build is finished based on the hardware integration. Model weight alone is 50KG and is suppose to be engine to a road train. I'll be building 4 carriages after with all having independent E-drive train so shouldn't get stuck, can maintain high speeds and can pull like an ox or a Toyota highlander that no one told should quit trying to go up that mountain side that it wants to turn into an small hill.

Yes I'll admit there is a lot going on but this is going to be a built system almost like a car engine, so many parts working together in a tight space, requiring disassembly depending on where the issue is. This project will have me soldering, cutting and making custom hardware and software to make all this work. Now I told you a little about what I am doing with this project, maybe you can assist me with what I am missing for getting a self driving , obsolete avoidance, self protecting 10 wheel rover, that can use on board computing power just like a real tank and then be a shill display piece at home when I feel like gaming or doing some actual work

This is phase one, getting the blueprints and figuring out the parts required to get all working successfully. I can't think of anything else that need been added / removing as I am a one man army so any recommendations are well.

I also still can't figure out which rover software if any out there I can use.

After doing some quick research on the subject:

- using rotary actuators instead of expensive linear actuators for cost-saving

- designing their own PMSM motors in-house

- Chinese manufacturing ecosystem makes it cheaper to produce parts

Using MIT's mini-cheetah design, Hand-winding each actuator can bring the price down to ~$80. But with 12 of those needed to make a quadrupedal robot, that brings the price to $960 for just the actuators themselves. Then you need to factor in the rest of the body, the main controller and processors, the main body, and LIDAR and other sensors. On top of that you would have to sell it for about 3 times the cost of the product to profit and grow the robotics company.

that's my ipad in there btw

Switched out the Xbox controller and laptop for a RC controller. Any advice on how to connect a Pixhawk to a Roboclaw 2x60 would be appreciated.

I am building a device to move a tool back and forth using an linear actuator. This is the actuator I had in mind (1000mm option).

The desired action is for the actuator to move back and forth along its entire length. This will be in a shop setup so I want the controller to be small. I only need two controls 1.) on/off and 2.) speed.

This is my very first attempt at something like this. I have no code or electronics experience but I am willing to learn. This feels pretty simple so I'm willing to learn. Please talk to me like an idiot lol

THANK YOU!

Hello /Robotics Community.

I have a peculiar question that may or may not be addressed here in this group and does not seem to be easily “googled”.

I work for a company in the US that uses small/medium sized industrial robots (6-Axis and SCARA).

What is the difference between an industrial robot with the tariff code 8428.70.00.00 and 8479.50.00.00?

8428.70.00.00 Seems to be Industrial robots that fall under “Other Lifting, handling, loading or unloading machinery”

8479.50.00.00 Seems to be Industrial robots that fall under “Machines and mechanical appliances having individual functions, not specified or included elsewhere…”

Does this mean the USE of the robot will determine the code?

If the robot will be loading/unloading a CNC machine for example, will it be a different code then a robot that is dispensing sealant on a glass window?

What if we do not yet have an end use defined for the robot, and we are just stocking if for future use?

Anybody have any experience or input on this?

Normally all games at the RoboCup are fully autonomous, but this is a small test game, where some of the robots are remotely controlled.

Greetings everyone, I want to make a robotic arm with 5 or 6 axes. I plan to use it for fruit picking, I want to add camera modules and detect the fruit that has reached sufficient ripeness, cut and collect it. On the software side, I aim to do all the controls (motors, software) with a Raspberry pi. Since I don't have any robot arm experience, I don't want to waste a lot of time on the mechanical parts of the robot and I don't want to get bored. Therefore, I want to make a ready-made open source robot arm and spend more time on the software part. I am open to suggestions that will meet these needs.

Requirements

-Can be 5 or 6 axis

-Can lift 150-200 gr in weight max will be enough.

-I want the movements of the arm to be smooth

-I expect the 50 cm arm to open so that it can reach the fruit

I am open to your robot arm recommendations that you can recommend for these requirements, I would be happy if it is budget friendly.

I can print with a 3d printer, if you say it is recommended for robustness. I don't think there will be any cracking or breakage as there will not be much load.

Thank you.

Hi everyone.

In the last year I build this hexapod from scratch.

It uses hiwonder servos that communicate via serial bus. They are a bit slow but they carry a decent torque.

For the moment, it is controlled with a raspberry pi4. Maybe in the future I upgrade to something more powerful. And the best part is: it runs on ROS2 and it is open source!

I am now looking for a partner to continue developing this robot. DM me if you are interested. There is no need for a lot of experience, just motivation and a few basics (nothing advanced as this is a learning project for myself as well). I am in the CET timezone.

Hi everyone,

so we have a KUKA KR210 robot at our works, as soon as we close the door of the controller, we get the emergency stop inoperative error.

This error goes away once the door is opened again, does anybody have any idea why? attaching a picture of the error.

Hello r/robotics, Ive loved robotics ever since I was a kid and always wanted to know how to start building and designing my own robots. As someone who did not grow up with a lot of money I mainly relied on my high school to learn robotics where I compted for two years in the FIRST robotics competition. Now I am studying Mechanical Engineering as an undergraduate in college. To have a minor in robotics I need to take 5 classes which are only offered in the spring semester and I would need to major in Electrical Engineering. I'm in my sophmore year going into my junior year and even If I wanted to take these classes for a minor in robotics I'm drowning in work for my major. I want to self-study over the summer during my free time. Was anyone in a similar situation, or does anyone have advice or recourses that coulf help? Thank you so much in advance!!

Created in fusions 360, laser cut and 3d printed, and powered by arduino. I am working on the complete humanoid, but this prototype came out cool enough to preserve as its own project even though I’ve since created a newer version.
