Last night, i finished rebuilding the electronics board, and i could assemble a functionnal version of R.Hasika. Things are still not yet there, but there was enough stuff to try a simple algorithm.

So i reassembled the robot, and once things were mostly in place i got this :

Anyway, i could use the Arduino board to control the motors, and the contact switches i the front did work. I was able to get the robot to execute a simple obstacle avoidance algorithm, as seen in this video :

After the video, i did some other work on the robot (adding a distance sensor, a power button, LED), giving the followig result :

• add a diode, to prevent the motors from beeing powered when plugging the USB cable,
• print parts to hold the sesor and the power swich,
• deciding where to put the LEDs,
• put a divider on the TX output of the arduino then connect it to the RX of the pi
• connect the Rx of the arduino to the Tx of the pi;
• bring power to the pi;
• connect the battery output to an arduino analog pin to monitor battery level;
• put the motors rotation sensor in place;
• print a cover.
