Advice on building a pan/tilt robot arm

 

Hello LMR folks,

I am in need of some advice over a robot project I plan to build. I have a small amount of experience with using an Arduino, soldering and general circuit making, but I've never used motors yet.

What I plan to do is to have a "robot arm" attached to the ceiling with a camera at the end of it. The arm need to be able to rotate the camera around and depending on some conditions tilt it at different angles.

Heat Tracking Robot Arm/Head

Ok, I have been wondering if it would be possibly to build a robot head or arm that tracks thermal energy. You know how there are special thermal cameras that show areas of higher temperatures in different colors? I'm guessing those are pretty expensive, so would there be a simpler and cheaper way of building a thermal sensor? I was thinking of PIR sensors, but they can't really sense how hot something is, just if what its looking at is hotter than average.

Hey, This is a project I did over the summer. I made a robotic arm that is contolled with a 1:1 controller. The robotic arm is basically 4 standard servos and … Read more

Incredible wooden mechanical machines video

Have a look at the engineering that has gone into some of these machines. I especially like the gearbox mechanism on the 2nd video to change from raising to extending the arm.

Arduino and ARM microcontroller

It's been a while since I wrote anything at LMR, so an update is due: I've been messing about with an Arduino Duemilanove that I was given for Christmas 2008. I've done all the usual things with LEDs, servos, LCDs and the like.  Also spent way too much time at the Arduino forums!

Robot arm design, my ideas and progress so far.

Armpic2.jpg

Building an arm for your robot can be the hardest part of robot design. There can be many different designs besides a humanoid design. For example you might have a CNC style XYZ axis or even a tentacle design where multiple joints are surrounded by cables. For BoozeBot I've decided to go for a humanoid design because I would like him to be able to pick things up like a person would. Reguardless of your design the first problem you are likely to face is strength vs weight.
