We've heard that omnidirectional driving can be done with omniwheels by turning them at an angle, but some team-mates don't think that this is necessary. We've had trouble finding internet resources that would give us an explicit yes or no answer (using straight omniwheels in a normal tank drive configuration to strafe; can or cannot be done), so we were wondering if anybody on this forum could settle the matter for us.
For a final bit of clarification, our omni-wheels would look like this = =, and we want to strafe. Sorry if I've repeated myself, I just want to communicate clearly. Please include any references so that we may refer to those as well.

You might like to take a look at Youtube for the varying setups and capability of each. Some are helpful ones may be

Airtraxs sidewinder uses the meccanum wheel

Eric Allards set up uses fixed centre wheels and combination of omni-directional wheels.
Boththe above mount wheels in-line
The typical omni-directional wheel solutions use a either a quad set up or triple holonomic set-up, however for muilti-directional driving the wheels need to be mounted at an angle (offest) to each other for driving. You will find many videos on Youtube of examples of this.
Good starting point in seach by on YouTube by "rotacaster" and or other keywords such as holonomic, Robotics, omni-wheels etc.
