In an attempt to find a saner approach to my online photo storage I'm in the process of retiring the gallery install here on Straylight, so photos from the robotics projects can now be found in this flickr set. All of the blog entries should have been updated to match, ...

The latest hardware revision includes the upgrades I mentioned in the previous post: there's a compound eye IR board (above) replacing the sharp rangefinder; a laser pointer also mounted on the pan/tilt servo; a physical switch to make sure that can't be accidentally operated; and a voltage regulator to ...

Here's the first build with the new base and omniwheels; the bot is otherwise equipped as before, but I figured it was worth renaming and versioning in anticipation of future improvements. I've abandoned the expense-ometer, however :-)
My first plan was to screw-mount the qwerk board further back, so that ...

After my earlier post in search of a base unit, this alternative appeared on LMR. It's from DFRobot but available in the UK through Yerobot, and although designed for Arduino-based projects seemed big enough to accommodate the relatively huge Terk board. There weren't many details on what's included, but given ...

If you're particularly attentive, you may have noticed in the previous post that I've adjusted the sensor mount on the pan/tilt unit. The original plan was just to tighten up the pan servo's attachment to the base, as it was wobbling around quite a bit, but I'd also found that ...

A while ago I picked up a small speaker without realising that I'd need to solder wires to it; this weekend I corrected that mistake by obtaining a soldering kit from Maplin. Whilst there I also picked up a "familiar tune" electronics kit after spotting it had a more impressive ...

I've made a few minor revisions since the last build description, so I figure it's worth an (incremental) update. I've been working almost entirely on the pan/tilt unit, which is finally attached to the top plate in the suggested manner- that is, with screws! The IR sensor is also mounted ...

Yep, more shopping. I found the Technobots site recently whilst searching for screws to support the pan/tilt unit, as the velcro tape isn't coping too well. Whilst there I somehow ended up in the lighting section and so some Dimension Engineering Ultra Bright LEDs made their way into the basket, ...

Connecting a servo to the qwerk board is simplicity itself: just attach it to the pins at the front of the board, with the yellow lead nearest:
However, if you're making the pan/tilt unit I highly recommend centering the servos correctly before putting it together, as it's next to impossible to ...

The Qwerbot+ 'recipe' differs from the basic model only in the addition of a pan/tilt unit; this allows the camera to look around independently of the base, and is supported in the TeleOp software interface. I also attached an IR distance sensor (upside down!) to the camera mounting bracket, giving ...
