The Mantis Walker is a two servo walking robot. I've included the build instructions as a PDF.

It uses an ultrasonic sensor to detect and avoid obstacles in it's path as shown in this video:

Print out the body, the battery holder and the legs and follow the instructions to build.

I have included the Arduino sketch and the wiring diagram for the electronics is in the PDF.

sensational how well this little bug walks with just two servos, I can't belive it! Need to print this soon.

hi robotshed, is it good to use jumper wires to connect in arduino instead of creating a circuit in arduino uno? thanks

Hi RobotShed,
I have built the Mantis but I haven't been able to get it to work yet. Would it be possible to upload the NewPing library you used.



I've uploaded it. The source was on google code but seems to have moved.

Great idea!
But is the 9V battery powerful enough for two servos? A 2 cell LiPo might be better?!

I made the battery holder as a separate module so you can replace it with LiPo for more mAh. I wanted to keep the total cost under AUD$15 and a 9V battery is very cheap and gives plenty of power for my kids attention span :-)
