I want it capable of entering many different types of robot contests, from Trinity to MOBOT and others. It is being designed to do *everything* like a robot really should. My philosophy says a robot designed to be good at only one task is no better than a dishwasher =P
As a side note, I am keeping a journal documenting more of the specific details. Feel free to check it out if you aren't satisfied with the summarized info I put in this instructable:
Step 1: The Mechanical Design
This is an early concept CAD rendering of it that I made:
I used FEA software to design both the robot arm (see image) and the suspension system. The robot arms consist of multiple servos, and one of them has a controllable gripper. I custom machined all parts using a CNC out of delrin.
I made a video documenting on how I made the suspension system. What makes this suspension system new and unique is that its made from just one single easy to manufacture part!
To give good friction to the custom wheels, I rolled up some sticky rubber and bandsaw'ed a long strip of it. It then went right around the wheel (see images).
The final design is the last image.
This is a video of my robot arm testing below. The robot is drivin by two servos.
