Wall following V0.2

January 27, 2016 Leave a comment

We could improve our wall following code. This time 5 minutes and 20 seconds was enough which seems to be a bit better than 12m40s. (320 sec vs 760 sec) More than 2 times faster with the same walking and turning speed :)

 

Discovery mode and wall following V0.1

Wall following code was developed in 15 minutes :) First test run was completed in 12 mins and 40 secs. You can see the result in a 4 times faster video.

4 legged robot – room discovery V0.1

January 18, 2016 Leave a comment

I have started to develop discovery mode and made few updates:

  • on HW level 3 ultrasonic sensors are mounted to detect walls (or other obstacles)
  • Arduino data transfer code update to send sensor info back to mobile application
  • mobile app. code extension to handle sensor data and initiate turning or stop walking when necessary

From now on we can really use “robot” word because this black thing :) is able to make decisions. Before this time it was “just” an automatic walking machine. Next step can be a new algorithm for proper wall following.

4 legged robot turning

With this update we added a real new capablity. Turning is a base movement for future discovery mode when the robot has to go around in a room and try to avoid obstacles.

Robot typing – hello world :)

Robot typing with dev speed and then faster and faster :) and finally I also tried to do the same with two fingers and with full speed :)

Robot walking with IK – V0.1

Much better walking with fine tuned parameters: better stability, keeping direction and better base code for further developments (IK based positioning could be easily modified for advanced movements like turning or strafing).

 

Robot walking with IK – V0.0

October 14, 2015 Leave a comment

This is rather agony and sliding but please take into account that nothing was fine-tuned, no balancing was used. I just dropped the robot with its new IK walking code on the table :) This is a good starting point and definitely version 0.0…
