Movement Scripts

My Robotics Club needs a movement script since i lost my original copy. Please help! We need it to undergo basic maneuvers such as stop, go, forwards, backwards, turn left, turn right, accelerate, decelerate, and it should go up to about 5 mph max 1.5 mph min. If you are willing to contribute then please do. Please post either the script or a link...

Modified Servo Or Hbridge?

Hello Everyone, I'm just trying to figure out if I should order 2 modified servos or a Hbridge and motors. These will be responsible for the movement of my robot. If you need anymore info. let me know. -Thanks A Ton!!!!! Kolton

Do Ya Feel Me Bro?

I ran across this on eBay. I began thinking...wouldn't this be cool to add touch sensors under the plastic casing of our robots and make them even more interactive?! Image it playing a particular script if touched under its "arms" or play a sound file when pet. Here is an info grab of this particular device that only uses one input to...

Another New Guy

Hi all, My name is Dave and live on the Wet Coast of British Columbia ( thou not lately, wet that is ) in Victoria. I love all the neat projects on the site and am waiting patiently for my EZ-Robot kit. I hope to contribute some good info to the site but most likely will dish out some bad too, that's the way it goes but I can take criticism and...

Controlling Robots With Android

I noticed a pop up on the ARC today, saying that we could now control our robots with Android. Did I read it right? ??? I can't find anything on the site about it! If this information is correct I'd sure like more details!!!!!!!! Are you going to post details DJ? What app would need to be downloaded? I have a Android tablet; a Samsung Galaxy. Man!...

Robot Hands

Check out these robot hands from Custobots: https://www.custobots.com/products/robot-hands-kl01003ho Kind of expensive but they have given me ideas on how to create my own. And they are controlled with only one servo! Does anyone else have something like this?

Multiple Serial Devices On Ez-B

DJ, I see that you set both the new H-bridge and the MP3 trigger to Port D0 for the Serial communications. I already have the BV4113 Motor Controller, before I order the Sparkfun MP3 Trigger I would like to verify if I can connect one of them to an alternate port and configure it as a secong serial out port?

I Cannot Connect At All

Maybe even EZ is too difficult for me. I cannot get the computer to recognize a new bluetooth device at all. Let me say I have purchased 2 and tried both boards. I have inserted both BT usbs (sometimes a blue light but mostly not on either). Boards are powered by 4 AA one board is flashing red on BT and white on main board or ther flashing red on...

Syntax Error When Sleeprandom Function > 30,000Ms

I'm running ARC 2011.12.11.00 and get a syntax error (The parameter must be a number in milliseconds) if I enter a number higher than 30,000 for either the lowMilliSec or highMillisec values. I saw earlier code snippits posted on the forum that referenced 90,000 ms. Didn't know if this was a bug in this version or there was something I should be...

Sparkfun MP3 Trigger Issue With Servos

Hey guys, I'm using the MP3 Trigger instead of "soundboard" in my Wall-e & found that I need to constantly release the servos for sound to work properly (using ReleaseAll() in scripts). Sometimes I lose sound completely. If I setup a test project with a servo & the MP3 Trigger, the servo will shake/wobble whenever I slide the...
