Grumbler is a programmable autonomous mobile robot for hobbyists and researchers.

Being equipped with sensors, actuators and processor, Grumbler is able to do many amazing things. It can, for example:

• Detect direction to the sound
• Detect movements
• Avoid walls and other obstacles
• Avoid stairs
• Support cruise-control
• Measure the distance
• React to changes in light and noise
• Overcome obstacles up to 2-3 cm in height
• Fall asleep, if nothing interesting happens
• Detect falls and kicks and react accordingly
• Detect turnover
• Turn off TV (due to egoistic motive :-)
• Become hunger
• Indicate its status by LEDs
• Produce various sounds depending on stimulus

Moreover, Grumbler's hardware is ready for voice command recognition, step-by-step JTAG-based software debugging and much more.

• Motor power control based on pulse-width modulation
• Power saving modes*

Flexible research platform:

Marvelmind Grumbler is not only a fully assembled and ready-to-run robot, but also a flexible hardware and software platform for experimenting. You can easily hack our code because it is open-source and full of comments. We also offer How To Start examples that would guide you when you start teaching your Grumbler new skills.
