Hemisson – mobile autonomous robot

Hemisson – mobile autonomous robot

The mobile autonomous robot Hemisson was designed specifically for teaching and education. Equipped with several infrared proximity sensors, a PIC16F877processor at 20Mhz, a ground line sensor, a buzzer, 4 LED and an infrared receiver, the Hemisson mobile autonomous robot is well adapted to standard curriculum of mobile robotics. You can then program detection algorithms, obstacle avoidance or line following behaviors.

The mobile autonomous robot requires no assembly and has a flexible structure that makes it less sensitive to shocks which can be an asset in the context of a class on robotics. The Hemisson robot, as all the robots created by K-Team, is recognized for its quality.

Programming the Hemisson mobile autonomous robot

The robot programming is done via the serial port. The Hemisson robot is programmable by Visual Studio C ++, Matlab or other program accessing the serial port (these programs are not provided). For enthusiasts who want to go further, the firmware of the robot is open source, it is possible to modify and adapt it with the CCS C compiler (not supplied) and the Hemisson Uploader (supplied).
