A.s.a. H.'s robots, November 2017

The robots that symbol ground A.s.a. H.'s concepts are modified and changed out frequently, depending upon the experiments that are being run. Currently we are using two nearly identical mobile manipulators and a walker, all on tethers. Each mobile manipulator is a Lego eV3 pbrick mounted on wheels and with an attached robot arm. The 4 eV3 outputs command the 2 drive wheels, a servo motor that raises and lowers the arm, and a motor that opens and closes the gripper/hand. Each mobile manipulator carries 4 sensors connected to the eV3 inputs.  The walker's legs are mounted on a NXT pbrick which commands the 2 drive motors and which also carries 4 sensors connected as its inputs. A set of Vernier sensors are interfaced via LabQuests and can be carried and separately positioned using the two mobile manipulator robots.
