Let's Make Robots!

BERNT

Navigates around using ultrasound and with a bumper to detect low-level obstacles.

"My First Robot" - BERNT

EDIT: 2009-02-02 - BERNT IS ALIVE! 

New video added, I know the performance sucks and all that...but i just wanted to show it. =o) 

 

EDIT: 2009-01-11 - FIRST POST

Part one of the "How to Build Your First Robot"-code is implemented with some minor changes in order to suite the somewhat different components htat i've used.

The difference from the tutorial is that i've used a  Parallax PING))) sensor and added two "bumper"-switches that actives an interrupt in the code.

The IR-Sensor isn't activated just yet btw.

This lil quite works as a charm.. =o)
It really really really annoys my poor dog as well. 

EDIT: 2009-01-15 - PARALLAX PING))) Sensor

Some of you have emailed me and asked how I got the PING))) sensor to work with the 28X1 board. All of you should take a look at the following excellent walkthrough/tip: http://letsmakerobots.com/node/1276 made by Vince v2.0

The main thing is to make sure that the sensor is supplied with 5V! ( I made that mistake)
The walkthrough discusses most of the problems that may occurs while dealing with this sensor.

 The subroutine in BERNT dealing with the PING))) sensor looks like this:

get_distance:
high portc 0
pauseus 5
let dirsc = %00000000
pulsin 0,1, w0
return 

 EDIT: 2009-01-29 - New Navigation Code

BERNT is now a little more "smooth" in his navigation and I've decided to add a video of his performance. =o) 
Next part is to make him follow a wall using his Sharp IR Sensor. Video will of course be added.

Beer is great. 

 

EDIT: 2009-01-30 - BERNT IS DEAD 

Bernt the way we know him is dead! A new-born BERNT will be published soon though, this time with some more sensors, new code and some cool accessories.
