Hello! My name is Ben. I am new to the world of Robotics and super excited to get my hands dirty with a couple of projects semi-work related. Because I am new, I don't want to spend a ton of money on some additional stuff I need to work with the EZ Robot kit.
Does anyone know of a website/source that offers/sells components (e.g. hardware to do linear actuation like a screw-driven linear slide) that works with EZ-Robot stuff.
I remember browsing a website a long time ago but cannot find it for the life of me.
Thanks!
One man built a robot called Bar2D2 which was a robot Bar. It served drinks. It had to get the drinks from the bottom tier to the top one. So, he used a linear actuator. The acuator was nothing more than a 12dc electric caulking gun with rack and pinion. It was really more ecconomical than the linear actuators that you see in the robot dealerships.
Operation- the motor is mounted stationary , usually a worm gear clamp or two works well. And ofcourse the end of the actuator there are drilled holes to attach your mount. And long as both ends are secure the tube won't just spin in place. when the motor turns right the threads push the nut and rod away , when it turns left the threads pull on the nut and tub towards the motor.
This is the actuator iv made for Aegis . It will lift 20 pounds with no problem.
Maybe you could make a smaller one .
Sorry for the crappy pic will post a better one and instuctions soon.

Which leads did you tap off inside the servo. I understand it is the free rotating servo, and I have gutted plenty for model purposes (makes great radar motors on boats!), but I assume you use the signals to stop the servo when it reaches the extents of the pot movement.
Can you clarify a bit more?
Thanks!
