Pwm Servos Movement Range

Im using hitech  pwm servos with ezbv4. The movement range is  180 or more, but ezb software doesnt allow the  whole range. Can Synthiam make a plug-in for configuring the range as required ?

Script Execution Is Not Shown By ARC

I have installed the new ARC , and  made some scripting with it. I noticed that the console window, where ez-b used to show each statement during execution, now only displays  start and done, no statement. Why ?? is it a bug ??

Hitec D845WP Servos Cant Move Slow And Smooth

Im testing a new robot , using ezbv4 and hitec D845WP servos with lipo 7,4 V batteries. (I never used these servos and such high-current batteries before). These servos are very quick, expecially with lipo batteries. So, when I program an action, I cant get a smooth and and slow movement, no matter how  I set delay, step and speed in the action...

Servo Speed (Delay,Steps,Speed)

Im trying to coordinate accurately the joint movements of a walking robot. So I need to understand how to control servo movements with ezb. Writing an Action, I find delay , steps , and speed. I understand well how a servo works. Its obvious for me what delay and steps mean, i.e I can send the command in steps , and set the delay between steps, in...

Camera Tracking Never Stops

Im going on with ezb camera experimentation. I have experimented color or multicolor tracking . The x and y servos actually track the colored object and put it near the screen center, but they go on indefinitely moving around the screen center, with wide oscillations. I adjusted the x and y increment steps in the configurazion window, reducing them...

Camera Color Tracking : Servos Dont Move

Im testing ezb camera. I had the click-camera plug-in working. Now Im testing color servo tracking. I set the tilting x and y servos for color servo tracking, and their min and max the same way as for click-camera , then enabled servo tracking. I can see a red object moving around on the screen, but servos dont move at all. They remain where they...

Camera Cable Connector

ezb camera cable is too short. I need a longer cable. I searched the community but didnt find a good solution. The connector is a special connector custom-made by ezb, or is there some standard connector I could find from connector makers to make an extension cable ? What kind of connector is that ?

Ezb And Leds

I wish to control LEDs by EZB . I saw in a tutorial leds connected directly to digital outputs without current limiting resistors. The leds Id use sink 70 mA at 3,3 V . I dont think EZB could withstand such currents ! EZB specs only say the pins are TTL compatible but dont say whats the allowable current (high and low level). Whats the allowable...

How To Stop Mp3 Playing

Im teaching my robot to dance. It dances well, with sound servo v4 and mp3 files. I need to stop mp3 playing, to give other commands or play other music. The only way to do that I found is the stop button in the soundboard v4 control itseIf. I need to use some command , such as a speech recognition command. How to do that ?

Speech Recognition Language

EZB prompts me to select a language in speech recognition configuration window , But there is nothing there to choose from. Its blank. I have a mic connected , working well for EZB recording. I use win 7. What should I do to activate this function ?

Ezb Windows Software

I saw there is a 2017-3-20 new release of ezb software, but it requires win 8-1 or more. I use with my robots an old pc with win 7 and an old release of ezb software. Will the win 8-1 version work for me ? Can I get somewhere the last release available for win 7 ?

Sound Servo

Id like to experiment servos simulating the robot mouth moving while EZB is speaking recorded messages. There is talk servo, but this control seems to be only for speech synthesis. Theres sound servo, but this doesnt seem to be for recorded messages. How can I get servo movement from the pre-recorded messages that are now being spoken from...

How To Stop A Moving Servo

Im learning how to use EZB scripts. Im doing a very simple exercise. I make a servo move , and want it to stop it as soon as a sensor makes a digital input high. Id want to see how long it takes to actually stop. I use release to stop it (its a digital servo, it will keep its position even with no signal). I see no other script statement to stop a...

Relationship Between Master And Slave Servo Positions

Im experimentig the interesting relative servos function, and I dont understand the mathematical relationship between master and slave servo positions . Can some ezb expert write some equation or a flow-chart describing what the position of slave servos will be, in function of the master servo position ? considering that each servo has its max-min...

Floor Map. Whats For ?

hi guys. I experimented floor maps. All they seem to do is creating .jpg files with a line showing the path the robot has gone. What might be the use of such images ? I need some way to store the path and make the robot rehiterate it in an an automatic way , else than writing a detailed script with a long list like this : forward, sleep(1000),...

Any News For Indoor Navigation?

I opened a new discussion named floor maps, whats for ?. I was asking what I might do with that control, but nobody replied . I thought it might help to perform autonomous indoor navigation. I saw many old (3 years) community discussions asking for the same issue, but floor maps couldt help, and there was no ezb solution for that. Dj Sures was...

Arrow Keys And Auto Position Panel

Is it possible to have moviment panel working with its actions, but having at the same time the possibility to control motors with hbridge and Arrow Keys and even keyboard commands ? It seems not possible. Everyone disables the other.

Ez Scripts And Microphone Records

Im a newcomer in EZB. I recorded some messages using microphone control, and transfered them to soundboardV4. Clicking play there i get the messages spoken by ezb. But whatever script can I use to have them spoken in my actions ? I found only text-to-speech (i.e. sayezb(...) statements. Nothing for recorded messages. Can someone help ?

How Fast Are Scripts?

Im entering Ez world now. I made many robots with embedded controllers (PICs) I designed and programmed. Now Im exploring ARC, and trying to understand what it can do for me. Scripts seem a powerful tool to make my robots go. I tested them with a simple rover, and with surprise , I realized that the response time of ez scripts was extremely long...

ARC And Third Party Servos

I tested ARC with hitec servos, and discovered ARC is not able to make them move in their full rotation range, largely exceeding 180. The full ARC 0-180 range produces a rotation of about 163. And , of course, no corrispondence between the degrees set and the actual servo position. I was told by DJ Sures, that ARC was made for ezb servos, and...
