Robot kit

Tijdens de robot presentatie (na de openingsceremonie) wordt uitgelegd hoe je de robot kit kan bouwen

Software pre-requisites

USB UART Driver https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

Arduino IDE - https://www.arduino.cc/en/Main/Software

Visit https://github.com/Fri3dCamp/Fri3dBadge

Also read the README in this zip for tips on how to configure Arduino IDE for the Fri3d Badge.

Build instructions

YouTube video met bouwinstructies: https://www.youtube.com/watch?v=ZcMtFPezIq0

• Robot body can be assembled inside out, with motors oriented wrongly
• Battery is difficult to fit, but it does fit
• Careful assembling the feet, don't push in the center, but at the sides or you risk breaking the wood
• After assembling the feet and hips and before fitting everything together, calibrate the motors
• Some examples during building

Calibrate motors

Install calibration program

where do I find the calibration program?

If you have installed the Fri3dcamp library inside the arduino IDE, you can find the calibration under the following menu item:

File > Example > Fri3d Camp Badge > 4.Kits > RobotKit > MotorCalibratie

how to calibrate the servo's?

Once the calibration program has been flashed on the badge (use USB port of Badge, not on motor controller), you will be able to calibrate the servo's.

The following buttons can be used to navigate and manipulate the application:

BOOT

Go to the next step in the progress (the step you are in is visible as the number of LEDs lit in left displays)

BTN0

Up

BTN1

Down

1. Choose the servo to calibrate (S0/S1/S2/S3 is shown on right display)
2. Navigate the servo to the 0 degrees position (left display shows "-")
3. Navigate the servo to the 180 degrees position (left display shows "+")
4. Save your changes (with buttons select "V" on right display instead of "X" on left display)

Questions to be answered in this wiki

Need for detailed description for physical manipulations during calibration, for each motor:

what is 0/180 degree reference (left or right, direction w.r.t. robot, mirrored or same for left and right motors?)

what is best assembled, what unassembled or temporary assembled during calibration?

what to do w.r.t. the physical range of the motor, which is only slightly larger than 180 degrees?

how to continue calibration when motor starts vibrating at end of range?

Do I lose my calibration if I install another application on my Fri3d Badge?

Can I calibrate an assembled robot?
