The NXP Cup EMEA

We took the free time during the Corona lockdown in Germany to create our own shield for FRDM evalboards, that is supposed to control autonomously driving robots ( especially NXP Cup vehicles ):

https://mygit.th-deg.de/nxpboard/layout/-/wikis/uploads/a8cff406fa73ac9803f498740727d885/rendering.png

The board has the following features:

  • Power input with PTC fuse and reverse polarity protection ( 6 - 15V DC )
  • Control of two DC motors ( up to approximately 20A ) with current sense, motor fault detection and back emf measurement ( for rpm control )
  • Control of two Servos at 6V DC with adjustable maximum current
  • HMI with 2 potentiometers, OLED Display connection, 8 dipswitches, 4 LEDs and two push buttons
  • Reset button
  • Power control LEDs  ( 3V3, 6V and VBAT )
  • SD-Card slot
  • Connector for HC-SR05/6 Bluetooth module
  • Connectors for 2 linescan cameras
  • Connectors for 2 wheel encoders
  • breakout headers for 2.45 soldering breadboard on top side

Furthermore our shield is backwards compatible to the FRDM-TFC shield, so You can easily adapt already existing code to the new shield.

During the last weeks we assembled the very first prototype and tested it on an Alamak car with the FRDM-KL25Z:

We had some smaller issues that could be solved with some jumper wires :smileyconfused:, but after all everything seems to work reasonably well :smileywink:.

Next week we will order the redesigned version and also publish the KiCad project and other documentation on GitHub.

You can already view the schematics attached to this post.

We really wonder how the NXP Cup community is interested in our work and if there are some more features that should be added :smileyhappy:.

In the videos you can see the NXP Cup car (old model C type) avoiding a WHITE obscacle (white polystyrene cube or white snow, according to the current winter situation in Bavaria ;-)

Happy New Year to everybody! Please find have attached a simple CodeWarrior project for the Alamak car. It is very basic, less than 300 lines of code, but the car has completed a sucessfull lap on our training race track. The project is just for test purposes, not yet optimized for high speed. Have fun! Gerald

     After NXP FTF, we went on to visit American Maker Faire on May, 22, 2016.

     As a member of LANDZO Maker Space, hope that there are more and more friends join us.

     Let's review those fantastic Maker works.

"Where Inspiration and Design Connect". I like it, the topic of 2016 NXP FTF.

As the cooperative partner of NXP University Plan, LANDZO has arrived in Texas, Austin on May 15,2016. 

To satisfy our technology enthusiasts, we try to share excellent pictures at the scene.

The 1st group pictures from Technical Sessions:
