Write LMR (Manual Mode)

I was filling some gaps of time and once again, started playing with my little drawing bot. A truly sad little bot that has never really found a calling and receives none of my attention. Never the less, I did manage to build a nifty pen-lifter thing and stick a bluetooth module on. As seen in the video, just regular ol' RC control (except via the tilt of the Android phone) with a Sharpie stuck down the middle.

Please don't expect to be impressed.

Rocketbot robot controller and wireless fun

So recently I decided to purchase a bluetooth module in hopes of pairing it with my phone in case I ever wanted to show off a robot to someone. In my quest to find an android app for my phone, I came across three. The first is the cellbots app (more information found here: http://www.cellbots.com/), which include a .pde file that I tried to deciper for some simple functions but ended up giving up after a few hours. The second is the amarino plugin available from here: http://www.amarino-toolkit.net/.

Wii Camera BreakOuts

I just finished and sent off some break out boards to support a wiicamera. These boards use the camera after it has been removed from the wiimote and communicate via i2c NOT the standard bluetooth connection of the wiimote. Included on the board is the necessary reset circuit and 25mhz crystal. There are a total of (4) .9" mounting holes to match 2-56 hardware. 2 of these holes match the hole pattern of the servo horn of the "LMR standard" blue servo. Pull-up resistors are also on board for the i2c lines. The board requires and has a 5-pin header for:

Line Follow PCB's

I just got an order of PCB's in and well, I just gotta show them off...

This is a line follow sensor with onboard i/o expander. All 8 sensors can come in (via i2c) in a nice, clean binary byte while still giving you access to each individual sensor if you like. There are 2 mounting positions allowing a forward posistion for curvy line-follow as well as a "closer to the robot" mount for straight-line maze stuff. If nothing else, I am posting to remind folks that boards do not have to be square! Radius your corners, add some details --Don't be afraid of curves, my friends!


Note: You can follow some projects some of the time, but you cannot follow all the projects all the time.

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.
