With some help we were now able to connect the two required motors to the arduino. The hardware works in the following manner: A pushbutton activates the system the relay switches so that the motors are connected to the powersupply the 360º servo starts rotating: it presses the toothpaste out and onto the toothbrush. the […]

Fremdrift Denne uken fikk vi printet ut platene til roboten vår, så vi kunne starte sammensetningen av roboten. Platene ble tegnet i Solidworks og så laserkuttet i trefinér. Ut ifra fysikken involvert, så ønsker vi mest tyngde i toppen av roboten. Dette skaper et større treghetsmoment, som minsker oscilleringene ved overshoot fra motorene. Tenk deg […]

Hello world! its been a long time since last post. and lots have happened. We can start with mechanical. we have bought an rc car to use as a startingpoint. We’re not going to use the parts from the rc-car but we are planning to model parts off the car and create the parts ourselves. […]

first full drawing of the box including the required movements. Besides this small update there is not so much to talk about. Everybody is working on his current tasks.

Progress: Design:  Changes: The mirror will no longer be usable by touch. The touch overlays are just too expensive. We are currently considering which alternative is the best, if its buttons ore some kind of a mouse interface or something completely different. Mechanical: The first parts are finished. After 3D printing them they needed a […]

Today Alvin and arman continued doing some lasercutting. Here is the process of using the lasercutter. The machine we used is an Epilog Laser Fusion M2, with FlexiDESIGNER Software. Before doing any cutting, we start off in a CAD model, in this case Solidworks. Then we saved the file as an .dxf file and exported […]

Toothpaste dispenser The blog will be divided in 3 parts: Movement Parts Materials Movement The tooth paste dispenser is based on a crankshaft movement. The crankshaft movement is an easy, cheap and reliable movement and therefore a suitable solution.  There is chosen to make the movement with bushes and not with bearings. The movement to […]

Progress:  Mechanical / Arduino:  We got the servomotor to move as we want it. As soon as button is pushed, the motor starts moving in steps of on degree, after every degree it will check the connected load cell if a certain weight is reached. If so the motor sets back to zero. This mechanism […]
