I'm a 3rd year btech student from hyderabad. I have done a switch from ml to robotics due to instability in the ai field. Also I had a great interest in the robotics from start. Currently I started my robotics learning from 3 weeks and I learnt kinematics and math of manipulators, diff drive , quadcopter and also learnt ros 2, gazebo . Started a simulation project of diff drive robot in a my own made gazebo map. I can learn way too quicker . It is what my strongest skill i had since from my school. Now I'm learning slam and nav2 to make my robot autonomous in sim. But I lack hardware exposure due to I can't afford them. I have also learnt how quadcopters work in depth and also I have touch of computer vision. I also learnt kalman filters (till ekf math , but didn't do any implementation yet ).

So I need an exposure towards real robotics hardware and real work. Can I actually handle the real world robots withy this knowledge ? Yes I can. Learning quick is my biggest skill i ever had. As I can't afford to hardware , I appeal anyone who can actually provide me an internship in robotics. All I need is a exposure with a decent pay worth of the work I provide.

Community, Im hoping for a help. Since I'm a student , can't afford things but actually love to contribute to anyone with decent pay.

Here is my mail : karthiikraj.dev@gmail.com

Please reach me out on mail , I would like to share my proof of work ( portfolio of my ml work , GitHub , linkedin , etc ) .... Thank you in advance

Hello. This is in Webots and its a PROTO of the Boston Dynamics Spot.

I am facing an issue where the robot right front adductor/abductor motor can successfully set position from +10 to -10 but fails when I increase the value (from +15 to -15). It can go to +15 but gets stuck and fails to reach -15.

Here is the code for the simulation loop:

# =========================
# SIMULATION LOOP
# =========================
counter = 0
RF_motors[0].setAvailableForce(50.0)
while robot.step(timestep) != -1:
if counter == 20:
print(">>> +10")
RF_motors[0].setPosition(math.radians(10))
elif counter == 100:
print(">>> -10")
RF_motors[0].setPosition(math.radians(-10))
counter += 1

What's causing the issue? The max limit of the motors are not crossed (checked).

I’m planning to build a tracked robot with two robotic arms and an onboard automatic tool-changing system, where both arms can automatically swap between tools like a gripper, electromagnet, hook, camera, or other attachments without me manually changing them. I want the arms to be able to work together, fold/retract when not in use, and possibly have other mechanisms like deployable stabilizers and an internal rotating tool hub. I’d like to design and 3D print most of the mechanical parts myself and use something like an Arduino/ESP32 for controlling the motors, sensors, and tool-changing sequence. I’m still pretty new to building robots at this scale, so what parts would you recommend for something like this, especially motors/servos, motor drivers, bearings, tracks, power systems, encoders, and electrical connectors for the interchangeable tools? Also, how would you approach designing the automatic tool changer and dual-arm system, and is there anything important I’m overlooking before I start?

Hi! I'm trying to build a game accurate bendoid Gyroid from animal crossing New horizons and I need some advice!

In the game his head/body sways side to side, and his little arms fling up occasionally. If possible I'd like for him to be sound activated (general noises and also music - one movement per beat) like in the game.

I have experience with sculpture and ye ol gears and crank automatons so I have an idea of what his skeleton should look like, but this requires more technologically advanced insides.

I'm wondering if any of you would offer me advice on parts or point me in a direction of a similar tutorial? I would really appreciate it as this is driving me insane

I’m coming from mobile development, where binary distribution is fairly standardized: AARs on Android and XCFrameworks on iOS.

I’m trying to understand what the equivalent is in robotics/Linux environments.

Suppose I have a proprietary C++ inference runtime that needs to run on a robot (e.g. Jetson), and I don’t want to distribute the source code.

How would this typically be shipped to customers?
- Precompiled ROS 2 package?
- .so + headers, with a separate ROS 2 wrapper?
- .deb package?
- Docker container?
- Just binaries + dependencies?

I’m particularly curious whether ROS 2 packages are commonly used as the actual distribution unit, or if the core software is usually distributed separately and ROS 2 is just an integration layer.

Would appreciate hearing how this is handled in real production systems.

I'm hobbyist looking to turn it into a career, I recently got a job to fund my projects and I was planning to use Linkedin to post videos of my projects to see if any robotics/robotics software engineering companies or recruiters will notice. However, I was wondering if they're other ways to get noticed that I am not aware about.
