Introduction
There are already many low-cost wheeled systems existing, but not many legged systems. In Biorob, we want to create an extension to the already existing Rando (http://www.bot-hed.com/). We want to build a low-cost two-legged dynamic running robot. But as this is not as easy as one could think, we decided to build in this first project a low-cost one-legged hopping robot.
Here it is:
Robot Design
The parts were laser-cutted from MDF and glued together. Where there was a movable joint needed, a screw fixed the parts together.
The following parts were used:
Arduino Nano, MPU6050, L298N, 1:48 DC Gearmotors, 3S battery, Prototype plate, foot switch and 1k resistor. Total Price of the components is around 50 CHF.
The linking of the components is the following:
