Mike's project to build a quad bot.
Calvinbot is my project to build a quadroped robot. Eventually the goal is to compete in the Robogames Mech Warfare competition.
Calvinbot's design is based on Dynamixel digital servos, with the Arbotix (Arduino-derivative) microcontroller as the "brain." It will communicate via Xbee radio to a laptop using the BioloidController and PyPose code: 
I'm fairly new to programming and robotics--so this is an opportunity to learn as I go!
Update 2/1/13: Assembled all 4 of the robot legs with Tiffany's help. Have done some desigining of body plates in Inventor and will be laser cutting soon! Here's the current design:
Update 3/4/13: Calvinbot is assembled and code loaded! Here is a video of some first steps: http://www.youtube.com/watch?v=MoLM-EFDYfo&feature=youtu.be Currently the robot is recieving commands from the laptop via "test drive" mode in the Pypose software. Still lots of work to do to improve the gait and put together some of my own control code. Also, thinking of shortening it to Qalvin (Questionable Acronym aLlowing Virtually Indiscriminate Naming...)
Parts already obtained:
Dynamixel AX-12A digital servos from Robotis
Various brackets and connectors from Robotis
Battery-powered Airsoft gun
Wireless IP camera (D-link)
Voltage regulator for camera
Laser-cut ABS leg pieces
Laser-cut ABS central frame pieces
Wish list/build list:
Gun and camera mount system
Mech warfare pressure-sensitive plates
Solid-state relay circuit for Airsoft
Installed necessary programs and libraries: Arduino environment, BioloidController, Pypose, Pymech, Python, NUKE, etc..
Successful communication established: laptop-->XBEE-->XBEE-->Arbotix-->turn a servo
Leg design completed in Inventor
Body plate design completed in inventor (2/1/13)
Body laser cut, assembled, and robot is up and walking with Pypose/Nuke (3/4/13)
Partial To-do list
Design and laser-cut gun and camera mount
Fine-tune reverse-kinematics "library"
Adapt PyMech code to command Calvinbot from laptop
Learn much more Python/Pygame so I can write my own control program!
