IMPORTANT Edit: A huge thanks to @Bill SCHONFELDER who has carefully put the calibration procedure through its paces. Bill spotted a problem that I had not come across which has now been corrected. The Blockly code has been updated, the GUI did not need changing.

Please remember that this code is for Windows based machines only and will not run correctly on an emulator on the Mac. For Linux or Mac OSX you will need to build the application from the source code using Processing. All of the files are available for you to do this in the single zip file attached.

Thank you Bill!!

OK. You have carefully followed the instructions on how to build Otto and have made sure that all the servos are centralised (set at 90 degrees) before you attach the horns. You are now at the very exciting moment where you check to see how Otto moves and dances and so you upload your first simple Blockly code.

:( What happened? Why did the legs and feet move out of position? Otto doesn’t look right and doesn’t move smoothly.

Do not be disappointed and do not worry! This is completely normal and happens in every Otto build. This is the stage where you need to adjust the central positions of the servos using a simple process called calibration. This will only need to be done once and then the correct positions will be remembered every time you turn on your Otto.

Hi Otto Builders!

I have created this project to collect all bugs, blocks requests improvements and ideas for the next release of Otto Blockly.

@Bill SCHONFELDER @Birger T @Ian Shatwell @ArisBlocky @Ross Rabette

Just reply please with the exact name of the block or new block idea screenshot of how it should look will be helpful and a link to the post/project where it has been discussed.

These are the ones I have collected so far

(I will be editing as you reply and updating as is implemented and new versions appear):

• Calibration blocks for Otto wheels @Piers Kennedy
• Otto wheels blocks
• Array and string blocks fix
• More math and text blocks
• Creating a pointer variable, to store an address of another variable and/or a function.
• Print / read strings and chars from PROGMEM
• Bitmap and animations creator with Zoom library @Nicolas
• Emotions blocks across all LED matrix and OLED
• Compatibility with the new Raspberry Pi pico @Oscar Ferruz
• Create a block to upload the Otto Scratch AI code @Camilo Parra Palacio
• Create a Analog ADKeyboard module block
• Add Otto Quad blocks and libraries @ROBERTO GERLEIN
• RTTTL mode unblocking.

Long Term road map

• ESP8266 watchdog
• Operations for server
• Crear simple html for web server
• Blocks config wifi server and client
• Cayenne
• Servo pending if need dropdown
• Buzzer pending if need dropdown
• Create a Encoder sensor block
• Create Blocks for multiple images for the tft display screen 160x120. Right libraries.
• Pixy cam2
