| Erwin Driessens Maria Verstappen Tickle Holland | | |  |  |  | | A skin stimuli generator This small autonomous robot walks on the human body to generate a pleasing tickling sensation. Tickle is equipped with four sensors to be able to detect it's inclination relative to a horizontal plane. Left and right track motors enable it to steer left/right and reverse direction. When it encounters a slope that is too steep, it will steer until a safe level is found, and it will continue it's way. This behaviour is implemented using a hardware finite state machine. Parts and material - polished aluminium cover, aluminium chassis - power on/off switch, connector for accu charger - delrin wheels and bearing parts - hybrid printed circuit board - tilt sensors - two high-torque 5V minimotors - silicone rubber caterpillar tracks - rechargeable batteries weight: 165 g. speed: 1.2 cm./sec runs for 1.5 hours after recharging | |
