Wave Nano Gimbal
- Senna Barborini
The initial gimbal has been designed to control exclusively the yaw axis. This assumes that the rover will maintain a certain pitch to the extent and it is not required to implement a pitch control axis.
The gimbal is controlled by a single servo motor placed on top of the wave. It drives a smol gearbox attached to it, a hex shaft mounted to the wave. The hex shaft allows for hex-bored bearing to seat in the carbon tubes for reduced friction. There is a hex-bored bearing on the topside of the support plate which acts as a guide for the assembly.
3D printed components mate to the wave to allow the hex shaft to be mounted robustly. The bottommost component uses an existing wave fastener paired with holes to mount my own hardware.
For the lower support, aluminum extrusion with printed brackets holding its ends to the carbon tubes. The aluminum has another components which acts as a guide to the axis pivot. This support is responsible for holding the weight of the assembly. It is integral that the printed bracket on the carbon and a firm hold; not susceptible to vibration induced shifting.
The brackets have its seems tangential to the ends of the carbon tube so it may be pulled out easily.
