 greetings,

This is my first thread in Robo Community. I have very little experience in robotic and still in learning stage with parallax basic stamp2.

 My intention is to buy walle robot and hack or do some mode with basic stamp. I think this robot is suitable for modding.

 Please give me some advice before I spent all my pocket money.

First of all, Interactive Wall-e has only 1 motor, which moves the head and arms around. The U-command has 2 motors, which are used pretty well- One motor is used as a drive motor( one direction makes it go forward, turning it the other way makes it turn right) and the other is used similarly to turn the head and move the arms, and reversing it moves his eyes. Hope this helps.

Go for the U-Command Wall-E. It's tread driven drive is pretty powerful so it has good mobility and that should be a plus. Also, you can always try do things with the infrared receiver on it that receives commands from the infrared remote. Plus you have the remote to tinker with. I don't know much about the arms, they move but not in a way that convinces me that trying to get them to do any real work would be feasible without adding new servos of your own..

Thanks for the input and suggestion.

roschler, this is my plan

1.To have Ultrasonic sensor for navigation
2.Infra red sensor for side and back object ditection.
3.using ULN 2803 for motor driver. (If I choose U Command wall-e)
4.Using modified servo for tread. (If I choose interactive wall-e)
5.Transistor as a switch for try me button.

It's difficult for me to choose between this two because U Command Wall-e only have one motor for the tread. Maybe I will put 2 motor to drive, Thats the problem.

Any Suggestion?

Thanks.

Hi,

I bought U command wall-e yesterday. I dont think i will do any mod at the moment.
My 6 years daughter love it very much, especially when he's looking for eva.

I'm working on the U-Command right now and will be adding a dual motor drive system, Ping sensors, front door open and close, servo arms, tilt pan functions to the head, advoidance sensors on front and back and bottom, I've been programming the wall-e for 4mem8 and using this as a platform for his Wall-E project. Still alot of work needs to be done but the U-command is perfect for this, plus I'm using the BasicStamp2p40 for this project
Jax

Edit- If you are just learning I have a thread under the elvis alive fourm on pbasic with samples of code that I have written for both the wall-e and the Elvinator feel free to use and change the programs around to suit your needs

GW are you going to replace the controller board with bs2p40 or combining both.I wonder how you are going to get the sfx out of it after putting all the sensors.
The sfx makes wall-e alive.

The sound effects will be from board from the interactive wall-e and the emic-text-to-speach with a voice changer on it that I am working on to get the voice right. the u-command board will not be used as the Wall-E will roam on his own and will do what he wants to do with no human control.

How many sfx from interactive wall-e?
Are you going to leave the sound sensor as it is and make the sfx out by using switch to the try me button from other sensor?
It's a waste for the u-command board.

Is there nothing else we can do to get all the sfx out of the u-command board?
It's only 4 sfx from the try me button.

I think it's 6 or 7 sfx, one being the track movement triggered by a switch when the tracks are moved. these switches will be incorporated into 2 i/o lines on the stamp. the only way to get the sfx off the board is to record them on a digital recorder since the sond device is nder that black epoxy blob.
Yes it's a waste for the u-command board but it could be used in other projects as well just image another bot you want and use the remote to control it.

Any progress on your u-command. How about posting picture guide on how to open it.
I'm not quite confident to open it as i afraid i will break the track.
Hope I'm not asking too much.

brickbob: Welcome aboard, You have the right commander at the helm asking questions about the Wall-e projects, GW is the person doing the code for my Wall-E project and as you know using the U-command [ got it right this time GW ha ha ] as a test bed for the BS2P40 and it's sensors. This project is a little more complex than most, but the principles are the same for your project. Above all brickbob have fun with your project.

Thanks RobosapienV2-4mem8 and by the way congrat for the first place in the competetion. You deserve it. I wonder if i could have all the tools and time.

As for the code GW mention earlier, I still can't find it.Maybe u can add a direct link to it.

I have a few parallax product with me.

2 HB 25
1 memsic 2125
1 HM55 compass
1 Ping Sensor
1 Color Sensor
2 set Quadrature encoder

I still hope i can have more time for this.

For the time being I still enjoy with the U Command.Already have change 4 set of battery. Waaaaal-e.

Thanks for the congrats brickbob. You have a few nice Parallax parts there. The HB 25 controllers are nice but to big to be used in a Wall-E, unless it is going to be bigger than my 150mm x 150mm x 160mm high.  Code below for Wall-E.

Thanks for the link 4mem8.
GW has done impressive coding for you.I can't wait to see your wall-e strolling on the street.

I'm not going to use HB25 for wall-e.I bought that on my early stage of learning before I know that I can use Hbridge.Further more I don't have time to make the H bridge circuit.After all I will use it for my bigger Wall-e or other project if I have enough resource.he he..

Still waiting for the pic guide from GW. As for this evening I will let my daughter play hide & seek with Wall-e.

Thanks for the comment on the coding but it is all using simple commands so everyone can follow along. If I use harder commands that will through ppl off but in the end results I have no choise but to use the more harder commands but I'll try to document them to let you know what is going on. As of the Pictures I still have not had the time to put it back togeather and then take it apart. I'll do that today as I am on call because of the big storm FAY that is heading our way. So hang tight and I'll get them posted but I may add a new thread so I can control the Gallery. Also I'll be using the Twin-Motor Gearbox from TAMIYA which you can get for 10 - 13 bucks US of course

Jax

PS If you don't have time to make the H-Bridge this is going to be a nessary part of the Wall-E to control the track motors, unless you modify some heavy duty servo motors at around 150 to 200 bucks to control the tracks and then you will have to change the driving coding as well. This will also increase your weight as you'll need more battery power as well then space is going to be an issue with the U-command.

Hi GWJax

    I know you are using simple command but for me which on learning stage you have shown some good example and I think many out there are as me. And for me to join in this forum and knowing people like you are very much appreciated.

    I think you should start a new thread to make people with same interest to join.

    As for the pic, just take your time.I can get the Tamiya motor here around 15 - 20 bucks and dont worry for the motor control. I will use LM293 motor controller. It's a simple circuit I can implement on a protoboard.

Brickbob: the motor controller we used is an LM 298 not LM293, The LM 293 is a DUAL DIFFERENTIAL COMPARATOR.Not a motor controller.

Hi GWJax & 4mem8,

Thanks for the input. Sorry for the wrong info on the motor controller. What I mean
is L293D. I have experience it before with BS2 and suitable to run a motor under 600mA.I don't know how much current should be good for the Tamiya motor. But if it's not suitable I will go for L298. The only thing I don't have the schematic for L298. Where can I get one?
