Win the new Arduino MKR1000 32bit Wi-Fi enabled IoT board

The "World's Largest Arduino Maker Challenge" is happening right now through a partnership between, Atmel, Adafruit, Arduino and Microsoft. Here is a video presentation of the context by Massimo Banzi, CEO of The contest will run in multiple phases, the first being an idea submission, by January 15th, 2015. A 1,000 lucky makers with the best proposals will win the newly released Arduino MKR1000 (US only) and Genuino MKR1000 (Outside US) boards that is scheduled to come out on the market in February, 2016. In the next phase, you get to actually…continue reading →

Project 3 – Ball sorter/collector – Step 1

Experimenting potential configurations for a mechanical arm. Motor + screw as actuator. To do: - Stop motor when the clamp grabs something (without crushing it) - Add servos for 2 axis movement The planned steps for this project actually are: - Define platform - Locate the object - Move towards it - Collect - Sort - Locate dumping sites - Unload cargo according to dumping sitecontinue reading →

Line Following Competition Videos

We held our first line following competition last week. We knew ahead of time that right angle turns may cause some issues, so we set up a few to see what happens. We did have some challenges, like you can see here: But at the end we had several clean runs and a winner: reading →

Project 2: Arduino Line following test 3

Test #3 of my Arduino Uno controlled line following bot for the upcoming competition. This test was focused on checking how the bot handles 90 degree turns with sharp corners, line intersections and line breaks. robot uses 6 TCRT5000 IR reflector sensors positioned in a line. (more…)

Project 2: Line following bot – Tests 1&2

This is a very basic line following robot using 4 IR led sensor receiver pairs in a line, continuous rotation servos and Arduino Uno. The wheels are made from beer coasters and I was planning to add a wheel encoder using another IR led / sensor pair at a later stage. The logic is very simple, but works well to test the line detection and the basic movement commands. The next step should be applying a better control mechanism, maybe PID? (more…)

Competition 2: Line Following Robot

General Objectives:

The objective of this contest is for a robot to follow a black line on a white background, without losing the line while navigating several turns on a race course. The robot to complete the course in the shortest period of time while accurately tracking the line from start to finish wins. (more…)

Project 2: Line following bot

Release Candidate Very hard to keep it steady as voltage increases. That's the best speed/stability result I got so far. Now using 3 sensors. The video below has it running at about 6V.
Test 1 With differential steering
This is the project in a very early stage with a regular RC toy steering mechanism. 2 IR sensors to detect change in color and correct direction. It's pretty rough right now and it overshoots all the time. Not the best hardware... No word about software (don't want to blame myself :) )Bare steering logic (RC toy version) (more…)
