It’s been a massive year for Mark. He was just out of hospital and back home at the start of 2012, and walking for more than an hour (with a little help!) by the end. Here’s a video of Mark’s record-breaking day in his robotic legs, this month.

Just 12 months ago, Mark took his first small steps in his robotic legs at Ekso Bionics in San Francisco, California. Now he’s confidently walking in the bionic legs you helped him buy – more than 2000 steps at a time – with no help at all! This week, he recorded his record, at 2,196 steps in just an hour.
