project G:Different systems
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.
