Wavefront Algorithm Mapping

Hi, LMRians. I've been reading up on this Wavefront Algorithm Navigation and I understand bits and pieces of it, but not everything. I'm trying to learn up on it so I can use it in my next robot : Project 4L-FRED (Alfred), a butler robot. The robot is suppose to navigate around the house from the dining area to the living room and serve drinks to guests. The robot will have pre-recorded messages like greetings and stuff like asking what drinks the guest would prefer.

Chickenparmi's Blog

Hello again everyone, my name is chickenparmi.

As suggested by ChuckCrunch I am making this blog post to give you a brief explanation of my past experience/knowledge in robotics and all the things I have made. I will post all my old stuff in this blog and stuff that I dont think to be worthy of a robot post as to avoid post spam.

Driving a CNC machine directly from an STL file with a DAGU Spider controller

I want to drive a CNC milling machine using only an Arduino processor and an STL file. The STL format was chosen because it is very simple for me to understand and almost all 3D CAD software can export an STL file.

In my forum post here: http://letsmakerobots.com/node/34958 the feedback I go was basically.

Spider controller

The DAGU Red back Spider controller is an Arduino Mega (1280) compatible controller that is especially designed for driving a large number of servos. All 70 I/O pins are terminated in servo compatible 3pin male headers as well as the standard female header and the power supply is a switchmode power supply delivering 5V @ 3A from an input voltage of 7V - 32V.

New Micro Magician V2

The new improved Micro Magician V2 is here! It has all the features you loved in the original Micro Magician but with an ATmega328P and improved power supply. The new black and yellow PCB looks great and is easier to read.

You can now download the manual from here: https://docs.google.com/open?id=0B__O096vyVYqUjNXVV9RMmFuNkk

Features:

Prototype animatronic head

Well my boss is involved in organizing a robot head building contest in China and asked me to make an example to inspire the contestants. I know many will just be made from cardboard and wood but I decided that if I was going to spend time on this project then I wanted to make the most of it and develop a new product.

Doodle Bot on Instructables and MAKE Projects

Well I sent 2 Doodle Bots to Andrew to show at Makers Faire and for anyone interested I have now put detailed, step by step instructions here:

Robot A.I. idea for non neural network approach.

In this Blog I am simply gethering my thoughs in preperation for a long term project. Hopefully some programming Guru's will post some good ideas. Maybe it will inspire someone else. I am just one nueron in the huge brain of humanity.

Personal History
When I was 12, I taught myself to program in GW basic on an IBM clone that ran at 8MHz with monochrome, text only graphics and a 5¼inch floppy disk drive. At that time I wanted to write an artificial inteligence.

Artist, first time robot creator

Hi everyone. I'm an art student who's doing my instillation for my Advanced Drawing class on automated art and the creative power of robots. Needless to say I'm quite lost when it comes to the mechanics of it. I got ideas, but ideas don't mean shit if they're not backed up by knowledge. That's why I'm asking you guys for help, and hopefully I can take the advice and use it to make some really effective pieces.

 

Axe - the sumobot

Hello hello!

As you can guess, I am making a new robot, and it is a small sumo!
Features:
- Picaxe 14M
- 2 modified micro servos
- 1 LDR to see the line of the ring
- Sharp IR sensor
- Bottle cap wheels until I make up a better solution (Yes, lol :D)

And when I will receive parts, or get something done, I am going to update this until it is time to post a robot!
Tomorrow (I think) I'm going to post schematics and maybe printed layout ready to make it pcb!

Robots in OUTERSPAAAAAACCCCCCCCEEEEEEE

10 pts to whoever gets the title reference.

I was perusing all the amateur DIY near-space balloon flights that have been gaining popularity lately, and a thought hit me.

Would it be possible to have a two stage flight; first stage would be the balloon and payload reaching a certain altitude. The second stage, when this specific altitude is reached, a ROCKET is fired from within the payload, taking it further into space (hopefully reaching escape velocity.

After the MkI chassis bellied out on the stairs I rebuilt the chassis to give an extra 55mm (about 2inches) clearance in the center. The new chassis is also 50mm … Read more

New MkII robot gripper from DAGU

Dagu has had an aluminium gripper available for some time now so we decided it was time for a re-design. The new MkII gripper has some significant improvements on the original.

  • Brass sleeves in the joints improve rigidity and eliminate the need for adjustment.
  • A 2:1 gear ratio increases gripping torque while utilizing the full 180° travel of the servo.
  • A spring loaded clutch protects the servo gear train while providing spring tension for gripping objects.
