Die Teams der European Space Elevator Challenge 2012
We are interested in the space. We feel a dream and romanticism in the space. Space Elevator is one of means to go the space easily, and we may be able to make it.Drive system:
Our climber has two drive modules, and the one module have two drive rollers linked one motor. The module also has three brakes. A motor brake, a ratchet brake for emergency stop against unanticipated fall, a dynamic brake for test of a regeneration brake.
And the module has rope bending mechanism. It gives the climber more friction force by bending rope.Energy supply:
Just battery. one module has one battery, it is 22.2V, 4500mAh Li-Po battery, so our climber has two batteries.Electronic system:
Both autonomous control and remote control. We can choose one control. If we choose autonomous control, the climber will work with the position recorded by rotary encoder. If the climber slip, it will use the bending mechanism and reduce slip rate.
The space elevator make us go to space more easier. Then everyone may be able to use Space environment. Space Elevator is an undeveloped technology. To make climber is so difficult therefore we want to challenge it.Drive system:
There are two drive modules. There are two each drive roller and the driven rollers in one module. Drive roller and the driven roller is a face-to-face. The two drive modules are connected in the frame. The frame is equipped with a battery and control board and the payload.Energy supply:
Energy supply is a lithium-polymer battery.
Specification: HYPERION 6S, 22.2 V, 5000 mAh
Self-control using a Arduino. The wireless communication with the climber will use the Xbee module.
A space elevator is helpful to people and there is a dream.Drive system:
Six-wheels drives, pressed by a springs mechanism and run on two motors.Electronic system:
Our climber detects the goal by touch sensor or ultrasonic sensor. The climber has rotary encoders and detects slip and distance. The climber also has PLC.
The space elevator fascinates us, because it is pioneering technology which has the potential to carry both people and payload much cheaper and safer to space. Thus, the space elevator could be the basis for many other innovations and could advance mankinds exploration of space.Drive system:
Our Climber is driven by a brushless motor with a maximum power of 5kW. The transmission is done via a single-stage chain drive on a commercial rubber and rope form custom wheels.Energy supply:
We estimated the weight of our Climber during the design phase with our CAD Tool. Then we calculated the required battery capacity using the difference of potential energy of the climber between ground and the target height and the degree of efficiency of the whole system. The degree of efficiency of the motor, motor-controller and gear were estimated based on datasheets and experience.Electronic system:
- Push button up and down
- Possibly supported by ultrasonic sensors
- Several temperature sensors, e.g. for brake
- Speed sensor and distance sensor based on light frequency measurement
To be able as humans to achieve the unachievable.
Also to discover new technologies.
