RDM (Red drum machine) YDM tribute
@ October 22, 2011
can drum and wander around
Cost to build:
$220
Time to build:
8 hours
Weight:
400 grams
- Control method: autonomous (very)
- Power source: 4 AA batteries
- Programming language: Picaxe basic
- Sensors / input devices: SRF05 Ultra Sound
- Target environment: where ever there is something to play on
I have managed to get every thing except the neck motor to play ball. it took a bit of trial and error to find the correct wiring connections as my board layout is different to what was shown in the Make Mag when I first built it its head would turn to the left then back to the centre. the motor driver got very hot now it dose nothing. Ill have to wait untill I can get another L293D and try again

Nice!
Nice robot you've been building. That red head gives it some personality i think.. good job!
Oh, and fix the little typo on youtube.. RMD=RDM ;)

sounding good
Your getting a good rhythm going there. Keep tweeking away. :)

Woot!
We have video! :) Your drum machine seems to have a bit too much self preservation instinct when it comes to 'running into things'. :)

Thanks for your input Frits and ignoblegnome
The offending speaker is only sitting there temporarily until I build a proper housing.
I will move the speaker and try the head again
Is there a way to check a motor driver without test equipment?
other wise its another week wait to get a replacement

Re: test motor driver
This will only be slightly simpler than hooking the driver up to a microcontroller. :)
Stick your motor driver in a breadboard.
L293 pinout
Based on the pinout:
Once you have all that mess wired. With the motor on 3 and 6, you can connect pin 2 to +5v and 7 to ground and your motor should rotate. Reverse the wires, 2 to ground and 7 to +5v, and the motor should reverse direction. Do the same with the motor on pins 11 and 14 and your jumpers on 10 and 15. You should get similar results.

Video = Nice - you are
Video = Nice - you are there, you just need tuning :)
To check a motor driver, the simplest is to hook up a small motor and a microcontroller.

Haha, that is cool looking
Haha, that is cool looking :)
It's going to be interesting to see how it will perform :) I think you will have some isues here:
The front needs to be flat, so it can allign - it looks as if the speaker is sticking out.
The sticks looks like they are much too long and at least one is of chrome/brass. I think they will be very hard to move fast enough.
And I am not sure if mounting the speaker on top of the moving "head" is a good idea - I think you will kill the geared motor, or have trouble moving the head fast enough.
There was a reason for the design I made - but of course you are making your machine, and I may be wrong :)
I am looking forward to seeing more!

Nice looking build. I wonder
Nice looking build. I wonder if the weight of the head with the speaker on top was too much for those little GM10 motors.
