When you have built the default design you are ready to change it. We will post some interesting examples here. Above you find two quick examples. One has a smaller arm that gives a more compact workspace but also higher forces and resolution. The other has a hand-made arm fabricated on a traditional wooden lathe.
Changing the following parameters (see the kit page) is a good way to explore too:
"max_linear_force": 12, N "max_linear_stiffness": 5000, N/m "max_linear_damping": 8, N/(m/s) "g_constant": 9.81 m/s^2; 0 = no gravity compensationEspecially the stiffness; if you reduce it you can in some sense emulate other devices, e.g. the Omni has about 800 N/m. If you increase it too much you might experience instability (vibrations).
