Off-road

A long time ago (15 years to be precise) as an undergraduate I messed around in a robotics lab and even participated in a robotics competition in France. Te revive … Read more

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).

Bigger version of the DAGU 6wd Wild thumper

Hello i am thinking of building a bigger version of the dagu 6wd wild thumper. a big one that can tow and go over larger obstacles much like the smaller current one. The motors i have selected to use are winshield wiper motors and will be powered by either a custom build lithium polymer battery pack (putting a bunch of  3 cell 2200mah batteries in parallel) or a car battery. I would probably go for the lithium polymer as they have a greater energy density.

 

What inspired me

My first full project. This is a suprisingly capable little robot built on top of a R/C crawler chassis I found at a local thrift store. It can handle hills and … Read more
