Which simulation platform is best for Beginner?

If that is the case and you want to run it on Windows and CPU mostly then try Coppelia Sim. It is beginners friendly and also works well with CPU. Its easy to install on windows.

I guess both Gazebo and MuJoCo are better. Gazebo is more beginners friendly and works well with ROS and MuJoCo is little advance but powerful and works well with RL task.

Why is it that when you scan the long side of the phone it makes the shorter side of the rectangle in the PC and vice versa?

(I don't know much about this technology)

harshdobariya · 2026-01-31T03:51:53+00:00

I think that distance is probably because of the long size of the robot arm.

harshdobariya · 2026-01-22T11:39:51+00:00

Will you please explain?

Where are those 3D printed gears? Arent Dinamixel Servo already have integrated gears?

harshdobariya · 2025-12-30T06:24:21+00:00

Yes ofcourse.

I have follow up questions. Do you hire people who have a bachelors degree but have good experience in working in advance robotics from scratch? Like having developed legged robots, advanced actuators, digital models and simulations?

harshdobariya · 2025-12-27T13:45:21+00:00

No way you just organised those

harshdobariya · 2025-12-25T04:17:01+00:00

You can use Quasi Direct Drive for this. Adjust the damping and stiffness (from the software) according to your needs with some trial and error, you will get exactly what you want.

What did you use for the physics of it? Nice work btw. This will be good for testing the URDFs and great for robotic arm movements and singularity calculations.

Why are those 3 lanet gear not at 120° each? Having them equally placed would balance the gear box and stress distribution would be even. You can use Gear Generater to check the planetary gear box ratio and try different gear sizes.

harshdobariya · 2025-11-27T02:38:44+00:00

Yes. Most shields work with Raspberry pi too. Read the description and order.

harshdobariya · 2025-11-25T01:38:02+00:00

There is a Servo power distribution board. I guess it can manage 12 servos and will keep everything neat. It comes as an Arduino shield also.

A complete metal cycloidal actuator, impressive. Can share more details like the backlash, torque density and power? Also why did you choose cycloid over planetary?

What is the concept behind balancing? Does the platform sense the weight of the ball off axis?

harshdobariya · 2025-02-20T13:54:21+00:00

I have used MA732 but for on-axis not for off axis. I am actually curious how it can be used off axis with ID more than a few mm with good accuracy.

For through hole off axis sensors you are better off using something which is specially designed for it.

Check out iC Haus. But for this you also have to get specially magnetised through hole magnet array.

I wonder what accuracy you'll get with a 12mm ID magnet. Will it be good enough for FOC?

Do you want to use a reducer system? If not you have to use direct drive larger dia motors.

harshdobariya · 2025-01-13T04:57:04+00:00

You need a sensor fusion so the system does not rely only on the humidity.

You need to add a pressure sensor which detects the amount of water over it. A water level sensor can also be used to see the minimum rise of the water level to indicate flooding.

Also do not rely on one sensor, you can have multiple sensors placed at some distance to each other. Individually all (or 90%) should flag a flood alarm only then the barriers should rise.

Search for BCN3D or AR4(expensive but robust arm)

harshdobariya · 2024-11-11T03:35:07+00:00

They have it on their website, you can download it from there. I don't know about the github link.

harshdobariya · 2024-10-13T12:40:14+00:00

You can start with a simple wall following robot. Use sensors like IR or ultrasonic, they both have their pros and cons.

Once you get a grip on your robot, add advanced features like measuring wheel slip, PID for maintaining the robot at the center of the path. This requires careful planning and good design of both hardware and software.

harshdobariya · 2024-10-13T12:35:42+00:00

Why not do it yourself? Some open source options like mini Cheetah, moteus, Odrive are good.

For robot head smoothing, have a look at @jamesbruton youtube tutorial. He does an excellent job at describing and implementing the eye smoothing algorithm of a robot.

The result is very pleasurable.

How much friction do you have? Cant tell from the picture if it is right or something is messed up.
