Let's Make Robots!
This is the fusion of my old Qwerkbot project and a 4WD base, with omniwheels replacing the originals. I've also attached one of Oddbot's compound IR sensors for … Read more

Qwerk control with Processing 2

Here's some more progress towards a processing-based control panel: got mouselook video feed, and keyboard controlled motors/LEDs/sound effects now! Also, I've upgraded to filming in High Def (that version is here- http://www.youtube.com/watch?v=rMHlcNt5O60&fmt=22)

Qwerk control with processing

So I was doubly inspired by Chris the Carpenter's recent experiments with robot control via processing, and f5pql's heavily-equipped qwerk-based robot to do some more tinkering of my own. I'd been programming the qwerk for autonomous operation through the SimpleRobotClient, and controlling it directly through the telepresence DiffDrive client, but was beginning to wish I could somehow construct a hybrid of the two. But building a client from scratch - or even just tweaking the existing ones - looked scary!

Not-so-mighty bot

So the Mighty Bot challenge (http://letsmakerobots.com/node/4979) got me wondering about the mechanical performance of my Qwerkbot project. It's not been optimised in any way for the task, and has no hope of winning, but maybe it's interesting for comparative purposes!

Qwerkbot weighs in at around 3lbs and is powered by a 7.2V racing pack. In the video it slowly shoves a pot of potatoes (total weight 3.5lb) the requisite metre- conveniently all the flat workspace I could find!

compass modules?

Does anyone know of a compass module that'll return heading as a voltage, rather than timed pulses or requiring an i2C interface? The qwerk board seems a bit limited in its inability to handle either of those, and the api doesn't support the quadrature encoders either so I'm trying to find a way to work out where the thing is facing!
