Hi,

I've modified your script a little to do what I believe you want it to do. I've commented the parts of the code that modify the viewpoint. Let me know if this isn't exactly what you are looking for.

import viz
viz.go()

viz.mouse(viz.OFF)

viz.add('tut_ground.wrl')
Wheelbarrow = viz.add('wheelbarrow.ive')

#Get handle to main viewpoint
view = viz.get(viz.MAIN_VIEWPOINT)

Wheelbarrow.translate(0,0,6)

MOVE_SPEED = 10
TURN_SPEED = 360

def mytimer(num1):
	#Move wheelbarrow using arrow keys
	if viz.iskeydown(viz.KEY_UP):
		Wheelbarrow.translate(0,0,MOVE_SPEED*viz.elapsed(),viz.RELATIVE_LOCAL)
	elif viz.iskeydown(viz.KEY_DOWN):
		Wheelbarrow.translate(0,0,-MOVE_SPEED*viz.elapsed(),viz.RELATIVE_LOCAL)
	if viz.iskeydown(viz.KEY_RIGHT):
		Wheelbarrow.rotate(0,1,0,TURN_SPEED*viz.elapsed(),viz.RELATIVE_LOCAL)
	elif viz.iskeydown(viz.KEY_LEFT):
		Wheelbarrow.rotate(0,1,0,-TURN_SPEED*viz.elapsed(),viz.RELATIVE_LOCAL)

	#Create transform from wheelbarrow
	xform = viz.Transform(Wheelbarrow.get(viz.MATRIX))
	#Move position up 1 meter and back 5 meters
	xform.preTrans(0,1,-5)
	#Apply position of transform to viewpoint
	view.translate(xform.getTrans())
	#Have viewpoint look at wheelbarrow
	view.lookat(Wheelbarrow.get(viz.POSITION))
	
viz.callback(viz.TIMER_EVENT,mytimer)
viz.starttimer(1,0,viz.PERPETUAL)
