Mechanics and Construction / DC motor
« Last post by Nikesh Kumar on April 26, 2016, 08:08:16 AM »
Hello frnd..
I am Nikesh
Iam doing a project based on Agribot. In my project I have used four DC motors to run four wheels of my vehicle .
I have connected motor shaft directly to wear to minimize the losses.
My question is that i haven't used any gears.  so how far it is good and how much it is advantageous than geared system. the total weight is 5kg..  please reply me fast

My company buys and sells industrial surplus, including robotics. You may want to check out the website since stuff comes and goes every day.

What's the name of the company?

   I have compiled a list of books, websites and sources for parts, related to robotics and electronics, that I have found useful and interesting. Hopefully this will be useful to you if you are searching for parts or information.

This is nothing short of gold, thank you!!!

Mechanics and Construction / Re: CS student help needed in motor selection

there is some information in the tutorials section regarding calculating motor torque. search the posts and web as well.

a couple notes:
- what units is your speed in?
- you will probably need a gearbox (or some other speed reduction)
- what acceleration do you need?
- what surface is it driving over?
- does it need to go up any incline if so how steep?
- how much will the robot weigh (i'm assuming the weight provided is for the payload)?

Software / Segway/Robotics teacher
« Last post by Kadijs on April 23, 2016, 05:17:00 PM »

Hello.

So I`m new to electronics and robotics. But I want/need to build a segway. I already have bought all parts. But I don`t have enough knowledge to build one. The biggest problem is with code. I`m using arduino uno. So but I don`t have idea how to make this code. I`we looked on interned for codes but I don`t know what has to be changed and that stuff.

So I`m looking for a teacher who could help me to go trough all that. I`m willing to pay as well.

Thanks looking in to this.

My company sells used robotics. There may be something there that is useful for parts.

That's amazing! And, middle school kids. I thought our high school kids were amazing doing a competition battle robot. This is something useful with real-world application. Nice job.

Not sure if you are a young person looking for something really basic to get started, but I bought and donated some of these kits to a local high school for their robotics class to work on:
