Hello to everybody!

My name is Luis García and I'm the developer behind HelloSpoon robot.
What is HelloSpoon? Well, HelloSpoon is a mobile based robot inspired in a baby elephant to spend with children with upper limb difficulties, children with special needs and elderly three of the most important hours of the day for all of us (breakfast, meal, dinner).

Here I want to share with all of you one video of me testing HelloSpoon before doing the real testing with children and elderly, just to be 100% sure that HelloSpoon is safe enough to share some time with other people :-)


A little thecnical info about HelloSpoon:
HelloSpoon is using as main core one mobile app with PocketSphinx as voice recognition engine, as servo controller I'm using one OpenCM-9.04 type B and as the robotic trunk I'm using the "new" Dynamixel XL-320.

HelloSpoon is a project I've been working on for a bit more than a year, first it was using Dynamixel Ax-12 servos but when XL-320 where presented at the beginning of this year I started to use them because one of the main ideals behind HelloSpoon is offer an affordable, fun and easy to use robot.

Please feel free to leave a comment, if you like it, if you hate it, anything :-)
And if you like, why don't share it in any of your social media? So more people will know that a development like HelloSpoon is being made :-)

I am unable to discern anything useful from your photo, due to its poor quality and non descript content.

Try and look for any labels or numbers written on the motor, perhaps you can find a part number or spec. Google any numbers/words you find if you don't come up with anything post them here either as a quality picture or typed (ideally both ways) and we can see what we come up with.

If u cannot identify.........then do you know any such kind of motor which can
rotate 2-3 kilogram of weight effeciently?How can i get it?
This is not sufficient information to spec out a motor, you need to identify any static and dynamic loads on the motor, such as acceleration . You also need to identify the speed and voltage at which it will operate. Additionally there are different types of motors to chose from and some may have extra features such as an encoder or brake.

can anyone please identify the name of motor in the pic.
If you know it.....then please tell where is it available (how can i get it)

Async requires strict timing on the sending and receiving sides. Each bit has a fixed time period that both sides know. It also uses a START bit to tell the receiving side when the data stream starts.

Sync uses a clock, typically on another wire, that synchronizes the sending and receiving side timing. This way the receiving side knows when a bit is valid from the state of the clock signal.

Now go do some web searches and reading. It can help tremendously if you draw the bit pattern wave forms and send/receive data with pencil and paper. It is not that difficult once you spend the time the understand the concepts.

Then try writing code to do serial transfers by bit banging.
I apologize in advance if this seems quite tedious, However I am quite confused with the way robotic I/O works as well as synchronous/asynchronous and I am having a hard time trying to understand them. Please if anyone would be so kind as to explain these three things in a way a beginner can understand I would be incredibly grateful. Thank you for your time.

Does it do anything?

Can you make the LED turn on?

You say that the build was OK, but did it actually program the chip? Did you see the light on the programmer flash orange for a couple seconds? The process for setting up the AVRISPmkII is different than the tutorial.

Did you use the exact same chip as in the tutorial?

Do you have tools like a voltmeter that you can use to check the circuit?

hi everyone so me and my friend are makign the 50$ robot for our final project. We have followed all the steps so far and we are now stuck at a point where we cant get the robot to run, we use AVR studio 4 to build the program and build was successful but the robot still doesnt work? idk what the problem is can someone possibly help us out. i will answer questions as best as i can.
we bought the AVR ISP2 Programmer

Move your mouse cursor to the upper right corner of this web page and click on where it says "Robot Tutorials".
Lots to read there to get you started.
