Disadvantages
- Connection is vulnerable.
- By failing element no more possibillity to move box
- Less load bearing
.
Clicking mechanism
Advantages
- Big actuators stay on the ground.
- Lightweight boxes
- Lot of space inside the box
Disadvantages
- 16 actuators per box needed.
- Vulnerable connections.
- needs to 'reset' for change in lay out.
Motors
First normal actuators where considerd but the disadvantages of this type is to big.
To give some indication a actuator with 1200n will:
- Have a size around 40mm*750mm
- Cost around 100 euro
- selflocking 800n
For this principle the best motors would be steppermotors. This motor can be controlled very precisely.
Due to the different atractors in the motor, it can be controlled within a rotation of two degrees.
The second advantage of these motors are their size and strength.
Conclusion
The system where a motor drives a threat is for this project the most promising. It is a simple system which doesn't need complicated elements or extremly powerfull motors. The motors probably best to use are the Steppenmotors, these are very precisely controlable, have a nice 'small' size and are easy to mount. This combination promises to be the winning combination.
