I designed the entire robot using CAD software.
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.
