I want to create a robot which uses solar power to charge phones.!!GREEN ENERGY!!

@aditya You can buy those fairly easily from many places. You don’t need to design and build an entire robot - it’s essentially a solar panel, regulator, charging circuit and battery.

I want to know that how make a robot need my home services & help my family members

@Soumyaranjan Pradhan That takes a lot of learning - either on your own or a formal education. We can’t quickly describe exactly what to do.

i would like to learn how to build robots

@IAN You’re at the right place!

@Allu Aryan You might try to make new friends through common interests (and of course school). If you’re interested in robotics, consider joining the RobotShop community.

i want to make a robot that can pick and carry objects of minimum 1 or 2 kg or higher weight from one place to other so that i can use it to carry objects from one placeto another like a asistant it should be controlled by remote or mobile or laptop also it should have wheels 2 or 4 and size greater than 3 feet. similar to a mobile manipulator or a 4 wd vehicle that has one or two robotic arms with grippers and strong servo motors. it should run for atleast 30 min to 2 hour… hope you will guide me and tell its full process or provide link to such project please help

I like watching different construction robots tutorials. Now it’s time to built my own first robot.

I’m working on a small autonomous car using a Line-Tracking Module ( Line-Tracking Module – Easyelecmodule ) with TCRT5000 sensors, and I’m running into an issue where the robot consistently loses the line when making sharper turns. The module seems to pick up the black line fine on straight paths, but the outer sensors don’t respond quickly enough during curves.

I’ve already adjusted the potentiometers for sensitivity and made sure the sensors are around 5–8 mm off the surface. The surface is matte and consistent, so reflection shouldn’t be the problem. Could it be that my power supply noise or signal delay between channels is throwing off detection timing? Or do I just need a multi-channel module (like five sensors instead of three) for smoother correction?

Any tips for tuning these sensors for tighter path tracking would be appreciated.
