How exactly does those obstacle sensors work? Seems for me that the robot stops when the sensor senses something, and then the robot turn either left or right before it continues walking. Does the obstacle sensors that’s used on that robot make the robot turn like, 45 degrees before it continues walking, or how does it work?
Although I don’t have the robot myself, and have not played with the program in question, I believe that that motion is a standard routine in the PowerPod program, as referenced in the tutorial] for the AH-3R robot. The controller’s “X” button activates “attack mode”, which I believe is the bit where it rears back on four legs while waggling the other two (at 1:25 in the video clip), and the square button activates “Learning to fly” mode, with the bot supported on four legs and the other two “flapping” like wings.
This is controlled by an Atom 28 and an SSC-32 servo controller. The program for the Atom is written for you with the PowerPod hexapod control program generator, so there is no programming required to get it working right away. See this tutorial. lynxmotion.com/images/html/build99b.htm
The second video is of a robot that apears to be all pretty much custom electronics. I don’t know anything about it.
Awesome. There’s no words besides awesome to use to explain this. Well, maybe fantastic
Does the SSC-32 Servo Controller know how to make the robot move diagonally? Does the servo controller use the forward- and left-“settings” and chose what would be inbetween?
The SSC-32 does have a built in 12 servo hexapod sequencer engine. This style robot has two servos per leg and can only be built in the “inline” fashion. The controller can automatically move all of the servos involved in walking with only some very simple commands being sent. Walking speed and direction, as well as body ride height and leg lift can be done easily. The servo controller can also do it’s normal thing on any of the other servo channels at the same time.
For the 3DOF hexapods the movements are calculated by a Basic Atom processor that sends the commands to the SSC-32 for all the movements. It can walk in any direction (translation) and it can rotate in place (rotation) but the cool thing is it can do both at variable rates at the same time.
This robots could be use as mine sweepers, right? Add a metal detectors around its feet just to be sure were not to stand, and have the lynxmotion robot arm on front sweeping the area in the middle of the robot for mines.
Add some painter to the arm too so it could mark the area containing metal/mines.
Over to something a bit more advance. On most of the clips on youtube that I’ve seen, the robots has been walking on surfaces like wood/concrete/lawn etc… Picture the robot walking on a surface like on this picture: i80.photobucket.com/albums/j171/ … log000.jpg
As you’ll see on the following youtube link, the robot avoids the area with a surface lower than the one walking on. youtube.com/watch?v=Pdj6R0UTB8Y . Back to the picture, will the six-legged robot put its feet right in the hole and get stuck, or would it find another place to put its foot? I guess it couldnt be too hard to assign one of the joysticks on the PS2-controller to controll one single foot at the time for more complex walking. Moving one foot at the time would take alot more time though. When you guys use your robot, do you use easy-mode floors to move on or do you let your robot do more interesting tasks?
Could probably use something like sonar to decide where to put the feets.
I would so love to have one but I have to wait a few more weeks before I can get one.
