Robot Servos/control board advice

Hi, I would like to do an investment and to buy some servos (10/20 units).

I don't have too much money to spend, so I'm looking for cheap servos with however enough torque to do some interesting robots (humanoid, arm, hexapod, etc).

Initially I found MG995/MG996R servos, then I found rds3115 robot servo.

The features of the rds3115 are:

Got all the parts... any tips before I start?

Hey all, so I have a simple idea for a robot, hack a hexbug spider and put a Sharp IR sensor on it to make it autonomous.


I have:

1 hexbug spider

1 Arduino UNO

1 Seeed Studio motor shield

1 Sharo IR sensor from the SH robot

all the hook ups, solder etc.


Heres my question; would it make more sense to hack the existing chip on the spider, or cut it out and just have everything go straight into the Arduino? 


If you have any tips or such before I get started, that would be really appreciated!

Mecanum Robot

In my blog about the Shanghai Maker Carnival i wrote about the workshop and our VIP guests but not much about the other stuff. here it goes, the other stuff. One of the interesting objects was the Mecanum Robot (well, actually remote controlled), a project of my colleague Angelo. He build that monster, improved, failed, improved again to make it work. You might imagine how much fun it was to test it in the office :-)

RC Robot Car wheels turn too slowly

I have just put together a basic rc robot car, based on an arduino uno, motor shield (as I fried the original circuit board trying to measure voltages :) and of course a basic rc car (new bright). I can get the car to turn its wheels left and right and get the wheels to go forwards and backwards (when in the air) however the forwards and backward wheel speed is lacklustre (analogwrite(11, 255)- to the point where if place it on then ground the wheels don't turn and the car doesn't move. If I connect the rear wheels to the battery directly (9v battery) the wheels turn ok.

Smart Doodle Bot: ES100 MC Group 3

Hi everyone!

We're wrinting this blog as part of a college project for our ES 100 Introduction to Engineering and Design Class.  This will be the first robot we have ever made.  The purpose of this project is to make a robot that can draw, make music, and dance.  

We're purchasing the "smart doodle bot" from Hobby King to get started.  We put our order in on September 8th.  Hopefully, it will come in soon because we could only purchase it from Hong Kong.

This Processing application is ment to simulate a differential wheeled robot, very used nowadays.     Read more

First robot idea

I'm new to this website, but have been researching robots for a while, and my ultimate aim is to have a cube shaped robot on 4 wheels which can walk around on its own, and can follow you, with a talking ability if that's possible, any help would be appreciated. Thanks, smiggle

JME Mantzel's robot kit on Kickstarter

Hi everybody!

Just have seen JME Mantzel's robot on Kickstarter. I think it is awesome! :) Here is a related video from his channel on Youtube. Also if you like it, spread the word, as what he's doing is absolutely brilliant! :) I'm totally gettting one to play with as it is hack friendly! :)

Hope this type of ad/spam is acceptable :) Actually I hope to see more great things to take off!

[SOLVED] Strange compilation error

Hi everybody!

I'm making a little robot using Arduino and it works fine (you can see how it works on the embedded video).

The robot walk alone perfectly but today I tried to use an infrared remote with an infrared receptor to use my robot like an RC car, and I had this error at compilation (I'm using IRremote library):


core.a(Tone.cpp.o): In function `__vector_7':

D:\Program Files\Arduino\hardware\arduino\cores\arduino/Tone.cpp:535: multiple definition of `__vector_7'

Base for paintball rc robot

Hi! This is my first blogpost here, so bare with me.

This will not be the first robot I build, even though I think it could be done by scavaging parts from different finished products. I'm thinking of building an rc paintball car with a camera on it for navigation. Would something like this be useable? http://www.hobbytron.com/HobbyEnginePremiumLabelConstructionCraneTruck11824GhzRTRRC.html#
