We provided a holonomic omnidirectional cart using a universal wheel with the power-assist function and put it into practical use as a meal delivery cart. Even if the cart weighs about 700 kilograms, it is easily operated as a manually operated lightweight cart. This report gives an overview of the new product, measures for enhancing operability, a handle sensing force in 3 directions, measures to reduce vibration during universal wheel driving, and ways to improve universal wheel durability.
