Let's Make Robots!

Cool resistors

As featured on the liveshow, now in ultra high res. A 3 digit adjustable resistor. 10 kOhm potmeter. It's name and number are easy to find online: Bourns 3683s-1.

A watched meter never boils

I would love to be able to have continuous readouts from my electricity meter in my home. Such a tedious job is time consuming and tedious. So I need a robot to do that for me.

BarkTrak Trailer sugestions help

 

Hi All,

I've been busy with my robot recently. I've rebuilt the voltage regulator, added a battery monitor all situated on the newly fitted expansion boards on the rear. The battery is now housed in the battery housing (Great place to house it really.)

I've also revisited my loft and found BigTrak's trailer.

Walter can play rock/paper/scissors!

We're gettin' somewhere...

This is Walter "docking" or stopping inside of a given area. I should say that in the video, Walter comes up quite short on the target. This is an issue with the beacon, not Walter. Walter judges distance from the beacon by judging the "size" of the beacon within the view of the camera. --As he gets closer, the dot of light gets bigger. When you put nice, fresh batteries in the beacon, it becomes super-duper bright and thus, Walter thinks he is closer than he is. I just need to get around to doing a bit of "regulation" on that beacon...

Enjoy...

OscarMobile

Just a blog for the OscarMobile build.

When Oddbot left Australia for his robot building job in China, I was lucky enough to score his collection that he couldn't take along with him. Included in this collection was the makings of a kickarse robot, named boozebot. Now after a couple of years, my wife and I have a son, and in a couple of years he's going to need a way to get around (walkings OK and all, but not much fun). So I'm using the base of OB's robot to make the OscarMobile:

Servo Controller: A thought experiment

First up, this is at best a work in progress, at worst only ramblings.

I have seen members asking about driving more than a handful of servos and getting the response that they can either use an arduino and its assorted libraries to drive 12+ servos, correction, up to 20 servos or get a dedicated controller board that seems to cost in the area of 50USD. I spent an hour or so knocking up an idea. I want to lay out my thoughts and see where it could or should go.

 

Real Time Lip Syncing on the cheap

Lipsyncing is the process of making an animatronic costume or model mimic the actions of speaking. I use the term mimic as it is currently impossible to make an artifical tougue or larynx that will duplicate speech. So we have to use a speaker with a recorded voice and have an animatronics track to make the movements.

Real Time Lipsyncing is where you do not have the luxury of being able to record tracks and add the lipmovements. It has to be done on the fly and often whilst interacting ad-hoc with an audience.

Starting SuperDroidBot Blog

So much is happening so fast, I'm starting this blog to document what is going on with the bot, so I can look back on my thoughts from time to time and see how they developed.  Others are more than welcome to participate!  I'll start by throwing in a diagram and some fun video!

Review: The Service Droid kit from Dagu

I have received my Service Droid kit along with the Rover 5 robot chassis on a Monday evening. Excited, I opened up the package to reveal 2 big boxes, one with the Rover 5 and the other with the actual SD kit. The base comes assembled, with a battery box, a screwdriver (with a magnetized Phillips end), an Allen key (hex wrench) and a little bag with silicone lubricant. The droid kit comes with lots of parts grouped in separate labeled bags for easier assembly. To do the assembly, I used a cutter, a plier and the screwdriver from the Rover 5 box.

Make a reusable robot base / power suply in 5 easy steps

Every now and then I want to test a circuit or a new sensor or even some new idea for code but I don't have a starter kit or anything. While shopping for some robot parts I had an idea for a simple base that could be my equivalent of a starter kit, a power supply and a small robotic platform. This is what I came up with in 5 easy steps.

I've been quite busy & I know it's coming in a bit late, but for interests sake here is some of the background footage behind my OddBot Video Challange entry.

 

IR Beacons (IRB)(XMOS CHALLENGE)

This project is based on my picaxe version of the mini ir beacon.

Some ideas to expand on this are:

Addition of phototransistors to sense an ir signal and aim the com portion of the beacon towards the target. This could be effective for transmitting location data or possibly map dataThe beacon could possibly have a link to a base station to report on bots in the vacinity.

Addition of a distance sensor for inital maping of local. This may be ommited as it adds extra detail that may not be useful.
