Oh, ok you spelled "hold" wrong, lol. how about a test tube to hold the water? the 1kg doesn't include the water, does it? This is not a difficult project, i'm sure you could design and built it yourself

Please provide more details

do you just want the chassis of such a robot?


Yes it is easy, and as Trumpkin said, you could build it yourself
Check out the Roboduino, Arduino-compatible board!

I think the $50 robot weigths less then 1kg. You could use that. If it is too heavy change the battery.

ok guys i really appriciate that you are helping me but hear is the requirements:

1.)Design, build, and demonstrate a robot which will wash a residential double-hung sash window autonomously, that is, without human intervention beyond placing the robot on the lowest window pane and turning it on, or under remote control of an operator “inside” the “ building”.  This device should be able to clean both the inside and the outside of a double-hung sash window, but this contest will be based on cleaning the outside of the window.  A large scoring bonus will be given to those teams who are successful in completing any substantial part of this operation autonomously.

2.)Requirements:

   1. Once placed on the window glass and turned on Winrobo must maintain itself on the specified vertical residential window and move around as necessary on the surface without assistance.  Winrobo may touch or make use of the wood, vinyl, or aluminum surface surrounding the glass if desired, but may touch only those surfaces within 25 mm of any part of the (clear) window pane being cleaned.  Winrobo may not touch the outside or the inside of the building wall or the trim area around the window (either inside or outside).
   2. If operating autonomously, Winrobo must find the edges of the window on its own and complete its cleaning process—it may not be pre-programmed to only clean the one size window specified for this contest.
   3. If operating under remote operator control, the following rules apply:

      a. The controller and the robot must be connected by an umbilical cord which carries only control signals.  The control box may not include any batteries or auxiliary power.  Radio control is not permitted.

      b. The umbilical cord must be connected to the robot through a commercially-available 9 or 15 pin sub-D connector

      c. The umbilical cord cannot be more than 2 mm in its thinnest dimension so that it can pass through a crack above or below a closed window.

      d. The umbilical cord must be able to withstand repeated clampings between the moving and stationary parts of the window without damage.
   4. Winrobo must be provided with a safety cord which can be closed into the window frame or otherwise secured in a non-marring way to the building wall, and which will prevent Winrobo from falling more than two feet below the elevation of the middle of the lower window pane in the event of a malfunction.  If an umbilical cord is used it may NOT also be used as the safety cord.
   5. While on the window Winrobo must clean the window by wiping off the dry erase ink used to simulate dirt on the window.
   6. Winrobo must carry within itself 50 ml of water, which will simulate the cleaning fluid which would be used in the final design.  This water must not leak out or be pumped out of the device during testing.  It will not be used in actual cleaning.
   7. Winrobo must /be capable of cleaning the entire window pane on which it is mounted.  It may not leave some areas which it cannot clean (such as under attachment points on the window pane if, for example, immovable suction cups were used to hold Winrobo to the window).
   8. Winrobo should be capable of moving from pane to pane on the window on its own or under operator control from inside the “building”.   A major scoring bonus will be awarded for successfully completing the transition from lower to upper window pane.
   9. Winrobo must be battery powered.  The maximum battery voltage allowed is 24 Vdc maximum.  The battery must be rechargeable.  Winrobo must be capable of cleaning the outside of the test window without needing to be recharged.
  10. Winrobo must have a safety system on it so that if the battery voltage drops below a “safe” level  it will go into a “safe” mode where it stops cleaning and simply clings to the window pane while turning on a warning light.  Team members must be able to describe this system to the judges as part of the qualification inspection.
  11. When Winrobo is finished with a window it must turn off all cleaning operations, go to the lower left-hand corner of the lower pane as viewed from the outside of the “building”, and turn on a signal light to indicate finished status.
  12. The maximum allowable time for Winrobo to clean a window (both panes on the outside of the window) is 5 minutes.
  13. Winrobo must be capable of being packed, fully assembled and ready to operate, inside a box with the inside dimensions of 600mm x 800mm x 300 mm high.  The 300 mm dimension is the horizontal distance between the window pane and a vertical plane tangent to the point of Winrobo which is farthest from the window when Winrobo is in the operating position.
  14. Winrobo must not weigh more than [1 kg] when fully charged with fluids.
  15. Winrobo may not damage the window or window frame in any way.


what you think about this.

So it sounds like you have to clean BOTH sides of the window without human intervention, right? some kind of suction thing would be good (obviously). Maybe you could use parts of a vaccum cleaner for the suction part, and cushioned rollers connected to servos to roll around the window. you need some light batterys like Li-ion. can this thing be plugged into an outlet?? that would make it much easier to have vaccum cleaner parts. OR maybe it's possible to power the whole thing from the outlet, that would save you the weight of batterys.

Hey guys!
     Ok, your going to need a light matrieal, this mans you robots not going to be to fancy. Also, use small wheels, they have more torque, and the wheels will be lighter, also, and this is sorta stupid, use something that shoots water, like maybe even a water gun!
