Forklift's Revenge
Weight:79.8kg
Drive:2x120w wheelchair motors, 70A speed controller
Weapon:Spiked Chain (used for traction where required) passive forks
Armour:MDF + Aluminium

This new robot is "Forklifts Revenge" We wanted a robot which was:

  • Better than the last one
  • Heavier than the last one
  • Different weapon (but could still be caled forklift)
  • Easier to Drive
  • As un-weggie as possible (although this is difficult given the spiked chain needs a slope to be effective)

We used the basic chassis from forklift (its the bit I spent the most time on, and wasn't kept together with cable ties) but removed the fork runners, and extended the subframe, so that we could attach the armour plated directly to it, rather than the silly clamshell design we had last time

The control systems were shrunk to a quarter of the size, and tidied up. We kept the old microswitch setup, so that we had backup if the speed controllers failed. With this setup, we could loose both speed controllers (weapon+drive) and still have a functioning robot (change to switched drive, and run the weapon continously)

I have been playing with this robot in the garden, and its a bit of a beast. The spiked chain will pick up all kinds of large household appliances.

We still have yet to hear from Mentorn after the auditions.... 360 robots this year, and dispite a vastly improved robot, I have no idea how we will do.

If we get through.... I'll probably extend this site, and I might scan in some photos!
