Claw/Landing Gear Accessory

Last crawled date: 2 years ago

There is still a lot discover about the quadcopter use and their use is still limited because of security/safety concerns or technology challenges. Taking in consideration most of the limitations, I assumed that the FV (flying vehicle/quadcopter) will never be designed to get close to a human, especially one located in a crowd and that the weight it will carry has to be limited given by its technological limitation (range, weight lift capability).
Most of the accessories add weight to the FV and make the use of the original landing gear impossible.

In my design, the FV is supposed to carry a servo and attaching pins, ready to accept a number of accessory, such as a revolving light, a claw or a retractable landing gear and many other accessory that can be later developed.
In order to prove the concept, I designed an accessory that replaces the need of the landing gear on the original FV and also adds a claw capable of garbing more than the weight that the FV is actually capable to carry.
- It is easy to be replaced with another accessory that may or may not need a driving mechanism (the servo), by using four pins located on the belly of the FV (flying vehicle).
- There is limited drag caused by the arms and therefore the range of the FV is not affected too much.
- The accessory is easy to be printed and can be done without the need of the supporting material.
- By printing the parts with as less as 15% infill (a feature available by using the 3d printer) the weight is very low.
- The use of the claw is unlimited and can be operated manually through the receiver or its actions can be programmed through an external micro-controller or through the flight controller of the FV.
Update 1:
At the end of each leg, a ball like shape ending has been added in order to make the product more practical:
- the round shape allows a certain amount of sliding when landing in all direction, therefore avoiding flipping over if the landing is not in a perfect vertical direction.
- it is printed with flexible material and with a 15% infill which makes it shock absorber and light;
- by over-sizing this part, it can float if needed to land on water or if needed to be rescued if crashed over water.
