Team Toad: Avalanche
Robots > Avalanche > Avalanche 1 |
After a seven year hiatus from building big robots, we decided that Combots Cup 2009 provided the perfect
opportunity to bring the noise back to our fleet.
Since FrostBite was a trademarked BattleBot used in toys, we needed a whole new
name and identity. Avalanche retains the well-known Team Toad plow blade, but
we decided to make it a lifter with arms that rotate around the center of the robot's body.
That allows Avalanche 1 to rotate the blade completely around the robot.
While the rotating arms worked well, the pushing blade made for a poor lifter. Once the opponent was a few inches off the ground, it would simply slip back down off the blade.
But the real Achille's Heel of this design was that there was precious little weight left to make the 18" long arms strong enough to withstand the lateral forces from a horizontal spinner like Last Rites.
- Four 36V NiCad Battlepacks
- Four NPC T64 gearmotors driving 10" foam-filled tires
- One NPC T74 gearmotor driving a two-stage chain reduction for the plow-blade rotation
- One Vantec RDFR 47e speed controller for the drive motors
- One Vantec RSFR 48e speed controller driving the lifter motor
Avalanche competed at Combots IV, losing all four of its fights.
We can claim a Phyrric victory against Last Rites... Last Rites knocked a 3" by 2" chunk
of our plow blade off, but that piece flew inside Last Rites and took out the weapon. So we
did kill the dreaded blade.
- loss to Sewer Snake
- loss to Original Sin
- knocked out by Last Rites
- loss to Brutality
But that hit jammed one of Avalanche's wheels solid. With the wheel stuck, the T-64 motor stalled,
melted its lead wires which then shorted out, and the short fried one half of the Vantec speed
controller. As we tapped out, smoke filled the arena.
Thus as I like to describe the match, "We were doing really well until we caught on fire."
