Trouble with servos!

I’m working on a robot that’s supposed to place dominoes in a track. As part of the design, there’s an arm that grabs and places the dominoes.

How do you do precision positioning

for a school project i'm making a robot that is connected via bluetooth to my pc and I need to have it's exact position and it has to be able to drive in a straight line.

Does anyone know what kind of sensor would be best to use and in what way it should be programmed??

The Mailman

 

Long time no see...

I just wanted to share with you something I worked on during the month of January. I particpated in a robot competition here at M.I.T called MASLAB. My robot and team ended up taking 1st place. The details can be found on my website.

I'm sorry that I don't have the time to write a proper robot post about it on LMR.

Dagu Robotic Arm 6DoF - Bacuri02 Project

I recently received my Dagu Robotic Arm 6 DOF with Arexx control board 32 servos.

My original project is to use an Arduino Mega to control the arm and then make a wifi connection joystick control.

As I have not received my Arduino Mega board, I started tinkering in Arexx control board that I received along with the robotic arm. Along with the kit also came with a CD ROM which I believed the program to be installed on the computer to control the arm.

New tutorial on how to make an Arduino robot

I posted this on the Facebook page, but thought I'd post it here as well.

I just finished writing an in-depth tutorial on how to make an Arduino-based robot. It's targeted towards beginners and should help someone completely new to robotics to build their first robot, but anyone making a robot with an Arduino will find it useful. Here's picture of the robot I make in the tutorial:

Robot related groups around St Louis MO

Howdy,

Recently I found out that there are a number of LMR members really close to where I'm at. These are the public robotics related groups around St Louis MO USA. (I'm not including the school based groups -like FIRST- as those are not truly open to the public.)

AI.Frame funding

I've got in contact with the people behind the AI.Frame robots and there are some quite interesting designs. We've got some kits to try them. Now AI.Frame is going the next step and want to collect some funds for a first batch production.

Robot vacuum cleaner, thoughts?

So I've build the tutorial robot and me and a friend want to do something more challenging. We've decided to re-use the parts of the tutorial robot and make a similar robot, this time with a vacuum cleaning goal. It's not the goal to make one for personal use or even a good working one, it's for a school project so if it moves around and vacuum cleans a little bit it's good enough.

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:
