Last week I showed the chain driven system I added to Hawi, which could move up and down, as well as to left and right. To try and make it useful, I've attached a dry-erase marker to it, with a longer term goal of making it draw something. Until I get there though, I need a way to apply the marker to apply just the right amount of pressure on the dry-erase board (the desktop tower in video is just a stand-in for the dry-erase board for now) The marker assembly consists of a spring and two switches. The two switches are not quite at the same level, on purpose, to detect the 3 possible cases: -the two switches are off: not enough pressure. Move forward. -only the first switch is on: pressure is just right. Stay there. -the two switches are on: pressure is too much. Move away. http://www.robidouille.com https://www.google.com/+Robidouille

In this video I'm using back EMF to know when the rails reach their mechanical limits. I took some drawer slides, and used them to create a cursor which can move left/right as well as up/down using 2 DC motors and a chain drive. First the cursor moves left, then when it cannot go any further, it starts going up. Again when it cannot go any further to moves right, then down, and left again. And so on, indefinitely. I didn't put any switches or buttons to detect the end of a run, it's all done using back EMF. It detects when the motor stalls essentially, and changes course. It's all done using an Arduino micro-controller and L298 H-Bridges. Back-EMF circuitry is explained here: https://robidouille.wordpress.com/2009/09/20/back-emf/ I'm using my back EMF library to do this: https://github.com/robidouille/robidouille/blob/master/Arduino/libraries/BackEmfMotor/BackEmfMotor.cpp http://www.robidouille.com https://www.google.com/+Robidouille

http://www.robidouille.com Danger Monkey is back. Last time I showed Danger Monkey it was moving on my test setup. You can see that video on my website or my youtube channel This time I went to test it on-site at the office. This wooden rail makes a circle around the office and is around 9 feet above the ground. Needless to say, falling off the rail is not a good idea.

http://www.robidouille.com This new robot is called Danger Monkey. Its goal is to be able move on a horizontal wooden 2 by 4 stud. To complicate things a little however there are obstacles as you can see, and they that need to be avoided. I've tried several designs, some with wheels, and others with arms. My 2 arm version is working best so far. I'm using an Arduino as microcontroller. The servos are cheap Hitec HS322-HD. Each arm has 2 lever-switches to detect pressure in front and below. This actually comes from a challenge at the office, where we have a much bigger version of this that goes around the ceiling of our building. Next step is to see if it works there.

http://www.robidouille.com Jodi is my first attempt at the HBRC Challenge. For Phase1 it has to stay on the table. As you can notice it has more sensors than necessary for this. They are meant to be used for Phases 2 and 3.

http://www.robidouille.com Hawi has 4 motorized wheels. Each wheel has it's own DC motor and a servo that controls it's orientation. So it can turn like a car. But also turn all it's wheels and move sideways. Planetary gearboxes on the motors allow for high torque and precise control, in spite of it's weight. And finally setting the wheels at 45 degrees allows Hawi to spin. Hawi is remote controlled for now, but the goal is to make it autonomous as soon as possible.
