Robot Building Questions

Camera Works But No Servo Movement

We assembled the jd robot exactly as in the instructions, including servo alignment. When we turn it on, the camera works but there is no servo twitch. No actions from the app are executed. How can we figure out what is wrong?

Ezb 4 Controller Connection

To whom it may concern I would like to know why do my ezb 4 restart when I'm testing my smart servos? I have smart digital servos and Dymanixel servos, but it's the regular digital servos I'm testing 1st. My Dymanixel servos are connected to a 3pin hub which is on port 5 and 6 hooked up. The digital servos are plugged in the ezb 4 thank you, Mike.

Scripting Multiple Robot Actions One After Another

I'm currently using Script Manager to run multiple scripts in sequence. I know that ControlCommand is non-blocking by default but is there a way to wait for a script to finish before executing the next? The idea is to basically wait for each robot to finish asking/answering/doing something before moving on. I've mostly been using...

Maxsonar

Hi All. I'm thinking of using a Maxsonar sensor for collision avoidance. I don't want to mount it on a servo for aesthetic reasons (will it make a big difference if I do this?). Will one sensor be good enough? Is it even possible for the software to manage 2 or more sensors? Also, there appear to be many different models / types of Maxsonar...

EZ-B V4/2 Too Slow In Wifi Client Mode

Hello, I've successfully connected to my EZ-B in Ad Hoc WiFi mode and configured it to connect to my home WiFi network.  It boots up and tells me it's connected and has a green flashing light.  In the ARC app, I can scan and see it's address (192.168.1.63 in my case).  When I try to connect to it, in ARC, the connection fails due to the operation...

Raspberry Pi Or Arduino

I am building a humanoid robot and was wondering which is better to use?  I am starting on the head from a book that I received on the Mark 1 robot project.  I am then going to research and build humanoid or at least close to humanoid legs.  Do anyone have any projects I can research and learn about biped robots.  The Mark 1 can not walk yet from...

Custom Hexapod Build

Can I use the EZ-B v4 and the ARC to make my own custom Hexapod with leg lengths that differ from the EZ-Robot six hexapod kit ?. Will the ARC be able to calculate inverse kinematics for my custom hexapod ?

Starting A New High School Ez Robot Curriculum

I am completely new to the EZ Robot world and plan to start a robotics class using EZ Robot. I have another class where I teach LEGO Mindstorms robotics. I will be ordering the JD, Roli, and Six kits this summer in preparation for the new class. If anyone has suggestions on how I should approach my new curriculum, your guidance will be very much...

Interacting With The JD Robot Via Flashcards And/Or Objects

Would anyone have suggestions on how best way to go about interacting with the JD robot via flashcards and/or objects? The aim would be for the user to give some sort of meaningful visual response that JD can interpret and process. QR codes are nice but they can be quite large particularly if the robot is further away. The only way I can think of...
