Wouldn't high suction give you better traction (ie. by adding an additional downward force to the force of gravity) and hence mitigate any disadvantage of low weight ?
Also with sufficiently well-controlled motors you should be able to optimize suction and drive, say to minimize power consumption or maximize speed/vacuum power.
- kordless 12y agoOr better, modulate the suction based on your desire to adjust course. Suck more on the left, less on the right, and heave on the rudder for a hairpin. :)
- jonnydark 12y agoIt'd give somewhat better traction but at the same time you increase the likelihood of stalling your motors. How does the machine know if the motors are stalling because there's something jammed in the wheels or because the vacuum is sucking stuck to the floor? You can design algorithms or sensor mechanisms to try and determine this and also tune the motors but now you have even more problems!
- arethuza 12y ago"Wouldn't high suction give you better traction" Reminds me of the F1 Brabham BT46B "fan car" that sucked itself down to the road using a large engine driven fan at the back of the car: http://en.wikipedia.org/wiki/Brabham_BT46#Brabham_BT46B.C2.A0.E2.80.93_the_.22fan_car.22 http://en.wikipedia.org/wiki/Brabham_BT46#Brabham_BT46B.C2.A...
- IshKebab 12y agoThe tank treads are sprung, so I think it actually just sucks the sole plate onto the ground rather than the tracks.
