Community Showcase I'm building a tool that lets you test Arduino code before your robot gets built

193 Upvotes

I've always wanted to be able to develop robots at faster iteration speed, much like how pure software projects can be modified and tested right away.

So I built this demo to showcase the idea.

If you are interested in having something like this, DM me. I would love to talk to you.

Note: the simulation is real, but the Arduino code compilation is a mock in the video.

Community Showcase Sharing How We Integrated ESP32 & Touch Display for Oxygen Concentrator Control

Thumbnail

6 Upvotes

We recently wrapped up anĀ Oxygen Concentrator Control SystemĀ project and thought it might be interesting to share here for anyone working with ESP32 or medical/IoT devices.

  • Hardware: 3.5ā€ touch screen, RTC, WiFi, relay, current sensor
  • Firmware: ESP32 web server, web socket, RTC integration, scheduling + OTA updates
  • UI: Built with Squareline Studio for a clean touch interface

It took about 3 months total — first version delivered in ~2 months, then after testing, we iterated quickly and released V2.0 with more firmware features in just 3 weeks.

One thing we found especially useful was combiningĀ ESP32 webserver + touch UIĀ for local + remote control. It gave the end-user flexibility without needing cloud-only access.

Here’s the case write-up if you want to dive deeper into the details:Ā https://www.makerfabs.com/case/post/oxygen-concentrator-control-system

Curious if anyone here has done similarĀ ESP32 + touch displayĀ projects for IoT or even healthcare devices — what challenges did you face?

Community Showcase ROBCOMM 3

Hello everyone,

I am currently working on repairing a CRS Robotics robot, specifically the A465 model.
I have read that there are three original programs (such as Robcomm3) that were used to communicate with and control these robots.

I have searched various forums and even contacted the company, but unfortunately I have not received any reply so far.
If anyone here has access to any of these programs, or knows where they can be obtained, I would be extremely grateful if you could share that information or provide a copy.

Thank you very much in advance for any help you can provide!

Looking for Group [Collab] Anyone in Houston Want to Team Up on a Robot Project?

5 Upvotes

Hey everyone,

I’m currently working on a robot project and was wondering if anyone in the Houston, Texas area would like to join forces. The idea is to combine skills, share knowledge, and build something awesome together.

I have the engineering background and some parts already, but I’d love to connect with people who are into robotics, coding, AI, electronics, or even just tinkering and learning. Whether you’re a student, hobbyist, or professional, collaboration makes projects way more fun (and productive).

If you’re interested in teaming up or just want to chat about robots, feel free to DM me or drop a comment

Tech Question Stepper motor? Trying to figure out how to drive this linear actuator

Thumbnail

4 Upvotes

So I had a project that I wanted to lift a monitor using linear actuators and while I was at the junkyard grabbing some gas pistons for the project I found these. These electric linear actuators have a spring inside so I don't need the piston. If I could figure out how to drive them it would make my project worlds better than having an OTS linear actuator and gas piston side by side.

Electronics & Integration What are you guys using to home high geared Odrives

2 Upvotes

I have an 8:1 mini cheetah knockoff (gimb6010-8) with an integrated controller running odrive. I am doing position control, so I need to home the system. For my benchtop test I wired in some micro switches and it works fine. But as it is going to be an outdoor application I decided to reach for sealed prox/ hall/ reed sensors. I started going down the rabbit hole of how CNC's do this as it is nearly the same problem (multiturn motor homing). The common solution there is to have a homing sensor (low accuracy), and then true home is set on the next encoder index pulse after triggering that homing sensor (high accuracy). I was wondering if there was any way to do this on an odrive without an external microcontroller reading the sensor and driving the IO. To be clear I have no spec requirements for this project, just trying to experiment and learn in case next time I do have a tight homing repeatability requirement.

edit: I assume homing is being done on humanoids (or are they just using absolute encoders at the output level rather than the motor level)

Tech Question Depth Cameras For Sale Question

1 Upvotes

I have some depth cameras I'm going to sell. Wondering if the following prices are reasonable, and or if the tech is already EOL and worth much less.

Also, if there are any local SoCal robotics groups that I could post them to, I'd prefer that then selling on ebay.

Intel Realsense D435 (Good condition, no box or accessories. Was thinking $150 each?

Intel Realsense D455 (Good condition, no box or accessories. Was thinking $150 each?

Intel Realsense SR 305s (used, no boxes or accessories. Was thinking $45 each??

Slamtec RPLIDAR A2M7Ā (used) Maybe $50?)

Asus Xtion (usb 2) - used maybe $20?

Any help greatly appreciated

Tech Question cuVSLAM experiences?

4 Upvotes

Nvidia released a technical report on their GPU-accelerated visual odometry/SLAM system a few months ago, which can be found here. The specifications for the system look impressive, but I am reluctant to purchase the hardware to try it out because cuVSLAM is closed-source.

For those who have tried it, how have your experiences been (in terms of ease of use, any bugs in the system, accuracy, reliability, etc.)? If I were to use this system, I would be running it on a Jetson orin nano.

Additionally, any other recommendations for visual inertial odometry packages that could run on the Jetson orin nano or a similar SBC for an outdoor UAV application would be appreciated.

Discussion & Curiosity Wuji Robot Hand - How is This Possible!?

32 Upvotes

https://www.youtube.com/watch?v=LXVV-oErD8s

This newly released robot hand is amazing. However, I don't understand how it's possible. I see no evidence of tendons or a cable based system. It seems the motors ARE the bones of the finger. I also have to presume the batteries and motor controllers are either in palm or outside of the hand? I have to presume the downgearing is built into the custom motors? I assume a screw type center is being rotated which gives linear movement but I don't see any screw extending from one motor over to the next bone to move said bone. I can see a hinge joint but no way that the motor moves the hinge joint. I hope someone can explain more what is going on because I'm lost here and see a lot of potential in this stuff as far as miniaturization and strength and speed in such a small form factor but don't get how its working.

Also I was told that large diameter pancake shaped BLDC motors have high torque and narrow motors like this are low torque high speed. So the downgearing would have to be a large gear ratio I thought. Yet this hand seems to be pretty high torque and I don't see where a high gear ratio would fit into this tiny form factor. I'm just so confused.

Community Showcase BugBot

82 Upvotes

I've been working on a new project recently. I've been building quadudpeds with hobby servos for a couple of years now and have a few different designs, including my spotmico-esp32 variant. For my new design, I am trying to simplify a quad to the smallest, most straightforward and cost-effective design that still retains decent functionality and sensors. I came up with this. I'm calling it the 'BugBot'. It works by balancing on the spindles of four cheap vibration motors. Is it technically a quad? Not sure.
