Evaluation of the power deficit of elderly people during stair negotiation: Which joints should be assisted at least by an exoskeleton and with what amount?

Abstract: Abstract Climbing stairs can become a daily obstacle for elderly people, and an exoskeleton can assist here. However, the exoskeletons that are designed to assist stair climbing are actuated in different ways. To find a minimal actuation configuration, we identify the assist phases by evaluating the power deficit of 11 healthy but weak elderly people (72.4 ± 2.1 years; 69–76 years; 1.67 ± 0.10 m; 74.88 ± 14.54 kg) compared to 13 younger people (24.0 ± 1.8 years; 22–28 years; 1.74 ± 0.10 m; 70.85 ± 11.91 kg) in a biomechanical study and discuss moment characteristics. Three-dimensional kinematics and ground reaction forces were collected, and kinematics, kinetics, and power characteristics of each subject for ascent and descent were calculated using inverse dynamics. Significant differences for power between both groups were assessed with statistical parametric mapping method using dynamic time warping. During ascent, the largest significant power deficit of the elderly subjects occurs in the single stance phase (SSP) during pull-up in the knee joint. During descent, significant mean power deficits of 0.2 and 0.8 W/kg for the highest deficit occur in the ankle joint in the beginning of the SSP and also in the knee joint in the same phase. Therefore, an exoskeleton should address the power deficit for knee extension (ascent: 1.0 ± 0.9 W/kg; descent: 0.3 ± 0.2 W/kg) and could assist the ankle during ascent and descent by an additional plantar flexion moment of 0.2 Nm/kg each.

Automatic stair climbing firefighting robot

Abstract: The utility model discloses an automatic stair climbing firefighting robot, which comprises a crawler-type automatic walking base plate, a firefighting system, an emergency ejection automatic holding device and a control and image transmission system, wherein the firefighting system, the emergency ejection automatic holding device and the control and image transmission system are arranged on the crawler-type automatic walking base plate; the crawler-type automatic walking base plate comprises a battery pack, a supporting base plate, a crawler driving system and a stabilizing and anti-tilting mechanism; the battery pack is arranged on the supporting base plate; and the firefighting system comprises a foam tank, a foam liquid inlet pipeline, a water tank, a foam proportion mixer, a foam mixing pipeline, a water pump water inlet pipeline, an ejection pipeline, a firefighting water pump, a jet orifice, a jet device, a first water pump water outlet pipeline, a second water pump water outlet pipeline and a water pump power input device. Due to the adoption of the crawler-type automatic walking base plate, normal walking, retreating, steering and on-site steering functions can be realized, and the automatic stair climbing firefighting robot can walk up and down ordinary building stairs and railway stairs safely and smoothly.

Wheel and track combined stair climbing cargo transporter

Abstract: The invention discloses a wheel and track combined stair climbing cargo transporter. The wheel and track combined stair climbing cargo transporter comprises a first frame and a second frame which arearranged vertically as well as a first driver and a hinging assembly which are arranged between the first frame and the second frame in the driving direction of the cargo transporter, wherein two endsof the first driver are hinged with the first frame and the second frame respectively; a first wheel assembly enabling the cargo transporter to drive on the ground is arranged below the first frame;a track assembly is arranged on the second frame, a second wheel assembly connected through a position adjusting assembly is arranged below the second frame, and the first wheel assembly and the second wheel assembly are arranged forwards and backwards in the driving direction of the cargo transporter. The cargo transporter has the advantages as follows: a flat ground driving mode driven by a wheel train or a stair climbing mode realized by a track mechanism can be selected according to actual demands when cargos are transported upstairs and downstairs, meanwhile, two functions of high-speed driving on the flat ground and stable stair climbing are realized, and the problems that existing cargo transporters cannot climb stairs and have poor maneuverability are solved.

Wheel and belt combined type transport vehicle capable of climbing stairs

Abstract: The utility model relates to a wheel and belt combined type transport vehicle capable of climbing stairs, which belongs to the technical field of a transport tool. The utility model is characterized in that the utility model is added with two rolling belt components on the basis of a two-wheeled vehicle, each roller is installed on a roller frame through a wheel shaft, and the roller frames are connected with support frame connecting rods; a rigid inner track is wound on a roller set, and the rolling belts are installed below a vehicle frame through the support frame connecting rods. The utility model not only solves the problem of stair climbing transport, but also climbs steadily without bumping, and is widely used for travel, residential houses, engineering vehicles, etc.
