- Autonomous control with python program.
- Used of the six proximity sensors

PID control
In this video MRPi1 robot is controled by two PID controller. The PID controller calculates an error values between motors encoders and desired value (orientation and distance).
- Orientation control
- Distance control
The speed profile :
- Trapezoid profile with 3 parts : acceleration, constant speed and deceleration.
Encoders specification :
- Magnetic encoder,
- Resolution : 12 ticks/tr

Control with a simple web interface.
New video, control the MRPi1 prototype with a simple web interface.
- Smartphone controlled,
- Wifi access point configuration with hostapd.
- Web interface (forward, back, turn and stop)

MRPi1 speak.
MRPi1 robot can now speak about temperature and his battery level. This information is asked by TV remote control.

Autonomous Obstacle Avoiding.
Now, MRPi1 manage obstacle avoidance autonomously. On this video, the robot was programming with python language.
The robot detects obstacle with its four infrared proximity sensors.
