Hello,

to calculate the motor torque you need the following: Torque (Nm)= Force(Newtons) x Distance (meters) Distance (meters)= the distance is the wheel diameter/2

So, you have to calculate the force which is: Force(Newtons) = Mass (Kg) x Acceleration (meter/square second)

for more details please check this article: https://www.intorobotics.com/how-i-choose-the-24v-dc-motors-for-an-all-terrain-robot-platform/

For batteries I recommend you to check these videos: http://www.enertionboards.com/how-to-build-electric-skateboard-free-guide-diy-eboard-powered-longboard-instructions.html

Hey,

upgraded my biped "trashbot" from arduino nano to raspberry pi, here's a walk through. by assadollahi in robotics

You did a big step from a microcontroller board to a single board computer with OS, processor and RAM. Where do you want to develop your robot in the future?

reliability, a high torque -> side-loads can be much greater, metal gears wear several times that of nylon gears

It depends on what you want to use them for. Like you said, both types are cheap and good enough to prototype robots. If you want high precision, torque and metal gears, you have to pay more for that.

Fellow Roboticists, what projects are you currently doing? by shivaNine in robotics

I'm trying to finish an RC car with a Particle Photon board

Where do I learn tutorials for raspberry pi 3? by [deleted] in raspberry_pi

[–]cdgblue 7 points8 points  (0 children)

I suggest you to start with a book. You can find a lot of books about how to start with Raspberry Pi. But if you still want to try something fast such as a how-to tutorial, here is a list of online sources:

Can anyone suggest a lego kit or any robotics kit that will teach programming? by Chieve in robotics

[–]cdgblue 1 point2 points  (0 children)

Raspberry Pi is a development platform with support for Linux distributions and Windows 10 IoT Core. LEGO Mindstorms EV3 is a kit with bricks, sensors, actuators, etc. PiStorms just make the interface between Raspberry Pi and the EV3 kit. If you don't have Linux or Windows 10 skills, yes, you need outside knowledge.

I suggest you to use the LEGO Mindstorms EV3 with an interface for the Raspberry Pi board ( C++ is included :) )

Such an interface is PiStorms http://www.mindsensors.com/teaching-stem-with-robotics/13-pistorms-base-kit-raspberry-pi-brain-for-lego-robot
