Maggie, The balancing robot

Short Description

Maggie is a balancing robot, "segway type".

Maggie participated to the french eurobot qualification 2006, with juste added a few elements for managing the balls. See the story here.

Maggie is capable of passing over small obstacles, detecting avoiding bigger ones, using odometry localisation, carriying beer glasses, rolling overs swing, blinking in the dark ...

Maggie weights 2.8 kg and is 30 cm tall.

Her two brushless gearmotors give up to 3Nm of moment, and up to 1m/s speed.

A gyroscope gives an angle information which is used for maintaining the robot in balance.

The whole robot uses only one microcontroller (Atmel AVR), and a li-ion accu gives about 4 hours autonomy.

The chassis is particularly lightweight because a big part of it is made of PCB (FR4 material). See in the following picture how the elements of Maggie are onganized.

And last but not least, Maggie has an absolutely cool LED Belt! This is the most important feature of this robot.
