Researching three-wheeled off-road robots, asking for info.

Hello everyone,

I've been thinking about building a large off-road robot for a while. I want to make it a fast three wheeler that uses two bicycle tires in the front (bmx size) and a smaller child's bike wheel on a caster in the rear. All of the wheels are going to be independently suspended, with leading arm suspensions in the front and a trailing arm in the back. One design goal is to make it faster than a person can run (roughly 10-15 mph).

This robot was made by MakerDino fellow member of SoR Forum. I loved the design so I wanted to share it with you guys.

Mr Mountain Monster (MMM) was originally named Mr Suspense because his main modification to the Mr Basic kit from DAGU is the suspension and flexible drive system. … Read more

SSS - Servo Suspension System

This is my first experiment with the MakerBot. I am totally thrilled with this machine!!!

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results as soon as possible (still waiting to have my lab back).


I would like to know everyone's opinion on this  :)

Mr. Suspense

Just starting a build blog for the Mr. Basic Challenge II.  When I get some more progress I will post pics and make a robot page.

I'm still developing ideas, but I liked Gareth's work on a suspension system for the original Mr. Basic Challenge, so I'm starting with that.  My suspension will use steel cable instead of polymorph for a flexible power transfer system.  Ultimately,I want to try a four wheel independent suspension, but I will start with the front axis being on one suspension platform and the rear on another.
