John Park posted a cool video of a DIY Delta Robot over at Make. Juan Uberstadt created this robot around an Arduino, we have seen other DIY Delta Robots before but this is the first one that is Arduino based.
“The trajectory is generated by a Pathplanner, which considers the Dynamics of the Structure. Maximum allowable torques in joints and maximum allowable forces in Rods are never exceeded. (The robot moves at maximum possible speed, constrained by max torque and max forces in rods).”
