New Concept for 2018 Mini Sumo Roboter

Doing Mini Sumo robot competition is really fun, and there is yet another one coming to end the current university semester. For several years we have used our own sumo robot, and this is the one used in the course this year too. But for future and extended events we are exploring a new robot. I proudly present the concept of the next generation sumo robot for the year 2018:

2017 Spring Semester Sumo Challenge

Video

The spring university semester is coming to an end, and the Infotronic course closed with a Sumo robot challenge. Great challenge, new technologies, innovative approaches and funny designs 🙂

3D Printed Sumo ToF Blade

ToF (Time-of-Flight, see “Tutorial: STMicroelectronics VL6180X Time-of-Flight LIDAR Sensor“) sensors are fun: they measure the time the light takes to travel to an object and back again. That way they can measure the distance to object with a millimeter accuracy. An ideal sensor for a battle robot: 🙂

Failure with Solder Points and Mechanical Pressure

The good thing with failure is: it is an opportunity to learn :-).

So here is a case: For a STEM roadshow (see “MINTomat: World’s Most Complicated Bubble Gum Automata?“), we have produced in a rush an autonomous robot with a shiny printed 3D cover:

MINTomat: World’s Most Complicated Bubble Gum Automata?

How to fascinate kids for technology? Show them that engineering is fun :-). At the Lucerne University of Applied Sciences and Arts we have created the ‘MINTomat’: a robotics system for STEM activities rewarding interaction with bubble gums:

Yes, pretty over engineered compared to a normal bubble gum automata, but that’s part of the fun :-).

Enclosure for the Remote Robot Controller with LCD Display

The first enclosure for the INTRO robot remote controller board (see “INTRO Robot Remote – First Production PCB“) is ready, and it is looking good:

INTRO FS2016 Semester Closing with Robot Maze Challenge

“Learning-by-doing” is one of the core principles of my embedded systems and robotics course at the Lucerne University. For this the students apply what they learned using a robotics platform. In earlier semesters we did a Sumo battle at the end. This time the challenge was to build a remote controller plus to add the ability to explore and solve a line maze:

Flashing many ARM Boards without a Host PC

So here I have 50 new NXP Kinetis K22 Robot boards (see “Zumo Robot with Magnetic Encoders“), and they all need to be programmed with the first firmware on the bench:

The challenge is: how to do this in a fast an efficient way, without the need for an IDE or even host PC machine?

Zumo Robot with Magnetic Encoders

We are using robots to teach advanced embedded system programming at the Lucerne University (see “Sumo Robot Competition“). Students can buy the kit, and we are running out of available hardware. Time to produce a new series of robots :-). It took us a while to get to the next revision of the Zumo Robot, but finally the first one has been produced and assembled, and I think it is looking good :-).

Impressions from Freescale Technology Forum 2015

With Freescale merged into NXP, I guess this was the last FTF (Freescale Technology Forum) after a history of 10 years. Maybe it will transform into a ‘NTF’, at least I hope that such an energizing event and conference will continue in the new NXP area. I was busy with delivering my own sessions, but had time to meet and greet and see a lot of interesting stuff. After visiting the TechLab several times and after all the discussions with other embedded enthusiasts I have now many cool projects in mind :-).

So what I do here is to share some impressions with pictures and videos. It will take me weeks to absorb everything. Not to talk about the huge email backlog I have now ;-). So enjoy:

Snow Plowing (Darth Vader) Sumo Bot

Finally, winter with lots of snow arrived in Switzerland. Getting up at 5am this morning to free up my front yard from the 25 cm snow which came down overnight, so I can drive my wife to work. She does not like driving in snow conditions, but it is fun for me :-). But lots of snow, I thought I could use a little helper bot:

Sumo with GoPro, and other Sumo Videos

Here are the videos and results of the Mini-Sumo competition held on 19-Dec-2014 in Horw, Switzerland:

  • Winner full-autonomous tournament: “The:Flash”
  • Winner semi-autonomous tournament: “Banana-Rob”

See “Infotronic WS2014 Sumo Robots are Ready!” for all the robot portraits.

Sumo Robot Sensor Shield

The PCB’s for the Sumo robot (see “New Sumo Robot Assembled, and looking good!“) arrived. It is the ‘production’ version of that shield I have shown in “Sensor and Communication Shield for Sumo Robot” which adds following to the robot:

  1. Ultrasonic module
  2. Bluetooth module
  3. nRF24L01+ module
  4. I2C I/O Expander for 8 extra I/Os
  5. One general purpose I/O header
  6. One general purpose I2C header
  7. Up to 6 infrared distance sensors

Sensor and Communication Shield for Sumo Robot

The semester started last week. Ideally I wanted to have the boards for the new S robot (see “Zumo Robot with WiFi and GPS“) ready in the first week. But our manufacturer was not able to get the four-layer boards with parts populated and delivered in that time frame. Until the new boards arrive, we have anyway plenty of things to cover. One thing is to build a prototype shield to host several distance sensors, nRF24L01+ and Bluetooth transceiver:
