tutorial videos earlier, and simon gave me a lesson. i ve actually got a shot? all right. you have a lot of faith in me, more than i have in myself. thank you. and.go. i dropped the mortar, sorry. what if i cheat a little? i will do two. that s it, see, i did two in one. can the robot do two in one? no. i ve got five more left, how many has it done? no it hasn t! is it done? then i won. one thing the robot can t do is refill itself, can it? the brick don t fit. hold on. all right, push all these along. done! this is tougher than i thought, and it actually takes a 2 year apprenticeship to learn the trade, so for a robot
and simon gave me a lesson. i ve actually got a shot?! alright. you have a lot of faith in me, more than i have in myself. thank you. and.go. i dropped the mortar, sorry. what if i cheat a little? i will do two. that s it, see, i did two in one. can the robot do two in one? no. i ve got five more left, how many has it done? no it hasn t! is it done? then i ve won. one thing the robot can t do is refill itself, can it? the brick don t fit. hold on. alright, push all these along. done! this is tougher than i thought, and it actually takes a two year apprenticeship to learn the trade, so for a robot to do it so well

developed by swiss researchers, uses an electrical spinal cord implant. it is the first time someone whose spine has been completely severed has had the ability to walk restored. our science correspondent pallab ghosh has the story. michel roccati was paralysed after a motorbike accident five years ago. his spinal cord was completely severed and he has no feeling in his legs. but he can now walk because of an electrical implant that s been surgically inserted on his spine. using a remote control, he s able to send signals to his leg muscles, which enables michel to walk. it s the first time that someone this injured has been able to walk like this. michel, i can t believe that you were paralysed once. i know, it s very close to before the accident, yes. i stand up, i walk where i want alone, i can do the stairs. and.go, go, go, go! this is michel when he first
and.go, go, go, go! this is michel when he first had his implant in 2020. it gave him some small movement straightaway. nerves in the spinal cord send signals from the brain to the legs. some people are paralysed when the nerves are damaged through injury. in michel s case, there is no signal at all to the legs because the spinal cord is completely severed. but the implant sends signals directly to his legs, enabling him to walk. it just got stimulated. david m zee is another patient helping scientists with their research. it looks like it works! ..which has been published in nature medicine. they don t use the technology to help them walk in their everyday lives instead, they use it to practise walking, which exercises their muscles. this is not the cure for spinal cord injury, but it is a critical step to improve people s quality of life. we are going to empower them with the ability to stand, maybe make some steps.
