Honeybee Robotics has been developing a rotary and a rotary-preliminary drill system for planetary exploration. This is a test drill with a power rating of 1000 Watt, whose purpose it to test various drill bits and augers in rotary and rotary percussive operation. It is not optimized for power or mass but rather to acquire qualitative drilling data such as penetration rate, power, and torque, temperature, Weight on Bit, vibration energy and others. In addition, the design of the drill allows it to acquire drill bit temperatures and use pneumatic system (instead of augers) for removing of rock cuttings. The drill is designed to have a 1 meter stroke. In addition to the drill system, we have been developing a matching split vacuum chamber, which is 3ft wide, 3ft deep and 11 feet tall. The chamber consists of two smaller chambers (84 inches tall and 48 inches tall) assembled on top of each other. This allows for additional flexibility if only a smaller chamber is required for some testing. The chamber will be able to maintain pressure of below 1 torr. Maintaining sample temperature will be achieved by closed loop cooling system down to -40C or by using liquid nitrogen that allows a temperature of 77K. The test samples can be varied raging from solid rocks, to loose soils to icy soils and pure ice. The sample holder could also be integrated with temperatures for acquiring of thermal data during drilling process.
