Physics & Robotics

3. mechanism with minimal components which can be used to transmit or redirect mechanical power through a system
5. of Energy natural law stating the total energy in an isolated system remains constant over time unless external forces act on the system
7. type of wheel and axle with a disc-shaped wheel with teeth protruding outwards radially around the circumference of the disc; one of the most common types of gears in a robotic system
10. used to achieve a high gear ratio or when the engineer needs the input and output axle of a gear train to remain co-axial, also known as epicyclic gearing
12. cylindrical core with a continuous helical feature wrapping around it
13. round disc—the wheel—mounted with a cylindrical component of smaller diameter—the axle
14. rigid body, or beam, which pivots around a fixed point, or fulcrum
15. rotationally symmetric and conical, with the teeth meshing along a 45-degree angle between the two perpendicular axles
16. amplification of input force achieved by using a tool, machine or mechanical device; calculated by dividing the output force by the input force

1. type of gear where two spur gears with a different number of teeth have been fused together to rotate coaxially
2. flat, sloped surface with one end higher than the other, otherwise known as a ramp
4. series of gears designed to achieve a specific output, usually one which could not easily be achieved with a single pair of gears
6. straight bar with teeth designed to mesh with a spur gear
8. arrangement of rigid bodies, or links, which pivot or slide relative to each other to transmit and redirect power
9. number of helical threads per linear distance of a screw
10. wheel on an axle or shaft which has a groove to allow a cable or belt to pass over the pulley
11. single, triangular rigid body which is thick on one end and tapers to a point
13. type of screw; helical gear meshes with a spur gear and transfers rotational power between a pair of perpendicular axles
