There are any number of ways to perform actions like lifting a floppy basket in the 10 second period after the match ends and power is removed from the transmitter. Any approach which uses stored energy, stretched surgical tubing for example, can work. A motor can be jumpered before a match to wind down the lifting arm from its raised position. The same motor with its leads shorted can then act as a brake retarding the rate at which the mechanism unfolds after being unlatched, to honor the spirit of the rule on energy release rate. The latch may be actively released at the last moment of power availability, or some sort of two stage latch trigger that requires power to maintain the latch once armed in the course of the match might be used. This may not be a particularly smart way to do things, but something related could be made to work. We thought about an after-the-buzzer lift, but it was one of many ideas that were set aside under the pressures of time. I'll be very surprised not to see some teams with delayed lift devices.
