I've always liked robots that can move in rough terrain. This time I decided that I will use ready-made chassis modifying it slightly and adding a few additional components. By using a ready chassis I could quickly build a working model and take care of its software. The robot can operate autonomously detecting obstacles in its close surrounding. It can also be controlled via bluetooth using a mobile phone or tablet. The whole electronic design was made based on the Arduino Mega 2560 that is quite powerful. I hope that everyone will find something interesting in this instruction.

Happy coding :)

Step 1: The List of Parts

If you don't have too much time to building your own mobile robot platform you can buy "Robot Smart Car Kit" that includes a chassis, wheels, motors and other mechanical components. To build the robot we will need additional electronics to control the motors and sensors to detect obstacles. At the end we will add LiPo batteries to power the robot and the project will be ready for testing.

Parts needed in this project:

  1. 4WD Robot Smart Car Kit x1
  2. Arduino Mega 2560 x1
  3. BTS7960B Motor Driver (H-Bridge) x2
  4. HC-05 bluetooth module x1
  5. SRF05 Ultrasonic Sensor x1
  6. Sharp GP2Y0A02Y IR Distance Sensor x1
  7. Micro Servo x1
  8. Li-Po batteries: 7.4V 800mAh and 11.1V 1300 mAh x1
  9. Jumper and cables
  10. Nuts and bolts (M2, M3)
<p>How much weight can it carry?</p>
<p>How can i copy the program to the Arduino? need help ASAP :((</p>
<p>If I am walking through a crowd is there a way to keep the robot from following someone else. Can I carry an ultrasonic transmitter or do I need to follow this strategy used by Ben Heck. Do you know if there have been any improvements in Ben Heck's coding since 2012? Could you carry an rf transmitter and additionally put rf receivers, one over each tire.</p><p>https://www.youtube.com/watch?v=tAyWrJoVUbs</p>
<p>Looks like a good example of the vanguard of the next wave of amazing, inexpensive robots -- it won't be long before they are bigger than drones -- as drones become robots, too!</p>
