New to LMR and looking to get the most out of it? Check out the "Get the most out of LMR" page.
This Start Here section includes robots and projects which are designed to help beginners get started in robotics. If you'd like to submit an idea for a new project to add to this page, we invite you to contact us and we'd be happy to take a look.
The DFRobotShop Rover V2 – Arduino Compatible Tracked Robot (Basic Kit) is a versatile mobile robot tank based on the popular Arduino Uno USB Microcontroller Rev 3 microcontroller. The rover uses a twin motor gearbox and the Tamiya track and wheel set. The PCB incorporates a standard Arduino Uno, L293B motor driver, voltage regulator and prototyping area. The onboard voltage regulator allows the entire board to be powered using as little as 3.7V to ~9V.

This is the original “LMR Start Here” project. Although there are other “How to get started building robots” out there, this one focuses on getting you around everything extremely fast. You need no knowledge of … anything, and you will learn everything. This is a bit more “do it yourself”
OK, first off a disclaimer–i was a sociology major in college and the closest thing i have to engineering or STEM experience is my dad was an electrical engineer and i know how to program a vcr.
that said, my 8 year old has been showing a slight interest in robotics, programming, and snap circuits kits (those toys for kids that introduce electrical circuits to them). our mint robotic floor cleaner died and so i opened it up to try to strip it for parts.
1. is there anything worthwhile we can do with these parts?
2. i think the motor, which was what i was mainly shooting for, is in this plastic compartment attached to the wheels. i, for the life of me, can’t get these compartments open to access the motor. there are no visible screws and when i try to pry the edges off to see if a panel will lift off, it doesn’t budge. any ideas? i can post photos if that would be helpful. thanks so much!
The Mint motor is not the easiest to remove. You see the wheel cap with squares on the side? It needs to be turned slightly in order to be unlocked to get to the wheel. It can be turned by hand in some cases but, it is best done with a tool. What we did is printed squares of lexan and assembled them on a small base. We then insert the lexan squares into the wheel cover and turn it to unlock it.
why would people give you there parts they might need them but you can get one, for five dollars or 4 for 20 dollars online ebay only. Everywhere else is like 30 buck which is bs so by them on ebay but most take a month from china find one in usa if you can on ebay look it up. from with in usa will take like one week!
techset on youtube! well the sensors that detect the obstical ir or ping maybe those can be reused and the motors like you said can be glued onto a chassis for a new robot project. and main curcuit board can be sold online for like 40- 50 depending on the model of romba or irobot you have.
This is an old video, before the frame was even painted yellow. You can hear my wife chuckling as she sees the thing work successfully. She probably had her doubts that it ever would!

I have always dreamed of building my own robot but I can’t but with the help of this I will be able to make a robot
3WD Omni wheeled robot - Ultrasonic or RS485 issues
Just wondering if anyone has had any issues receiving usable data from an RS485 daisy-chained sonar setup. My group and I are using 3 sonar sensors linked by RS485 which came prebuilt as a robot kit from robotshop.
We have tried each one individually and they all work and give accurate data but, as soon as we link them in the suggested way(daisy chain) and start up the provided code, they give a single set of data that is not specific to any one sensor and can be affected by any of them; making it difficult to code object avoidance.
I haven’t found much documentation on this issue, however, we have tried many different wiring/jumper setups and code to set a master sensor with 2 slave sensors however accessing individual sensors for their data has been problematic.
Does anyone have any pertinent documentation or resources that we may have missed?
