Actuators and threads
For this principle we use normal actuators. To give some indication a actuator with 1200n will:
- Have a size around 40mm*750mm
- Cost around 100 euro
- selflocking 800n
Advantages
- Small engines needed
- Simple principle
- Stabil/solid connections
- Big differences between neigboring elements possible
Disadvantages
- 4 Engines per box needed.
- Weight system
- Lot of chance of failure due to the number of engines.
.
Gearing in between
Advantages
- Only 2 engines per box.
- Less weight due to less engines.
- Individual controlable
- Big differences between neigboring pistons possible
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
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.
