Let's Make Robots!

Yahmez I hear you know someone, who knows someone.. Well I just have a question..

So I hear you have a good source for faulhaber motors, and I'd like to hear which kind of motors you're able to supply and the cost + shipping cost to Denmark.. 



Robo-War--A call for ideas

We are having a robot war in our engineering institute, IIT Guwahati.

Need some ideas....the task is to push the opponent out of arena or immobilise it for atlest 30 seconds. Current limit-10amps, Weight limit-60kgs.


ROBOCALYPSE: WRECK OR BREAK AIM: The  objective  is to  make  a  wired/wireless,  manually controlled  bot that  can immobilize  the  opponent’s bot in  a  one  on  one  competition.

Too lazy to think for yourself?? Get in here and be inspired for your next more advanced robotic project!

The Subject Headline says it all..

Not really beginner ideas, I just wanted to share the link

100 robotics ideas:



 Also is there a way we could share all our pictures of mechanical design, robots, etc in a .rar file. come on.. admit it.. you've saved a lot of pictures from google over the years, why not share it for inspiration / knowledge. 


servos are not working

I have a spektrum dx5e transmitter and a ar610 reciever. I believe that they are paired because when I turn on the transmiter the recivers light turns on. However I lost the bind plug but I somehow managed to bind them. I pluged in my servos and batteries into the correct slots but noithing happens when I move the sticks. What am I doing wrong?

Lawnmower Project - Drive Motor recommendations

Hi All,

First post here, such a great forum!

To get right to it, I am looking at building an RC lawn mower. At this stage the plan is to just start with a 4 or 6 wheeled frame. Each wheel will be driven directly by a motor. Basically its a big, hella strong rover! It needs to be at least 4x4 because I will be mowing on a slope (not up and down the slope, but along it so traction is vital).

Need experienced users of Pyose/NUKE editor for Hexapod

ive built a Hexapod using MG90S digital servos and a Torobot 32 channel servo controller but I'm having trouble learning the IK. I ran across a program called PyPose\Nuke editor.

The easiest way to program my bot using that controller would be to write each action group seperate and download it so it will give me a Function to program the PS2 controller it comes with to wirelessly control it.

Dagu ComMotion Confusion

I purchased a Dagu Scamper to enter the OddBot art contest. Mechanical assemply completed without problems. Trying to get started with the software. Found the ComMotion instruction manual and a package called "ComMotion_Redboard_Demo" which contains four .ino files which compile and load into a Sparkfun redboard.

Help sequencing a hexapod ripple gait.

Im looking to see if any body can help me design a hexapod ripple gait sequence for a serial servo sequencing program? Ive looked around and can find several move lists where it tells you which legs move and in what order but not what the othet legs are supposed to do at the same time.

I would like to start from the beginning. First leg if you please.

Any help would be appreciated.

Monster moto shield + Arduino +Pololu 12V, 29:1 Gear Motor Encoder hardware problem

electronic enthusiasts!

I am trying to build a balancing robot with two wheels, using the polulu gear motor as mentioned above. In order to have a strong motor driver,the monster moto shield is used in this project. Here is the components and datasheets which is used.

Problem with PID controller


i'm making a line follower project and i was thinking to use PID controller, but i don't know how to calculate the kp,ki,kd ..!

and there's a little probleme, i don't know what's beter to use, digital or analog ir sensor in PIC16F877A ?

thanks .

need an idea for my graduation project

I am facing a challenge in finding an idea for my graduation project so plz if you can give me any idea for that , i am studying control engineering.

High friction material

I've not logged in for a while, but I'm still working on my robot, as and when I get the chance. I'll update my robot page, when I have the next part finished. The next part is the reason for this post, however. I appear to have hit a stumbling block and as usual, I'm turning to the good folk here at LMR, for advice.



first I am not englishman, I live in Slovak, thats sorry for my english

second...I am building a autonomous robot, I have 6WD wild thumper, T'Rex motor controller and arduino (UNO and MEGA and some sensors)

I want a car which will have a sensors to be autonomous, GPS, camera to recognize object and faces, microphone to recognize voice, robotic arm.
