Lets make robots
Download as PPTX, PDF•0 likes•2,790 views
The document discusses making robots using Arduino. It demonstrates controlling a robot over the internet and building a simple robot that can move forward, backward, and turn using two DC motors. Sensors like light and IR sensors are used to allow the robot to respond to its environment. The document encourages participants to build their own autonomous robot that can avoid obstacles. It provides resources for learning more about hardware programming and Arduino.
Lets make robots
- 1. Let’s make Robots Sudar Muthu (@sudarmuthu) Research Engineer, Yahoo! Labs http://hardwarefun.com http://github.com/sudar
- 2. Why hardware for a software hacker? Fun! #asimijs @hardwarefun
- 3. Let me show you how fun it is.. Demo http://hardwarefun.com/projects/asimijs #asimijs @hardwarefun
- 4. Participate in the demo Visit http://hardwarefun.com:3000 #asimijs @hardwarefun
- 5. Control the bot at stage http://hardwarefun.com/projects/asimijs #asimijs @hardwarefun
- 6. Isn’t that fun? Now let’s see how you can build one #asimijs @hardwarefun
- 7. Anatomy of a Robot Sensors Motors Processor #asimijs @hardwarefun
- 11. Arduino Visual Basic for hardware Treat it like a computer Sensors are inputs Motors are output #asimijs @hardwarefun Photo credit Arduino team
- 12. Demo Let there be LIGHT #asimijs @hardwarefun
- 13. Code void setup() { pinMode(13, output); } void loop() { digitalWrite(13,HIGH); delay(1000); digitalWrite(13,LOW); delay(1000); } #asimijs @hardwarefun
- 15. Demo 2 - Reading sensor data What you need? A Light sensor and a LED #asimijs @hardwarefun
- 16. Reading sensor data void setup() { pinMode(13, OUTPUT); } void loop() { int val = analogRead(A0); if (val > 50) { digitalWrite(13, HIGH); } else { digitalWrite(13, LOW); } } #asimijs @hardwarefun
- 17. Exotic uses of Arduino Making YQL (REST) calls Parsing JSON Interacting with USB devices Interacting with Android phones … and lot’s more #asimijs @hardwarefun
- 18. Simple Moving Robot 2 DC Motors and H-Bridge 2 wheels and a body frame Battery #asimijs @hardwarefun
- 19. Teaching robot to crawl Move Forward Both motors rotate in the forward direction Move Backward Both motors rotate in the reverse direction Turn left Left motor stops. Only right motor rotates forward Turn Right Left motor moves forward. Right motor stops #asimijs @hardwarefun
- 20. Teaching robot to avoid strangers Two IR LED’s. One receiver, one transmitter Both face the same direction Keep transmitting IR waves If receiver receives waves, then there is a obstacle Otherwise keep moving … same logic applies for Ultra sound as well. #asimijs @hardwarefun
- 21. Putting everything together You have your first fully autonomous robot ready. Now take her for a walk #asimijs @hardwarefun
- 22. What’s Next? Do join us upstairs. We are going to implement Machine Learning Alogo to Asimi #asimijs @hardwarefun
- 23. BTW, this is how the demo worked Node.js Server Node Client Admin page User page User page User page #asimijs @hardwarefun
