What does it do?

I'm working hard on a arm with 2 axis without a gripper in the first version. that will interface with a pc or a cotroller pad with a lcd display 16x2.

a BoeBot with no name

What does it do?

roam with no specific goal...

Second-hand BoeBot

With the whole 2K eeprom and the luxury 13 words RAM

Fitted with the Ping, a compass, the quad QTI kit (2 used as kindof wheels encoders)

+ all the std Parallax accessories

Currently just roaming, go to the nearest object, and trying to track with the ping

update: now with IR Remote Control (don't know yet what it could be used for...)

update: new ultrasound cartography (uses trigonometry to calculate distances between multiple objects)

update: new 'go to the closest object' algorithm using the compass

PicAxe 28X1 memory tricks

mintvelt — Sat, 15 Nov 2008 16:51:54 -0500

The picaxe 28X1 has some very cool memory features that can be used to free up program space or to give your robot a more convenient user interface. This post describes some of the things I’ve come up with during the last couple of weeks programming my Edward bot.

An Intro to arrays

Zanthess — Sat, 29 Nov 2008 02:06:40 -0500

Update: I added a video with my grad cap hacked with 64 individually addressed LEDs! This multiplexing/matrixing/array-ing sure is fun :3

This is pretty barebones so far. Be assured, more infomation will be added as I push along.

R3M3 Version I

What does it do?

Rolls, waits for me to tell it to do something

When I started R3M3, a month ago, I was using a BS2 for the core intelligence. Aside from price, I enjoyed the simplicity of the Basic Stamp. However, I have since been turned onto the cost-effective-tiny-form-factor PICAXE. So I swapped out the BS2 for a 40X and have used a 14M and an old NES Advantage as it's core controller.

Upcoming upgrades include beefier 36mm BaneBot gearmotors, quadrature encoders, and closed loop data logging.

Junior

OddBot — Thu, 06 Nov 2008 23:43:53 -0500

Primary image

What does it do?

Maps enviroment, explores with arm, falls over.

He's nearly ready for his first video! I just have to write something more sophisticated than diagnostic routines. I've saved the schematic as a jpeg so that you dont need special software to read it but it is big so save it and view it with a photo editing program.

Updated with more pictures and a full schematic of both Junior and the Laser RF MkII. I'm trying a lot of new ideas at the moment so I'm not certain when he'll be ready to video. Everything has been tested to some degree individually so hopefully he will be done in the next week or two.

robotwo

Primary image

What does it do?

Navigate around

The Robotwo is inspired by fritsl "how to make your first robot".
My goal is to let the robot drive around my living room without any human interfering.
However my living room being a bit of mess sometimes thats not so easy.
Robotwo uses 2 switches configured as a bumber, and the ultrasonic sensors SRF05. The SRF05 is mounted on 2 servos so the sensor can look horizontal and vertical.

inter-Picaxe serial communication

mintvelt — Thu, 27 Nov 2008 16:57:58 -0500

Picaxe serial bus

This walkthrough shows you how to make multiple picaxe chips talk to each other using 1 line. This works for all picaxe models but I only used the 08M in my test.

5' 4" Robot With Robotic Arm

Al1970 — Fri, 28 Nov 2008 01:59:14 -0500

Primary image

What does it do?

This remote control robot is 5' 4" tall. It can lift an object as small as a ping pong ball to as large and heavy as a glass vase 45" in the air. All the DC motors are PWM controlled so that you can make fine movements with easy. The PIC was programmed to decode the signal from the transmitter and to PWM up to 8 DC motors. It is also able to take commands from another CPU or PIC to controll the DC motors. The robot uses 5 DC motors. All 5 motor drivers were hand built.
