Docking for battery charging

Circular hexapod omni-bot battery charging.1

Hexapod identifying its battery charging spike and then sitting on it, (oooh painful!). Just one robot shown at Singapore’s Nanyang Technological University inter-faculty research competition in 2003 where Frank’s students won 1st prize in the robot division

Charging system with robot shown reaching 6% charge

…after sitting on the battery charging spike, the charging system, which can also discharge the battery if necessary to put the battery in a known charge state, shown on the left, measures the battery status and starts to charge the hexapod on-board battery. The charging system integrates the electrical current with respect to time to indicate the charge status and this is shown as a percentage on a visual display. all done by Frank’s students as their Final Year Project
